13 Local Marketing Strategies That Work In 2022

You can reach valuable leads through local online and offline marketing.

You must develop effective local marketing strategies to build your brand authority and attract more customers.

A digital marketing strategy is essential, regardless of whether you are starting a new business or already have one.

Digital and social media marketing are the most crucial parts of marketing a local business since, according to Google, “83% of U.S. shoppers who visited a store in the last week say they used online search before going into a store.”

We’ll cover some of the online marketing tactics and strategies we’ve used with great success in reaching a local audience.

Great Local Marketing Strategies For This Year

1. Optimize For Local Search

Through Google Business Profile (GBP), your business will appear as soon as someone searches for your business or keywords on Google.

It is free, which is awesome.

The results will feature businesses within the vicinity of the person searching and even includes your business on Google Maps.

To start, create a profile with your company name, contact details, industry, etc.

Then, verify your GBP listing.

Once verified, you can add images and a bio, upload blogs, create offers, send and receive messages, add customer reviews, and see analytics.

Plus, it is pretty easy to update, so you always have relevant info online.

You can go one step further and set the business up with a solid, local link-building strategy.

Using citation sources such as Yellowpages.com tells Google where your company is located.

Plus, GBP has a great function that allows you to set the radius on services to a specific radius, such as 10km.

It is important to add fresh content or blog posts to your GBP account regularly.

Considering that a post expires after seven days, you’ll likely need to schedule a post at least once a week. Why is this important?

GBP posts can help drive traffic and engagement.

Do you have a sale or event coming up? You can promote anything related to the business on GBP.

If you’re not confident you’ll remember to upload a blog weekly, use content scheduling apps and tools like Semrush and Hootsuite.

As far as hyper-localized visibility goes, GBP is a no-brainer.

2. Local Reviews From Local Customers

As cautious online users, the first thing people notice is often the reviews given on the GBP listing.

A positive review or testimonial can demonstrate to local customers that you are a business they can trust.

That goes a long way in moving customers through the sales funnel towards conversion or purchase.

So, how do you get reviews?

While I don’t advocate directly asking for reviews from your existing customers – and definitely not paying for reviews – there are less direct ways of reminding customers to post positive reviews.

Got negative reviews? No problem.

You can use negative reviews as a way to gather meaningful customer information.

Not only will you get insight on how you can improve products or customer experience (CX), but you can use the opportunity to turn the negative review into a positive one by reaching out to the customer and correcting the poor experience, product, or service.

3. SEO Optimize Your Website

The next step to getting your brand and product into the local market is to optimize your website for organic search.

The first and foremost way of doing that is through keyword optimization.

While a lot of this will be intuitive at first, you will soon run out of clever ideas and need to do keyword research.

Competition on short-tail keywords is fierce, and someone who’s been around longer than you is almost guaranteed to be already ranking for it.

So, focus on long-tail, geo-specific keywords.

These are ideal because people who use long tail keywords usually know what they want (they’re not tire-kickers), and they are more ready to engage.

Advertisement

Those who use geo-specific keywords know where they want to do business.

So, say you are a digital marketing company that provides B2B marketing services for businesses in a specific area.

It would be futile to optimize just for “marketing” or ”digital marketing.” That ship has sailed!

Rather, create pages on the site that are location-based, niche-oriented, and have long-tail keywords.

For example, you can create a page or blog called “Digital marketing for B2B Companies in California” or “How B2B companies in California can benefit from digital marketing.”

You get the picture.

Advertisement

That means search engine results pages (SERPs) will show results for users searching for “digital marketing companies near me.”

4. Create Localized Content

Content marketing is a big part of attracting a targeted audience, which connects to inbound marketing.

We have found that the more valuable, relevant, and consistent your content is, the more your target audience will engage with it.

But where do you start?

Create content that solves your customer’s pain points and that is evergreen.

There’s no shortcut when it comes to good content creation. Do the research, write for humans, and Google bots will love it, too.

