8 Stories Of Hope From The SEO Community

February 23, 2022, was a regular Wednesday for Ukrainian marketers and SEO specialists.

We had our morning coffees and did tech audits, built some links, and revamped a couple of landing pages.

We were striving for better visibility and conversions, trying hard to keep up with the deadlines, and hoping to reach our KPIs.

Then, on February 24, the whole of Ukraine woke up in a newly fragile and terrifying world.

Our plans, aspirations, and priorities were transformed.

From that day on, the only thing that mattered was saving the lives of our families, helping those in need to survive the turmoil of war, and defending our right to live freely on our own land.

For this column, my team reached out to eight Ukrainian SEO and marketing specialists and asked them to share their experiences in the time since our world turned upside down.

It turns out they all had one thing in common: in a shattered world full of painful uncertainty, they’ve drawn strength from helping others and contributing to Ukraine’s future victory.

Here is how they’re doing it.

Bringing Accurate News To Russian People

Artem Pylypets is the Head of SEO at SEO7, lecturer, and the founder of an educational YouTube channel “Школа SEO”  (SEO School).

Before the war started, Artem’s life was all about doing SEO himself and sharing his knowledge with others.

He led the SEO department at SEO7, ran his YouTube channel called “Школа SEO”  (“SEO School), and conducted online training on SEO matters.

Currently, Artem is doing all the same things, but to the sound of artillery shelling.

War brought many challenges to his work. SEO7 team members are now scattered across Europe since many people had to flee their homes.

They are trying to streamline their operations, but it isn’t easy.

Besides, many SEO7 customers seized their operations, which left the team struggling to stay afloat with the few clients who target the U.S. and European markets.

Artem himself stayed in the Kyiv suburbs. He confessed that he is used to hearing artillery shelling and added that it is “not that heavy.”

His neighborhood community has set up roadblocks, and people guard them in shifts to control the situation.

“It really pleases me to see how the war united my fellow Ukrainians. The way we help each other, the way we fight for our land, is just amazing.

At the same time, I must admit that I’d rather have a peaceful sky above my head.”

Like many other SEO specialists, Artem decided to use his SEO skills to help Ukraine win the informational war.

His goal is to help Russian search engine users see the true stories of war and not the deceitful official propaganda. For this to happen, he has been working on improving the visibility of international media in the Russian SERPs.

When the war ends, Artem plans to keep building his business and hopes to launch all the projects he always wanted to but never had the time for.

He’s looking forward to reading some good news – not reporting on mounting casualties and destruction in Kharkiv, Sumy, Chernihiv, Mariupol, and other cities.

All he dreams of is celebrating Ukraine’s victory with his closest friends.

Volunteering 24/7 To Help Those In Need

Andrey Kapeltsov is the founder of SEO.Capital and a keynote speaker at leading SEO, Affiliate, and iGaming conferences in Ukraine. He has spent the last 18 years mastering SEO and is always looking for new out-of-the-box ways to keep up with search algorithm updates.

Since 2015, he’s focused on the iGaming industry, working as the CMO at major gaming and betting companies.

Because of the specific nature of the iGaming niche, SEO has always been at the core of every marketing strategy Andrey developed.

Today, Andrey is trying to serve his country and people in every way possible.

Some of his company’s employees lived in the cities ravaged by the Russian army – Andrey helped them escape to a safer place.

Today, he continues to help evacuate people from the shelled cities on the frontline to a place to live in the central and western parts of Ukraine.

With employees moved to safe places, Andrey decided to restore his company’s operations to support Ukraine’s economy – his business provides donations to the Ukrainian armed forces.

Also, they’ve established a charity foundation to support displaced families and volunteers.

In addition to helping out financially, Andrey and his colleagues spend their evenings at humanitarian aid centers unloading goods.

Andrey says that this kind of physical activity works just as well as going to the gym.

“What fascinates me is how the war forced us to quickly establish complex processes – it seemed unachievable in times of peace.

I still sometimes face difficulties finding particular military equipment, but my friends and new acquaintances always help me out.

Advertisement

I had the pleasure of meeting so many great people over the past weeks.”

Andrey notes that his life before the war started seems very distant and blurred. He has a feeling that war lasts forever but has found a role that works for him and is ready to carry on.

When it’s all over, Andrey plans to keep developing his business and actively participate in helping Ukraine recover.

He hopes to spend some time living by the sea, where the only sound would be that of the sea waves. But first, Ukraine has to win.

Helping Ukrainian SEOs Find New Jobs

Olesia Korobka is an SEO entrepreneur running multiple projects before the war started. She offered guidance and consulting to businesses and ran a couple of her own projects sponsored by third parties.

Unfortunately, she had to stop working with most sponsors because of their country of origin.

That left her with mostly consulting. She can now keep up with the tasks, but for a while could not work because of a slow internet connection.

