Google AIO Is Ranking More Niche Specific Sites

New data from BrightEdge shows significant changes to Google AI Overviews, prioritizing topic-specific sites and a stronger focus on ecommerce ahead of the year-end shopping season.

Google Core Update And AIO

An interesting insight from the data is that there is more overlap between AIO and Google’s organic search results, that there is more agreement between the two results. Is AIO mirroring the organic search results or are the organic search results more closely aligned with AIO?

The organic search results themselves changed after the August 2024 core algorithm update and so did AIO. BrightEdge’s data offers evidence of how Google’s organic search results changed.

BrightEdge data shows:

  • The overlap of URLs cited in AI Overviews with those ranking in the top 100 increased from 37% to 41% post-update.
  • This is following Google’s August 15th Core Update.
  • The shift indicates that AI Overviews are prioritizing organic results more than before, pulling from lower-ranked results to create comprehensive responses.

BrightEdge data shows that AIO is ranking lower-ranked web pages for more precise answers. Something else to consider is that both AIO and the organic search results changed and it could be the criteria for ranking changed in a similar way for both AIO and organic, that the algorithms for both are doing something similar.

A significant characteristic of the last update is that it is showing less of the big brand sites and more of the independent niche sites. BrightEdge data shows that AIO is also ranking websites that are more precisely about a topic.

Keep reading because there’s more about that in BrightEdge’s data which could offer insights into what’s going on in the organic SERPs.

Non-Logged-In AI Overviews

Google has rolled out AI Overviews (AIO) to users that are not logged-in to Google accounts, expanding the audience for AIO to a greater amount of people. But it’s not showing across all industries. The data shows that the integration of AIO varies.

Within the context of users who are not logged in, Ecommerce search results for not logged-in users dropped in AIO is less than logged-in users by a whopping 90%.

Users that are not logged-in didn’t see AIO in the following topics:

  • Education: 21% relative decrease
  • B2B Tech: 17% relative decrease
  • Healthcare: 16% relative decrease

Although there’s a decrease in AIO shown to non-logged-in users for ecommerce queries, there is an increase in product grids that are shown to these users compared to logged-in users. BrightEdge speculates that Google is better able to target logged-in users and is thus showing product grids to them on a more precise basis than to non-logged-in users.

More Product Comparisons

BrightEdge’s data indicates that Google AIO is showing more product comparisons and visuals.

Their data shows:

  • In August, product carousels for apparel-related queries increased by 172%.
  • The use of unordered lists across industries rose by 42%.

These adjustments make AI Overviews more user-friendly by organizing complex product features and specifications for easier decision-making.

All of those features allow users to make comparisons between products by what the products look like as well as by price. A takeaway from this data is that it may be increasingly important to show original product images (if possible) and to make sure that images shown are high quality and allow users to get a good sense of the product.

Data is always important and it’s a good way to make a product listing or product review stand apart from competitors. Any information that makes improves a consumer’s decision making is valuable.

A good example is for clothing where it’s not enough to indicate that something is a size small, medium or large. Sizes are inconsistent from manufacturer to manufacturer and even within a brand’s own products. So, for clothing, it may be useful to add comparison information about actual sizes within a product line in terms of inches or metric measurement so that a consumer can make an even better choice.

Comparison between products, especially within the context of a product review, is important. One of the product review best practices (and maybe a ranking factor) that is recommended by Google is a comparison of the product being reviewed. Google’s product reviews best practices recommendation is that publishers compare a product to another product so that users can presumably make a better decision.

Google recommends:

  • “Cover comparable things to consider, or explain which might be best for certain uses or circumstances.”

According to BrightEdge:

“As the holiday shopping season approaches Google is refining AIO search results to focus on comparative content, which rose by 12% in August. AIOs prioritized product carousels with engaging imagery, which rose by 172%. Unordered lists (lists of items that are related but in no specific order, such as general searches for ‘winter boots’ or ‘iPhone cases’) also increased by 42%.”

Google AIO Rankings Are More Precise

A data point that all search marketers should be aware of is that Google is ranking more precise content in AIO in a way that might reflect on what is going on with the organic search algorithms.

BrightEdge discovered that generalist sites had massive decreases in rankings while specialists sites had increases. People like to talk about “authority sites” and what they’re usually referring to is “big brands” with a lot of money and reach. But that’s not authority, it’s just a big brand with reach.

For example, most people consider news organizations as authority sites. But who would you go to for SEO information, Search Engine Journal or big sites like the New York Times or Fox News? What the BrightEdge data shows is that AIO is making a similar consideration of what kinds of sites are actual authorities on a given topic and then showing those sites instead of a big brand site.

The obvious question is, does this have something to do with Google’s last core update in August? One of the goals of Google’s last update is to show more independent sites. If the AIO trends mirror the organic search results to a certain extent, then perhaps what Google’s algorithms are doing is identifying sites that are authoritative in a topic and showing those sites instead of a more general big brand site.

BrightEdge’s data shows that AIO rankings of generalist technology review sites dropped. TechRadar.com dropped by 47.3 and TomsGuide.com dropped by 16.4%. This trend was also seen in health related queries where the kinds of sites that AIO quotes also became more precise.

AIO showed less consumer-focused sites and blogs and began showing more sites that are precisely about health. The BrightEdge data showed that consumer news and general sites like VerywellHealth.com experienced 77.9% drop in AIO exposure and EverydayHealth.com virtually dropped out of AIO with a 95.6% decline.

Sites like MayoClinic.org experienced a 32.4% increase and citations of the U.S. Department of Health & Human Services AIO increased by +83.2%. It’s not just a trend away from consumer and general news sites, it’s a trend toward more precise rankings of expert and authoritative content.

BrightEdge noted that the following precisely-focused sites experienced increases:

  • Spine-Health.com +266.7%
  • Arthritis.org +89.5%
  • BrightEdge’s report observes:

“This demonstrates Google’s push toward more detailed, factual content in AI Overviews.”

AIO And Organic SERPs

Google has significantly increased the use of product carousels for apparel-related queries, reflecting a 172% rise. These carousels and grids allow for easier product comparisons based on visuals, pricing, and features.

AI Overviews and Google’s organic search results have more overlap than before. The reason for that may reflect a change to prioritize increasingly precise answers from sites that are authoritative for specific topics. Niche sites have gained prominence in both organic and AI Overviews while large more general sites have lost visibility.AI Overviews continues to evolve but the changes from last month indicate that there is a certain amount of agreement between what’s in the SERPs and AIO.

How Compression Can Be Used To Detect Low Quality Pages

Published

4 days ago

on

October 27, 2024

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:

“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.”