Advertisement

For this, we love “how-to” blogs, whitepapers, ebooks, infographics, videos, and other long-form blogs (more than 900 words).

That way, your content will help prospective customers find your website when looking for solutions.

In this example, when the person enters a long-tail keyword, “best flowers for weddings,” Google brings ads that match the search term.

It also brings organic results. Best of all, it creates “People also ask” (PAA) questions.

These could include, “What is the average cost of flowers for a wedding?”

Why not use these as a guide for fresh content ideas?

Advertisement

This kind of SEO-rich, high-value content attracts new visitors to your site and establishes your brand as the leader and authority on the subject matter.

You’ll see better results for your business by integrating content marketing into your local online marketing strategy.

5. Review Your Website’s Design

The look and feel of your website are as important as the words and content that make you findable on search engines.

However, while keywords will get the visitors to your site, your design and user experience (UX) will keep them there.

Use images and videos on your website that reference your location, neighborhood, and business so that there is a recognizable reference to your localized entity.

Also, the internet is evolving as rapidly as consumers’ needs are.

Advertisement

So, your website that was on the bleeding edge of design when you published it five years ago probably doesn’t quite toe the mark anymore.

It might be time for a redesign.

The most important thing to safeguard on your website is your user’s experience.

The site must be easy to use, easy to navigate, and easy to understand.

6. Integrate CRM Tool

Customer relationship manager (CRM) solutions ensure we have a tighter grasp on our understanding of our customers.

Most CRMs can integrate with modern websites. But how does your website feed prospect data into the CRM?

Advertisement

For one, you could consider adding a pop-up on your website.

It could be an invitation to subscribe to your newsletter, view a limited promotion, or announce a new product launch.

When linked to your CRM, your lead generation landing pages will also automatically update your CRM, such as HubSpot or Salesforce.

Not only does this feed your pipeline, but it also improves first-party data and targeting and thus makes your marketing messaging that much better.

Also, localized campaigns can be launched via your CRM.

You can easily identify and segment customers and prospects by region if the data has been captured accordingly in your CRM.

Advertisement

Remember, the quality of data you capture is the quality of output you’ll get.

That can be used for personalized invitations to in-person events and activations, for email campaigns that are area-specific, and so on.

7. Attract Local Visitors Through Google Ads

As I’ve always said, if you want sales, you need to advertise. Google Ads is just that.

While SEO is great for local organic search, you need Google Ads and other paid media channels to support your lead generation and brand awareness campaigns.

Google Ads is a keyword-driven, pay-per-click channel that allows you to target audiences based on keywords and location (amongst other things).

Your creative copy and solutions-driven content will help capture your local market until your SEO is in full swing.

Advertisement

When setting up your Google Ads, implement conversion tracking – which will help you optimize your campaigns and pivot toward optimal business success.

It also aligns marketing tactics with sales goals and ultimately supports business growth.

For example, one of our clients is a health and fitness gym.

We’re only targeting people within a 10 km radius around their seven gyms through Google Ads.

This way, we get maximum return on investment (ROI) on money spent.

8. Feed The Funnel With Remarketing

Remarketing is an important element of your localized digital marketing arsenal.

Advertisement

That’s effective if your SEO or Google ad didn’t do the job the first time or the customer is still in the consideration phase of the buyer journey.

Remarketing supports other, more geolocation-specific tactics when considering how to strengthen your local marketing strategies.

So, if your Google Ads campaign (geolocation-limited) or your paid social campaign (likewise, demographics-oriented) sends traffic to your site, remarketing supports these by following those visitors around after the fact.

In the end, remarketing increases conversions, promotes brand awareness, and helps you stay top of mind with prospects.

9. Get The Phone Going With Google Call-Only Ads

If you rely heavily on phone calls to generate business, then Google call-only ads could prove invaluable and ideal for localized marketing.

That’s because, as with other Google products, you can target a specific demographic in your call-only ads.