Olesia, her son, and her mother were among the 4 million Ukrainians who had to flee their homes.

First, they moved to Poland and then to the Netherlands, where she could get back to work, which she admitted was challenging.

“My brain was reluctant to focus on complex technical tasks.

After operating in survival mode for a while, the first time I looked into coding, I spent several hours on a task that took me 5 to 15 minutes before, and I still wasn’t sure if I did it right.”

At the same time, working on her projects was something she needed badly. It was the only thing that helped Olesia feel she was doing okay and making a positive impact.

What inspired her was the new project she organized to support the Ukrainian SEO community. Since the war started, many people have approached Olesia asking for help finding a new job. Many Ukrainian SEO specialists lost their only source of income and felt desperate.

This is how Olesia got the idea to create a listing of Ukrainian SEOs that briefly describes their skills and areas of expertise.

She contacted Aleyda Solis with a request to share the listing on her Twitter and in the #SEOFOMO newsletter, and Aleyda kindly supported the initiative.

Then, Olesia started receiving messages from different companies open to hiring Ukrainians, so she compiled a listing of job openings.

As more and more experts and businesses joined the initiative, the spreadsheet became messy. So, Olesia is currently working on creating multiple websites targeting employers in Australia, the USA, and particular European countries.

Once the sites are up and running, the job-seeking and hiring process should be much easier.

Olesia dreams of the war coming to an end so that she can return home.

She misses her normal life and the people.

Olesia adds that many Ukrainians will have to deal with PTSD once the war is over and won’t lead a normal life anytime soon.

However, she is determined to keep her chin up and carry on with her projects. Olesia is also grateful to everyone who’s supported her in the past weeks.

“Soooooo many people are helping me. It was amazing and kind of even uncomfortable. I’ve never had that in my entire life and never expected that.

I kind of feel a bit guilty, but also very grateful. Thank you all for your support and input.

I cannot always find the proper words to thank everyone, but I’m super grateful for everything.”

Saving Ukrainian Four-Legged Cuties

Anton Shulke is the Head of Influencer marketing at Duda.co and livestream production manager.

Since 2015, Anton has held live events, webinars, and podcasts for leading companies in the SEO industry, such as Duda, Semrush, and Kalicube.

Duda – Anton’s latest workplace – is not a Ukrainian company and wasn’t directly affected (even though the company had about a dozen employees in Ukraine).

Anton was offered paid time off when the war started, but he prefers to keep working, so he is still doing one webinar a week.

On top of that, Anton joined the Ukrainian SEO community to help the affected people by trying to arrange accommodation, find job opportunities, or provide direct financial help.

Anton was amazed by the reaction of the Ukrainian SEO community. He always believed there were many good people but didn’t expect to see such overwhelming support for the less fortunate ones.

Anton added that he felt honored to be a part of it.

He also started a small charity project for collecting funds for cat and dog shelters, which you can learn about and support here.

“I decided to help small shelters because I thought they could be under the radar of big charities, which tend to help children, refugees, and the army.

I get messages from people who run the shelters, and they seem to be surprised and extremely grateful for the help I provide, which gives me motivation to continue.

The hard part is that while initially the reaction from people was very positive and giving, donations are drying up as time passes.

Still, I understand that people get tired, and I cannot blame them.”

Anton hopes to keep his job at Duda, but he also considers putting more effort into the charity initiative.

He will probably keep the cat and dog shelter project, though the format may change.

Another thing he hopes to do is have a coffee with all the lovely people who message him on Facebook.

Every day, Anton publishes a ‘Good Morning’ post with a #coffeeshot on his Facebook page. In reply, many people say they’d love to have a coffee with him.

Protecting Ukrainian Land In The Armed Forces

Eugene Lata is the CMO at Lemon.io and an experienced marketer who has spent the last seven years building marketing teams and developing growth strategies.

Up until January 2022, he was the CMO at SerpStat, an SEO tool company based in Odesa.

He had begun a new job at the Lemon.io marketplace not long before the war started.

In the first days of the war, Eugene decided to join Odesa territorial defense forces, and currently, he is a member of the 122nd brigade.

Due to Eugene’s previous experience, he became a managing paramedic officer in the material supply squadron.

This means he is in charge of training other paramedics and forming special evacuation and emergency brigades.

Such brigades consist of one paramedic and four assault soldiers. They work on the frontline evacuating wounded soldiers and civilians.

Luckily, at the moment, there is no need to evacuate civilians in the regions where Eugene is located.

In addition to training paramedics, he trains various military units on NATO’s methodology of providing first aid.

This is not the first time Eugene decided to join the army. Back in 2014, after coming back home from the U.K., he spent six months in the Donbas region fighting the enemies with other volunteers who joined the Dnipro-1 battalion.

