I analyzed 300K key phrases to grasp what triggers AI Overviews. The outcomes had been predictable in some methods and wholly shocking in others.
As an illustration, one in every of my favourite stats (though not the favourite – you’ll should learn on for that ) is that 99.9% of AI Overview SERPs show at the least one different SERP function.
On this research I try to nail-down the important thing variations between AIO SERPs, vs. non-AIO SERPs.
I hope you discover it attention-grabbing!
| Metric | AIO SERPs | Non-AIO SERPs |
|---|---|---|
| Median Key phrase Problem | 12 | 33 |
| Median Search Quantity | 500 | 29,000 |
| Median Visitors Potential | 2,200 | 18,000 |
| Median CPC | 0.35 | 0.45 |
| Median Key phrase Size | 4 | 2 |

- Common search volumes are 98% decrease for AIO SERP vs. for non-AIO SERPs.
- AIO key phrases have 88% decrease Visitors Potential (TP) in comparison with non-AIO SERPs.
- AIO key phrases are long-tail, with a phrase size of 4 phrases vs. 2 phrases in non-AIO SERPs.
- Key phrase Problem (KD) is decrease in AIO SERPs, with a median rating of 12 vs. 33 for non-AIO key phrases.
- Content material requires simply 13 referring domains to rank in an AIO SERP on common.
- Informational intent key phrases set off an AI Overview 99.2% of the time.
- AIOs solely have a ten% probability of exhibiting for business and transactional key phrases.
- 99.9% of AIO SERPs returned at the least one different SERP function, with 3 exhibiting on common.
- AIO key phrases set off 849% extra Featured Snippets and 258% extra Discussions in comparison with non-AIO queries.
- However, AIO SERPs present 96% fewer Sitelinks, 84% fewer Movies, and 75% fewer Data Panels in comparison with non-AIO SERPs.
In response to analysis from SEOClarity, AI Overviews will supply a prime 10 rating web page within the SERPs 99.5% of the time.
And recent research just in from Kevin Indig reveals that 40% of URLs in AIOs additionally rank in positions 11-20.
It stands to purpose that the extra about rating organically in an AI-topped SERP, the simpler it is going to be to look in an precise AI Overview.
Primarily based on that logic, I made a decision to investigate 150K of the most searched key phrases that generate an AI Overview, vs. 150K of essentially the most searched key phrases with out an AI Overview, to search out out the important thing attributes of AIO topped SERPs.
I’ve studied fairly just a few related metrics to Circulate Company’s research of 5K HR and Workforce Management AIO Keywords carried out by the superior Helene Jelenc again in July—which additionally used Ahrefs—so in the event you’ve learn that research, you’ll be acquainted with this information.
Ahrefs now tracks AI Overviews
Ahrefs has additionally only recently launched two superior new options in Key phrases Explorer which motivated me to do that evaluation:
The AI Overview SERP Characteristic filter, which returns each key phrase that generates an AI Overview within the SERPs…
And the Intents filter…
Now, with out additional ado, listed below are my 5 prime findings from the analysis:
AI Overviews predominantly seem for low-volume, long-tail key phrases.
Even essentially the most searched AIO key phrases aren’t driving substantial quantity, receiving a mean of solely 150 searches monthly—98% decrease than their non-AIO counterparts (29K).
Furthermore, AIO SERPs show 88% much less visitors potential, which represents the sum of natural visitors that the #1 rating web page receives from all its rating key phrases—that means that even top-ranking pages obtain modest visitors in comparison with non-AIO SERPs.
The information confirms that AIO queries are long-tail, containing 4 phrases on (median) common vs. 2 for normal searches, which explains these visitors and quantity shortfalls.
Sidenote.
You’ve most likely seen that the most typical AIO phrase size on the chart above is 3—not 4, as I stated above. It’s because the chart makes use of the “mode common”, or commonest key phrase phrase size, with the intention to see the proportion breakdown. I’ve used median averages when analyzing standalone stats throughout your entire dataset, since they’re much less affected by excessive values or outliers.
Evaluating phrase lengths, you possibly can see that almost all of non-AIO key phrases development in direction of the left of the chart across the decrease numbers, confirming their short-tail nature, whereas AI Overview key phrases peak at 3 phrases and are extra evenly distributed throughout longer phrase lengths.
AIO Overviews are designed to reply person questions, so it is smart that AIO key phrases are extra discursive, and longer-tail.
I additionally seen that AIO SERPs tended to be question-focused. As a fast instance, filtering for the everyday query key phrase “How” within the AIO dataset returns 20K outcomes, in contrast with solely 55 within the non-AIO dataset.
In addition they, usually, displayed clearer intent. Take the eighth most searched key phrase within the dataset, “ozempic unintended effects”, for instance. The purpose of the searcher is pretty unequivocal.
These aren’t essentially the most groundbreaking of insights—they’re just about what I anticipated to see—but it surely’s at all times good to get a concept confirmed with actual information.
Tip
AIO key phrases don’t at all times drive decrease visitors. Right here’s how one can discover AIO key phrases with greater visitors potential.
- Search a broad key phrase in Key phrases Explorer > Matching Phrases report
- Choose the AI Overviews within the SERP Characteristic filter
- Kind Visitors Potential from excessive to low
- Discover excessive visitors potential AIO key phrases
From the data, 71% of AI Overview keywords have a Keyword Difficulty score below 30, with the median average being 12—compared with a median average of 33 for non-AI results.
Given that AIO keywords are the longer-tail, lesser searched of the two, this tracks.
Here’s an example keyword from the dataset with a Keyword Difficulty of 12: “Can dogs have cinnamon” (the answer is yes, in small amounts, for anyone that’s wondering )
To rank in the SERP for many AIO keywords in the study, you would only need a minimum of 13 referring domains, vs. 41 for non-AIO SERPs.
While they drive lower volumes and traffic, AIO topped SERPs require fewer backlinks to enter into.
Tip
Find low difficulty AIO keyword opportunities from your competitors:
- Search your competitors’ domain in Site Explorer > Organic Keywords report
- Switch on the AI Overview SERP Feature filter
- Select “Where target ranks” to see which AI Overviews your competitors own
- Apply a maximum Keyword Difficulty filter of 50
- Find relevant AI Overview generating keywords
Because it stands, 99.2% of all AI Overview key phrases are informational.
AI Overviews generate when customers are on the lookout for particulars, explanations, or steering, versus making direct purchases.
Industrial and transactional key phrases are tougher to come back by, making up lower than 10% of all AIO SERPs analyzed (5.8% and 4.0% respectively).
However I anticipate this may increasingly enhance, what with Google rolling out ads in AI Overviews.
Relating to non-AIO key phrases, search outcomes are nonetheless overwhelmingly informational, however different intents seem extra regularly vs. AIO SERPs.
As an illustration, there have been double the quantity of business and transactional key phrases within the non-AIO evaluation vs. the AIO dataset (20% vs. 10%).
Sidenote.
Keep in mind that the numbers don’t add as much as 100% as a result of many key phrases show a number of intents.
I used to be stunned to see transactional queries exhibiting AIO solely ~10% of the time, a rise from the 5-7% seen at launch. This may definitely affect SEOs’ technique for transactional pages. Rating solely in natural search with out regard for showing in AIO will result in missed alternatives.

