In a dataset of 15, 000 triggers, we discovered that– usually– only 12 % of web links cited by ChatGPT, Gemini, and Copilot show up in Google’s top 10 results for the exact same prompt.
Perplexity is the outlier: virtually 1 in 3 of its citations indicate pages that rank in the leading 10 for the target query.
We assessed four AI assistants– ChatGPT, Gemini, Copilot, and Perplexity– to measure exactly how frequently the URLs they point out or reference overlap with what Google or Bing ranks for the very same query.
On average, the citation overlap between AI assistants and Google and Bing’s leading 10 stands at 11 %.
((Google AI overlap complete + Bing AI overlap overall)/ 10 = 10 96 %
Additionally down, we take a look at this damaged down by private search engine.
Utilizing data from Ahrefs Brand Radar , our data scientist, Xibeijia Guan , searched 15, 000 long-tail inquiries in Google and Bing, then asked those very same questions to AI aides.
Instance inquiries consisted of:
- “Just how much does it cost to set up a safety electronic camera?”
- “Exactly how to obtain sufficient healthy protein when you can not eat dairy?”
- “What is the most inexpensive full comprehensive insurance policy?”
- ¿ Cuál es el mejor suplemento para la recuperación muscle?”
Xibeijia after that drew out every noticeable citation returned for each and every concern across both search and AI indices.
In the search dataset, she tape-recorded the ranking placements of the pointed out Links– then classified them based on whether they showed up in the top 10, or top 100 results.
The AI aides examined include ChatGPT (both in-text citations and bottom-of-response recommendations), Gemini, Copilot, and Perplexity.
According to research accomplished by our data researcher, Xibeijia Guan , simply 12 % of citations in AI assistants likewise rank in Google’s top 10, generally.
(( 28 6 + 8 + 6 1 + 8 6 + 8 2/ 5 = 11 9 %
80 % of those citations do not place throughout Google for the initial inquiry– 80 % is essentially the average of all the “red” columns in the chart above.
The overlap between AI and search citations is smaller than we expected, however we have a number of concepts regarding why that may be.
We’ll get into them a little later on.
Perplexity straightens closest to Google
Perplexity is an AI aide that was essentially constructed to mention — its goal is to sustain nearly every declaration with a source.
Perplexity is the world’s first response engine. It looks the internet in actual time to provide quick, clear response to any type of concern– with resources and citations included … Every response includes clickable citations, making it very easy to confirm the details and dig much deeper if you desire.

ChatGPT and Gemini, on the other hand, don’t constantly link out.
Their citation process is significantly query-dependent, and their inner systems cause searches based on different criteria.
ChatGPT, as an example, appears to utilize something called the sonic classifier — if the timely “possibility” exceeds a certain threshold (i.e. if the response is much less easy to “forecast” based upon training data), then ChatGPT will certainly perform an internet search.
Perplexity consistently favors material that rates well in Google, with 28 6 % of its mentioned Links landing in the leading 10
For the other AI aides, that number hovers around 8 %– and greater than 80 % of their citations originate from pages that do not place in all for the target query.
Because Perplexity focuses heavily on citations, it appears rational that its results would align closely with Google’s.
Yet, unlike Gemini and various other AI aides, Perplexity does not draw on Google or Bing’s index. Actually, it has its very own search index, based upon its spider: perplexitybot
AI assistants– even those that make use of Google and Bing– show up to quiz search indexes in a basically various method. This describes why we’re seeing very little crossover.
When gauging against Bing results, overlap stays reduced in the leading 10– striking roughly 10 % usually.
(( 16 6 + 14 + 8 1 + 8 1 + 3 3/ 5 = 10 02 %
Copilot climbs to the top of the list, which is to be expected considering that it is a Microsoft-owned item that draws on Bing search results when producing its feedbacks.
Perplexity still stays one of the most SEO-aligned AI assistants, while ChatGPT and Gemini reveal the least overlap.
This study improves our earlier research right into just how usually upper-level web pages get cited in Google’s AI Overviews.
More analysis:
In those researches, we discovered a modest positive relationship between Google rankings and citations in AI Overviews, with 76 % of pointed out Links originating from web pages in the top 10
Based on the data, it seems as if AI Overviews feature like an extension of traditional search– emerging outcomes that mainly reflect the SERP.
In other words, AI Overviews adhere to the SERPs– AI aides do not.
Also the assistants developed by Google aren’t carefully straightened with Google’s SERPs.
There are plainly various other factors influencing what obtains cited, past simply search positions.
Our information reveals that the URLs pointed out by AI assistants rarely match what Google and Bing ranks.
Most of the times, they don’t appear in the top 10 for the target motivate– usually, they aren’t in the top 100 at all.
This is because AI aides do not rate results in similarly search engines do.
As opposed to processing just one user question when choosing what to point out, they tend to get web pages based upon several variations of that question– a technique known as” inquiry fan-out ”
These variations after that get combined making use of techniques like Reciprocatory Ranking Blend ( RRF , where the web pages that show up consistently are favored a lot more.
For instance, a web page that places around # 6 for “exactly how to descale a coffee machine,” “cleansing a Nespresso machine,” and “get rid of limescale from coffee maker” could be mentioned over one that places # 1 for just one of those.
In fact, it’s possible that AI assistants may never ever look for the actual punctual that the individual inputs– rather it simply functions as a driver for various other fan-out questions.
This is why eventual citations will not constantly rank for the original punctual.
Customization can additionally contribute: the precise same search inquiry run through AI can bring about entirely different citations, as a result of factors like the user’s prompt or discussion background.
Every one of this may explain why AI citations don’t constantly mirror the SERPs.
Tip
You can maximize for multiple, long-tail query variations utilizing Moms and dad Topics in Ahrefs Search Phrase Traveler
Just look a key words, head to the Matching Terms or Related Terms report, and take a look at the Moms and dad Topics on the left, or strike the Collections by Moms And Dad Topic tab.
After that hit the Questions tab for long-tail queries to target in your material …
And to see just how much possession you have over existing long-tail query permutations, add a Target filter for your domain.
Current tests by Aleksis Rylko suggests that SearchGPT citations carefully resemble Google citations.
Rylko believes ChatGPT may currently quietly draw from Google’s search index.
Aleyda Solís corroborated this — she uncovered that ChatGPT uses Google as a contingency when Bing web pages are inaccessible.
These findings came as a shock to many, due to the fact that ChatGPT’s integrated service provider is Bing.
From our very own dataset, we aren’t seeing much differentiation in how ChatGPT surfaces both Google and Bing results.
| Google (leading 10 | Bing (leading 10 | Google (top 100 | Bing (top 100 | |
|---|---|---|---|---|
| ChatGPT (in-text citations) | 8 00 % | 8 10 % | 8 80 % | 5 00 % |
| ChatGPT (recommendations) | 6 10 % | 8 10 % | 9 20 % | 5 20 % |
That said, we accumulated this information in very early July, so results might have changed– specifically considered that OpenAI is planning to launch its AI-first web browser , and possibly also develop its own search index, passing the current memo leakage
We’ll be doing additional research to study any citation changes.
Finishing up
From our research study, it seems that rating well does assist, yet not always for the questions you may think you would certainly need to place well for.
We’ll keep researching citation overlap in typical search and AI to see if anything changes.
In the meanwhile, maximizing for question variants, constructing subject clusters, and “possessing the entity” appears to be the way to go if you are hoping to get cited in AI.