This was when he started helping wounded people as a paramedic.

Eight years later, his previous experience allowed Eugene to teach other officers to save lives.

“What inspires me is the progress the guys whom I train demonstrate.

Those who joined just three weeks ago with no relevant experience and no medical background are now trained well enough to provide qualified help. These people are already evacuating people and saving many lives in the Mykolaiv and Odesa regions.

Advertisement

Seeing this gives me a sense of accomplishment.”

Eugene confesses that he preferred his regular job, living under peaceful skies when his biggest worry was a wasted marketing budget or the spread of the coronavirus.

But until the war is over, he can’t imagine himself doing anything other than his current occupation.

When Ukraine wins, Eugene cannot wait to hug his family, now scattered around the country.

His wife and younger sister volunteer in Odesa, getting the necessary military ammunition for Eugene’s brigades.

He wants to go on a walk with his labrador dog.

Being an avid traveler, he’ll surely take on new adventures.

First thing, he’ll go to the Carpathian mountains. Eugene hopes for Ukraine to win before the spring ends – then he’ll enjoy the spring greenery while watching the sunrise.

He’ll also be working a lot because rebuilding a country takes many resources.

Finally, he wants to become a father – he and his wife had planned to start a family before the war broke out.

Fighting A Cyberwar Via SEO Community Chat

Igor Shulezhko is the CEO & Founder at rankUP and co-owner of Shmeo.Link. He has been in the business for over ten years as Head of SEO for several major Ukrainian brands.

Before the war started, he focused his efforts on building his SEO agency, rankUp.

Advertisement

His business was doing pretty well and boasted a varied customer profile that included startups and SaaS companies, ecommerce projects, and news portals.

All these customers were from Ukraine, which means the agency wasn’t impacted as much as other companies with close ties to Russia.

Still, the war forced many businesses to put their marketing spending on hold. Now Igor is trying hard to save his agency.

His team is currently scattered across Ukraine and works remotely.

Igor noted that he can feel how anxious everyone on the team is right now.

“Constantly monitoring the news is extremely exhausting. Besides, air raid sirens keep people awake at night—often there are two to four sirens per night with brief interruptions.

All this makes it hard to concentrate on your tasks. It’s easier to do SEO when all you need to focus on is the work.”

One of Igor’s projects is an SEO community on Telegram, an extremely popular messenger in Ukraine. Currently, the community unites about 5,000 people.

Before, it had more participants, but many Russians left once the community started spreading war-related messages.

Igor regretfully notes that many Russians in the group vocally supported Putin and denied all war crimes.

“When the war started, we restricted commenting in the community and limited publication rights to admins only,” he said.

The idea was to use the community chat to deliver the most important initiatives to its subscribers. They shared links to verified charities and details on evacuation opportunities, posted lists of Russian sites whose operations they were seeking to disrupt, and links to communities that spread false news so that community members could block them.

Igor believes that he and his team are contributing to winning the cyberwar against Russia by doing all this.

Igor admits that he misses his peaceful life.

When the war ends, the first thing he’ll do is visit his mom, who lives in the Sumy region.

Luckily, the town is not on the frontline, but with Russian troops all around, it suffers from a lack of supplies. Evacuation is currently too dangerous.

Telecommunications are still operating, so Igor can still regularly call his mother.

He dreams of seeing her in person and giving her a big hug.

Helping Ukrainian Families In Need

Max Karmazin is the Digital Marketing specialist, Country Manager (Germany) at SE Ranking. He returned to Ukraine in November 2021 after living in Switzerland for seven years.

Max was working on his Master’s degree in Sociology and Media Studies, working different jobs, and traveling.

Advertisement

As an expat, he always felt he had limited working hours, income, job, and social standing opportunities.

Feeling detached, he couldn’t completely embrace the new mentality and social rules.

Thus, he decided to return to Kyiv, and three months later, the war started.

The first days after the invasion were tough. Max couldn’t continue working because he was constantly distracted by the news.

When he left Kyiv on the third day of the war to get farther from the danger, he felt saving one’s life and leaving countrymen to fend for themselves wasn’t in accordance with his values.

Doing his regular job also felt wrong at that time.

Max decided he would join the army and fight the enemy back or start volunteering.

This led him to join the territorial defense forces, volunteer military units that protect city residents.

He spent about a week guarding one of the few open gas stations, controlling incoming traffic, and keeping order.

“I had this desire to prove myself that I had the guts to join the army and potentially sacrifice my life for the country I love (and wanted to get back to). I guess many men feel the same way at the time of war.”

Then the unit was rotated and Max joined one of his comrades who was evacuating his family to western Ukraine and Poland a few days later.

Max’s new acquaintance had lost his job a few months before and the family ran out of money a week into the war.

So, Max decided to support them at least financially.