Do not forget that SEOClarity research? The higher visibility you will have in natural search outcomes, the extra doubtless you’re to win visibility in AI Overviews.
And natural search outcomes don’t simply imply basic blue hyperlinks anymore—that a lot all of us know.
With that in thoughts, I made a decision to investigate the prominence of 18 SERP options in AIO search outcomes.
Of the 150K AI Overview SERPs I analyzed, 99.95% returned at the least one different SERP Characteristic.
In actual fact, every SERP returned 3 on common — ignoring the AI Overview itself.
If you wish to personal an AI Overview, you need to contemplate optimizing your means into SERP Options.
Particularly, take into consideration infusing your content material with Q&As.
The “Folks Additionally Ask” function appeared in 80.92% of all AI Overview queries.
Featured Snippets, Thumbnails, Video Previews, and Discussions had been additionally outstanding.
And issues received much more attention-grabbing after I in contrast in opposition to non-AIO key phrases…
There was solely a minor distinction within the presence of Folks Additionally Ask for AIO and non-AIO key phrases, however there have been different function contrasts that leaped out of the information.
Key phrases that set off AIOs additionally set off…
…vs. non-AIO search outcomes.
In the event you assume that AI Overviews are supplanting Featured Snippets, assume once more.
This function seems in over half of all queries within the dataset. It’s intrinsically tied to the AIO SERP.
That is what it appears to be like like, for individuals who are unfamiliar: 
Discussions are additionally way more prevalent in AIO SERPs on the time of writing. Right here’s what they appear to be on the SERP:
Google’s had a gentle spot for user-generated content material (UGC) all all through 2024, and in a latest interview with Aleyda Solis, Danny Sullivan confirmed they’ll be sticking with this technique, so it doesn’t shock me to see way more Discussions current for AIO key phrases.
I’ll admit I was stunned to see the Data Panel so low down the AIO chart although, with 76% decrease visibility than non-AIO outcomes.
In response to Google’s official documentation, it depends on the Data Graph to generate AI Overviews.
Evidently, it doesn’t want the visible Data Panel to generate AI Overview content material, and simply grabs info from the Data Graph database within the background.
Tip

- Head to the Questions tab within the Matching Phrases report

Cell visitors dominates AI Overview queries, accounting for 81% of visitors, vs. 19% for desktop.
It’s marginally much less necessary to be mobile-optimized for non-AIO queries (77% cell vs. 23% desktop), however these SERPs are nonetheless overwhelmingly mobile-first.
Your content material must be mobile-ready in the event you’re hoping to up your visibility in AIO search outcomes.

How I compiled this analysis
I ran an open search in Key phrases Explorer, utilized Ahrefs’ AI Overview SERP filter, exported the highest 150K outcomes, then analyzed the information in Google Sheets with a bit assist from ChatGPT.
Then I repeated this course of for non-AIO producing key phrases—the one distinction being that I chosen the “Not on SERP” filter in Key phrases Explorer.
Wrapping up
By specializing in academic content material, optimizing for outstanding SERP options, and getting your content material cell optimized, you’re typically extra prone to increase visibility in AIO SERPs, and possibly even declare the AI Overview by proxy.
Keep in mind it is a pretty broad dataset, provided that I’ve analyzed the most searched AIO and non-AIO queries. Metrics will certainly differ throughout area of interest key phrase classes.
I simply did a fast verify on 680 website positioning/Advertising key phrases, for instance, and AIO key phrases are overwhelmingly desktop pushed (72% for desktop vs. 28% for cell), that means cell optimization gained’t be as essential in the event you work in SaaS.
I wholly encourage you to do your individual analyses in Ahrefs on your business and/or the key phrases you care about.
Since I performed this research, Ahrefs’ Key phrases Explorer has found much more AI Overview based mostly key phrases. We’re engaged on accumulating extra information, together with the presence of hyperlinks and domains throughout the AIO, so hold your eyes peeled for that.