Advertisement

It’s also a good option if you don’t have any specific landing pages simply because your product or service doesn’t need it, and a direct phone call just works better.

One downside of local online marketing may be that you will not receive all qualified calls.

10. Insist On CRO-Optimized Landing Pages For Each Campaign

Contrary to popular belief, your home page is not your landing page.

Your home page is your home page.

It is a summary of your website with many exit points to other pages, many different calls to action (CTAs) – such as “learn more” and “contact us” – and many different focuses.

A landing page has one job: conversion.

Advertisement

If you’re spending money on an ad campaign, you need those clicks to work hard.

To do this, you need a landing page designed specifically for that campaign, with lead-gen in mind.

So, the tried-and-trusted format is:

  • Emotive copy that includes a pain point and solution.
  • An image that evokes a feeling.
  • A CTA above the fold.
  • Below the fold, you can have your trust queues, testimonials, benefits, and so on.
  • The footer can reiterate the CTA.

That’s it.

No buttons and links that take you away from the page.

No clicks are needed to expand sections. The only click available on the page is “Buy now” or “Submit” (or whatever the desired action is).

Rinse and repeat for each campaign.

Advertisement

11. Leverage Social Media

Social media can be a great way to grow local brand awareness and engagement.

For one, community groups often already have all your desired customers in one place.

Remember, you need to be active on the social media channels your target audience prefers.

It might not be your local watering hole, so you need to get comfortable with using platforms like TikTok and Instagram for Gen Z and Gen Y audiences, while Facebook is great for Gen X and Boomers.

LinkedIn is ideal for B2B targeting.

Post organic content, like status updates, photos, and videos, or run ad campaigns.

Advertisement

Much like Google Ads, most social platforms allow you to geo-target your campaigns.

This is great for localized marketing.

For example, if you have a brick-and-mortar location, you can focus your social media ads on reaching all people within a 10km radius of your location.

These enable super-localized and targeted marketing tactics.

12. Video Tells Your Homegrown Story

Video is now preferred over all other visual mediums by more consumers. In fact, 95% of enterprise B2B conversions are aided by video.

Keep it personal, keep it local, and direct your video content at the customer’s point of pain that you can solve.

Advertisement

Your video assets don’t all need to be ads. You can have testimonials and how-tos embedded into your site or published on YouTube.

Just make sure you tell a story and that – in the story – your customer is the hero, and you are simply the guide who helps them succeed.

13. Offline Activations And Events

Offline activations and events are one of our favorite ways of bolstering local marketing.

Working in conjunction with your online activities – such as email, ads, and social – this “boots on the ground” approach yields amazing results.

Take advantage of the physical proximity you have to your local customers.

Consider loyalty cards, charity sponsorships, referral programs, networking breakfasts, and other community-strengthening events.

Advertisement

All of these add tremendous gravitas to your brand and allow you to connect with your target audience locally.

Final Thoughts

With so many ways to be found online locally, we are confident your local target audience will discover your products and services.

Be sure to activate and be active on Google Business Profile.

Keep your website fresh and user-friendly, and remember to regularly add content (blogs).

Find communities on social media, and create ads on Google and social platforms that minutely reach your desired audience.

Find communities in real life, and create events and activities in which the local target audience can participate.

Advertisement

All of this contributes to brand reinforcement.

Finally, remember always to position your customer as the hero, as you solve their pain points right where they are.

Understanding the Impact of Google's November 2024 Core Update on Global Search Rankings

Introduction

In November 2024, Google launched its latest core algorithm update, a broad refinement designed to enhance the quality of its search engine results. Rolling out over approximately two weeks, the update continues Google’s ongoing commitment to delivering more relevant, useful, and high-quality search experiences for users worldwide. This article explores the nature of the November 2024 Core Update, its potential impact on websites, and strategies for site owners to adapt and thrive in its aftermath​.