Max was lucky to have good and caring friends from Switzerland and Germany who were eager to help.

They decided that the best option would be to send money directly to Max’s account so that he could provide help to people in dire need whom he knew personally.

“So far, we have helped six families in need, a total of 15 people, and the army. It might not be much, but it’s quality help that provides a sufficient amount of money for a month or two.”

Currently, Max is with his family. He believes that the most important thing he can do right now is support them. He continues working for SE Ranking from his home office.

Max will continue working for SE Ranking, and would love to see everybody back at the office after his colleagues return home when the war ends.

He hopes the war ends before summertime to start new hobbies: canoeing and rowing.

He dreams of rediscovering Ukraine and its beautiful rivers with his friends on camping and canoeing trips.

Advertisement

Max also plans to start voice actor training because he likes listening to audiobooks and has a suitable voice. He had planned to start training on the 6th of March.

Max confesses that he misses small things from his life before, such as going to the movies with friends, having a coriander omelet for breakfast, exercising at the gym, and having a long hot shower.

While the future remains unclear, he believes he’ll be able to fulfill his dreams, from buying a car and going on a road trip with his friends to starting a family.

And he believes that all his dreams can come true here, in Ukraine.

Building A Strong Community Of Marketing Heroes For Mutual Support

Yurii Lazaruk, is the founder of multiple well-known Ukrainian SEO communities, such as SEO Club UA, SalesHero, CPC Real Talk, and Marketing Club UA, and a community development expert.

Before the war started, he used his communities for connecting Ukrainian experts. Yurii helped them share experiences and get notable career growth.

After the first day of the war, Yurii set all his earlier initiatives aside. He decided to unite all of the active members of his numerous communities into one group called Ukrainian Hero Help.

The goal of the new community was to bring together Ukrainian SEO people to support each other, share vital information, and help the army and the entire country.

Yurii himself needed assistance finding a job to support his family.

And he found one thanks to David Spinks, a co-founder of CMX, the world’s largest network for community professionals.

Yurii now works as a part-time consultant, providing guidance on community development to Cultivate, an AI-powered coaching platform.

Yurii appreciates the opportunity to use his skills to make U.S. communities thrive.

But since it is not a full-time job, he is still looking for more opportunities.

Advertisement

Yurii is also trying to help his fellow community members by collecting requests from SEO, PPC, marketing, and sales experts, and finding them jobs with the help of international experts communities and great people within them.

So, if by any chance you are currently looking for a digital marketing specialist and are willing to help Ukrainians, you can contact Yurii, who will happily share contacts with you.

All Yurii dreams of is for the war to be over.

He aspires to create an even more powerful digital community in Ukraine, find more international clients to work with, make a lot of money, and rebuild the country!

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:

Advertisement

“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:

Advertisement

“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:

“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.

Advertisement

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.

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.

Advertisement

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:

Advertisement
  • 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.

Google publishes new documentation for how to use Google Trends for search marketing

Google Search Central published new documentation on Google Trends, explaining how to use it for search marketing. This guide serves as an easy to understand introduction for newcomers and a helpful refresher for experienced search marketers and publishers.

The new guide has six sections:

  1. About Google Trends
  2. Tutorial on monitoring trends
  3. How to do keyword research with the tool
  4. How to prioritize content with Trends data
  5. How to use Google Trends for competitor research
  6. How to use Google Trends for analyzing brand awareness and sentiment

The section about monitoring trends advises there are two kinds of rising trends, general and specific trends, which can be useful for developing content to publish on a site.

Using the Explore tool, you can leave the search box empty and view the current rising trends worldwide or use a drop down menu to focus on trends in a specific country. Users can further filter rising trends by time periods, categories and the type of search. The results show rising trends by topic and by keywords.

To search for specific trends users just need to enter the specific queries and then filter them by country, time, categories and type of search.

The section called Content Calendar describes how to use Google Trends to understand which content topics to prioritize.

Google explains:

“Google Trends can be helpful not only to get ideas on what to write, but also to prioritize when to publish it. To help you better prioritize which topics to focus on, try to find seasonal trends in the data. With that information, you can plan ahead to have high quality content available on your site a little before people are searching for it, so that when they do, your content is ready for them.”

All the best things about Ahrefs Evolve 2024

Hey all, I’m Rebekah and I am your Chosen One to “do a blog post for Ahrefs Evolve 2024”.

What does that entail exactly? I don’t know. In fact, Sam Oh asked me yesterday what the title of this post would be. “Is it like…Ahrefs Evolve 2024: Recap of day 1 and day 2…?” 

Even as I nodded, I couldn’t get over how absolutely boring that sounded. So I’m going to do THIS instead: a curation of all the best things YOU loved about Ahrefs’ first conference, lifted directly from X.

Let’s go!