1. What Is a Google Core Update?

Core updates are large-scale changes to Google’s search algorithms. Unlike targeted updates aimed at specific sectors or issues, core updates broadly impact all regions and languages. They reflect Google’s effort to re-evaluate how content is assessed and ranked based on relevance, usefulness, and reliability. Previous updates include significant releases like the March and August 2024 updates, illustrating the frequency and scope of these changes​.

2. Goals of the November 2024 Core Update

The November update focuses on refining the quality of search results. According to Google’s official statements, it seeks to amplify genuinely useful content while reducing the visibility of content primarily designed to manipulate rankings without meeting user needs. This effort emphasizes Google’s consistent push for “people-first” content—engaging and useful information that serves users, not search engines​.

3. Key Features and Characteristics of the Update

  • Global Impact: The update affects search rankings on a global scale and is not confined to any particular industry or niche​.
  • Rollout Duration: Spanning about two weeks, the rollout’s timing allows Google to fully implement algorithmic changes and assess their effects.
  • Broad Adjustments: The update doesn’t target specific sites but involves systemic reassessment across Google’s ranking systems.
  • Dynamic Search Environment: This core update follows in the footsteps of the August and March 2024 updates, representing a year of significant search result refinement​.

4. What This Means for Site Owners

  • Traffic Fluctuations: Websites may observe shifts in rankings and traffic during the update’s rollout and subsequent completion. These changes highlight the dynamic nature of Google search and require continuous monitoring and adaptation​.
  • Recommended Actions:
    • Wait and Analyze: Site owners experiencing changes should wait until the rollout’s completion before making significant adjustments.
    • Utilize Google Search Console: Compare traffic and ranking data from before and after the update to identify potential areas of improvement.
    • Focus on High-Impact Pages: Pages with notable drops in ranking should undergo thorough content evaluation using Google’s guidelines

5. Recovery and Adaptation Strategies

Recovering from a negative impact due to a core update may take weeks or months as Google’s systems adjust and validate content changes. Site owners should prioritize delivering high-quality, reliable, and user-focused content. Specific steps include:

  1. Content Evaluation: Assess content against Google’s guidelines, focusing on readability, user satisfaction, and factual accuracy.
  2. No Quick Fixes: Avoid superficial changes aimed solely at improving rankings. Sustainable improvements are more valuable and impactful​(November 2024 core upda…).
  3. People-First Content: Ensure content serves real user needs, as opposed to purely SEO-driven objectives. This aligns with Google’s long-term priorities for search quality​

6. Comparative Analysis with Previous Updates

The November 2024 Core Update continues trends observed in previous updates like March and August 2024. While each update has its nuances, their collective goal remains consistent: bettering search quality and delivering relevant results. Comparing data from these updates can reveal patterns and offer insights into Google’s evolving criteria​

7. Broader Implications for the SEO Industry

Google’s ongoing core updates underscore the critical importance of a user-centric approach to SEO. For digital marketers and SEO specialists, adapting strategies to these updates involves staying informed, using reliable analytics tools, and keeping content fresh and engaging. The need for adaptability is paramount, as Google continually shifts the parameters of what defines quality content

Conclusion

The November 2024 Core Update serves as a reminder that Google’s algorithmic changes are not designed to punish but to reward helpful, authentic, and user-focused content. Site owners and marketers who embrace this philosophy are better positioned to weather core updates and even benefit from improved rankings and traffic over time. By maintaining a focus on user experience, transparency, and relevance, creators can align with Google’s evolving standards and thrive in the ever-changing digital landscape

How to Revive an Old Blog Article for SEO

Step-by-Step: How to Optimize Old Blog Posts for SEO

Quick question: What do you typically do with your old blog posts? Most likely, the answer is: Not much.

If that’s the case, you’re not alone. Many of us in SEO and content marketing tend to focus on continuously creating new content, rather than leveraging our existing blog posts.

However, here’s the reality—Google is becoming increasingly sophisticated in evaluating content quality, and we need to adapt accordingly. Just as it’s easier to encourage existing customers to make repeat purchases, updating old content on your website is a more efficient and sustainable strategy in the long run.

Ways to Optimize Older Content 

Some of your old content might not be optimized for SEO very well, rank for irrelevant keywords, or drive no traffic at all. If the quality is still decent, however, you should be able to optimize it properly with little effort. 

Refresh Content 

If your blog post contains a specific year or mentions current events, it may become outdated over time. If the rest of the content is still relevant (like if it’s targeting an evergreen topic), simply updating the date might be all you need to do.

Rewrite Old Blog Posts 

When the content quality is low (you might have greatly improved your writing skills since you’ve written the post) but the potential is still there, there’s not much you can do apart from rewriting an old blog post completely. 

Advertisement



This is not a waste—you’re saving time on brainstorming since the basic structure is already in place. Now, focus on improving the quality.

Delete Old Blog Posts 

You might find a blog post that just seems unusable. Should you delete your old content? It depends. If it’s completely outdated, of low quality, and irrelevant to any valuable keywords for your website, it’s better to remove it. 

Once you decide to delete the post, don’t forget to set up a 301 redirect to a related post or page, or to your homepage.

Promote Old Blog Posts 

Sometimes all your content needs is a bit of promotion to start ranking and getting traffic again. Share it on your social media, link to it from a new post – do something to get it discoverable again to your audience. This can give it the boost it needs to attract organic links too.

Which Blog Posts Should You Update?

Deciding when to update or rewrite blog posts is a decision that relies on one important thing: a content audit. 

Use your Google Analytics to find out which blog posts used to drive tons of traffic, but no longer have the same reach. You can also use Google Search Console to find out which of your blog posts have lost visibility in comparison to previous months. I have a guide on website analysis using Google Analytics and Google Search Console you can follow.

Advertisement



If you use keyword tracking tools like SE Ranking, you can also use the data it provides to come up with a list of blog posts that have dropped in the rankings. 

Make data-driven decisions to identify which blog posts would benefit from these updates – i.e., which ones still have the chance to recover their keyword rankings and organic traffic. 

With Google’s helpful content update, which emphasizes better user experiences, it’s crucial to ensure your content remains relevant, valuable, and up-to-date.

How To Update Old Blog Posts for SEO

Updating articles can be an involved process. Here are some tips and tactics to help you get it right.

Author’s Note: I have a Comprehensive On-Page SEO Checklist you might also be interested in following while you’re doing your content audit.

Conduct New Keyword Research

Updating your post without any guide won’t get you far. Always do your keyword research to understand how users are searching for your given topic. 

Advertisement



Proper research can also show you relevant questions and sections that can be added to the blog post you’re updating or rewriting. Make sure to take a look at the People Also Ask (PAA) section that shows up when you search for your target keyword. Check out other websites like Answer The Public, Reddit, and Quora to see what users are looking for too. 

Look for New Ranking Opportunities

When trying to revive an old blog post for SEO, keep an eye out for new SEO opportunities (e.g., AI Overview, featured snippets, and related search terms) that didn’t exist when you first wrote your blog post. Some of these features can be targeted by the new content you will add to your post, if you write with the aim to be eligible for it. 

Rewrite Headlines and Meta Tags

If you want to attract new readers, consider updating your headlines and meta tags. 

Your headlines and meta tags should fulfill these three things:

  1. Reflect the rewritten and new content you’ve added to the blog post.
  2. Be optimized for the new keywords it’s targeting (if any).
  3. Appeal to your target audience – who may have changed tastes from when the blog post was originally made. 

Remember that your meta tags in particular act like a brief advertisement for your blog post, since this is what the user first sees when your blog post is shown in the search results page. 

Take a look at your blog post’s click-through rate on Google Search Console – if it falls below 2%, it’s definitely time for new meta tags. 

Replace Outdated Information and Statistics

Updating blog content with current studies and statistics enhances the relevance and credibility of your post. By providing up-to-date information, you help your audience make better, well-informed decisions, while also showing that your content is trustworthy.

Advertisement



Tighten or Expand Ideas

Your old content might be too short to provide real value to users – or you might have rambled on and on in your post. It’s important to evaluate whether you need to make your content more concise, or if you need to elaborate more. 

Keep the following tips in mind as you refine your blog post’s ideas:

  • Evaluate Helpfulness: Measure how well your content addresses your readers’ pain points. Aim to follow the E-E-A-T model (Experience, Expertise, Authoritativeness, Trustworthiness).
  • Identify Missing Context: Consider whether your content needs more detail or clarification. View it from your audience’s perspective and ask if the information is complete, or if more information is needed.
  • Interview Experts: Speak with industry experts or thought leaders to get fresh insights. This will help support your writing, and provide unique points that enhance the value of your content.
  • Use Better Examples: Examples help simplify complex concepts. Add new examples or improve existing ones to strengthen your points.
  • Add New Sections if Needed: If your content lacks depth or misses a key point, add new sections to cover these areas more thoroughly.
  • Remove Fluff: Every sentence should contribute to the overall narrative. Eliminate unnecessary content to make your post more concise.
  • Revise Listicles: Update listicle items based on SEO recommendations and content quality. Add or remove headings to stay competitive with higher-ranking posts.

Improve Visuals and Other Media

No doubt that there are tons of old graphics and photos in your blog posts that can be improved with the tools we have today. Make sure all of the visuals used in your content are appealing and high quality. 

Update Internal and External Links

Are your internal and external links up to date? They need to be for your SEO and user experience. Outdated links can lead to broken pages or irrelevant content, frustrating readers and hurting your site’s performance.

You need to check for any broken links on your old blog posts, and update them ASAP. Updating your old blog posts can also lead to new opportunities to link internally to other blog posts and pages, which may not have been available when the post was originally published.

Optimize for Conversions

When updating content, the ultimate goal is often to increase conversions. However, your conversion goals may have changed over the years. 

So here’s what you need to check in your updated blog post. First, does the call-to-action (CTA) still link to the products or services you want to promote? If not, update it to direct readers to the current solution or offer.

Second, consider where you can use different conversion strategies. Don’t just add a CTA at the end of the post. 

Advertisement



Last, make sure that the blog post leverages product-led content. It’s going to help you mention your products and services in a way that feels natural, without being too pushy. Being subtle can be a high ROI tactic for updated posts.

Key Takeaway

Reviving old blog articles for SEO is a powerful strategy that can breathe new life into your content and boost your website’s visibility. Instead of solely focusing on creating new posts, taking the time to refresh existing content can yield impressive results, both in terms of traffic and conversions. 

By implementing these strategies, you can transform old blog posts into valuable resources that attract new readers and retain existing ones. So, roll up your sleeves, dive into your archives, and start updating your content today—your audience and search rankings will thank you!

How Compression Can Be Used To Detect Low Quality Pages

Published

on

By

Compression can be used by search engines to detect low-quality pages. Although not widely known, it's useful foundational knowledge for SEO.

The concept of Compressibility as a quality signal is not widely known, but SEOs should be aware of it. Search engines can use web page compressibility to identify duplicate pages, doorway pages with similar content, and pages with repetitive keywords, making it useful knowledge for SEO.

Although the following research paper demonstrates a successful use of on-page features for detecting spam, the deliberate lack of transparency by search engines makes it difficult to say with certainty if search engines are applying this or similar techniques.

What Is Compressibility?

In computing, compressibility refers to how much a file (data) can be reduced in size while retaining essential information, typically to maximize storage space or to allow more data to be transmitted over the Internet.

TL/DR Of Compression

Compression replaces repeated words and phrases with shorter references, reducing the file size by significant margins. Search engines typically compress indexed web pages to maximize storage space, reduce bandwidth, and improve retrieval speed, among other reasons.

This is a simplified explanation of how compression works:

  • Identify Patterns:
    A compression algorithm scans the text to find repeated words, patterns and phrases
  • Shorter Codes Take Up Less Space:
    The codes and symbols use less storage space then the original words and phrases, which results in a smaller file size.
  • Shorter References Use Less Bits:
    The “code” that essentially symbolizes the replaced words and phrases uses less data than the originals.

A bonus effect of using compression is that it can also be used to identify duplicate pages, doorway pages with similar content, and pages with repetitive keywords.

Research Paper About Detecting Spam

This research paper is significant because it was authored by distinguished computer scientists known for breakthroughs in AI, distributed computing, information retrieval, and other fields.

Marc Najork

One of the co-authors of the research paper is Marc Najork, a prominent research scientist who currently holds the title of Distinguished Research Scientist at Google DeepMind. He’s a co-author of the papers for TW-BERT, has contributed research for increasing the accuracy of using implicit user feedback like clicks, and worked on creating improved AI-based information retrieval (DSI++: Updating Transformer Memory with New Documents), among many other major breakthroughs in information retrieval.

Dennis Fetterly

Another of the co-authors is Dennis Fetterly, currently a software engineer at Google. He is listed as a co-inventor in a patent for a ranking algorithm that uses links, and is known for his research in distributed computing and information retrieval.

Those are just two of the distinguished researchers listed as co-authors of the 2006 Microsoft research paper about identifying spam through on-page content features. Among the several on-page content features the research paper analyzes is compressibility, which they discovered can be used as a classifier for indicating that a web page is spammy.

Detecting Spam Web Pages Through Content Analysis

Although the research paper was authored in 2006, its findings remain relevant to today.

Then, as now, people attempted to rank hundreds or thousands of location-based web pages that were essentially duplicate content aside from city, region, or state names. Then, as now, SEOs often created web pages for search engines by excessively repeating keywords within titles, meta descriptions, headings, internal anchor text, and within the content to improve rankings.

Section 4.6 of the research paper explains:

“Some search engines give higher weight to pages containing the query keywords several times. For example, for a given query term, a page that contains it ten times may be higher ranked than a page that contains it only once. To take advantage of such engines, some spam pages replicate their content several times in an attempt to rank higher.”

The research paper explains that search engines compress web pages and use the compressed version to reference the original web page. They note that excessive amounts of redundant words results in a higher level of compressibility. So they set about testing if there’s a correlation between a high level of compressibility and spam.

They write:

“Our approach in this section to locating redundant content within a page is to compress the page; to save space and disk time, search engines often compress web pages after indexing them, but before adding them to a page cache.

…We measure the redundancy of web pages by the compression ratio, the size of the uncompressed page divided by the size of the compressed page. We used GZIP …to compress pages, a fast and effective compression algorithm.”

High Compressibility Correlates To Spam

The results of the research showed that web pages with at least a compression ratio of 4.0 tended to be low quality web pages, spam. However, the highest rates of compressibility became less consistent because there were fewer data points, making it harder to interpret.

Figure 9: Prevalence of spam relative to compressibility of page.

The researchers concluded:

“70% of all sampled pages with a compression ratio of at least 4.0 were judged to be spam.”

But they also discovered that using the compression ratio by itself still resulted in false positives, where non-spam pages were incorrectly identified as spam:

Advertisement



“The compression ratio heuristic described in Section 4.6 fared best, correctly identifying 660 (27.9%) of the spam pages in our collection, while misidentifying 2, 068 (12.0%) of all judged pages.

Using all of the aforementioned features, the classification accuracy after the ten-fold cross validation process is encouraging:

95.4% of our judged pages were classified correctly, while 4.6% were classified incorrectly.

More specifically, for the spam class 1, 940 out of the 2, 364 pages, were classified correctly. For the non-spam class, 14, 440 out of the 14,804 pages were classified correctly. Consequently, 788 pages were classified incorrectly.”

The next section describes an interesting discovery about how to increase the accuracy of using on-page signals for identifying spam.

Insight Into Quality Rankings

The research paper examined multiple on-page signals, including compressibility. They discovered that each individual signal (classifier) was able to find some spam but that relying on any one signal on its own resulted in flagging non-spam pages for spam, which are commonly referred to as false positive.

The researchers made an important discovery that everyone interested in SEO should know, which is that using multiple classifiers increased the accuracy of detecting spam and decreased the likelihood of false positives. Just as important, the compressibility signal only identifies one kind of spam but not the full range of spam.

Advertisement



The takeaway is that compressibility is a good way to identify one kind of spam but there are other kinds of spam that aren’t caught with this one signal. Other kinds of spam were not caught with the compressibility signal.

This is the part that every SEO and publisher should be aware of:

“In the previous section, we presented a number of heuristics for assaying spam web pages. That is, we measured several characteristics of web pages, and found ranges of those characteristics which correlated with a page being spam. Nevertheless, when used individually, no technique uncovers most of the spam in our data set without flagging many non-spam pages as spam.

For example, considering the compression ratio heuristic described in Section 4.6, one of our most promising methods, the average probability of spam for ratios of 4.2 and higher is 72%. But only about 1.5% of all pages fall in this range. This number is far below the 13.8% of spam pages that we identified in our data set.”

So, even though compressibility was one of the better signals for identifying spam, it still was unable to uncover the full range of spam within the dataset the researchers used to test the signals.

Combining Multiple Signals

The above results indicated that individual signals of low quality are less accurate. So they tested using multiple signals. What they discovered was that combining multiple on-page signals for detecting spam resulted in a better accuracy rate with less pages misclassified as spam.

The researchers explained that they tested the use of multiple signals:

“One way of combining our heuristic methods is to view the spam detection problem as a classification problem. In this case, we want to create a classification model (or classifier) which, given a web page, will use the page’s features jointly in order to (correctly, we hope) classify it in one of two classes: spam and non-spam.”

These are their conclusions about using multiple signals:

“We have studied various aspects of content-based spam on the web using a real-world data set from the MSNSearch crawler. We have presented a number of heuristic methods for detecting content based spam. Some of our spam detection methods are more effective than others, however when used in isolation our methods may not identify all of the spam pages. For this reason, we combined our spam-detection methods to create a highly accurate C4.5 classifier. Our classifier can correctly identify 86.2% of all spam pages, while flagging very few legitimate pages as spam.”

Key Insight:

Misidentifying “very few legitimate pages as spam” was a significant breakthrough. The important insight that everyone involved with SEO should take away from this is that one signal by itself can result in false positives. Using multiple signals increases the accuracy.

What this means is that SEO tests of isolated ranking or quality signals will not yield reliable results that can be trusted for making strategy or business decisions.

Takeaways

We don’t know for certain if compressibility is used at the search engines but it’s an easy to use signal that combined with others could be used to catch simple kinds of spam like thousands of city name doorway pages with similar content. Yet even if the search engines don’t use this signal, it does show how easy it is to catch that kind of search engine manipulation and that it’s something search engines are well able to handle today.

Here are the key points of this article to keep in mind:

  • Doorway pages with duplicate content is easy to catch because they compress at a higher ratio than normal web pages.
  • Groups of web pages with a compression ratio above 4.0 were predominantly spam.
  • Negative quality signals used by themselves to catch spam can lead to false positives.
  • In this particular test, they discovered that on-page negative quality signals only catch specific types of spam.
  • When used alone, the compressibility signal only catches redundancy-type spam, fails to detect other forms of spam, and leads to false positives.
  • Combing quality signals improves spam detection accuracy and reduces false positives.
  • Search engines today have a higher accuracy of spam detection with the use of AI like Spam Brain.
