I Analyzed 300K Keywords. Here’s What I Learned About AI Overviews

1 month ago 20

I analyzed 300K keywords to recognize what triggers AI Overviews. The results were predictable successful immoderate ways and wholly astonishing successful others.

For instance, 1 of my favourite stats (although not the favorite – you’ll person to work connected for that ) is that 99.9% of AI Overview SERPs show astatine slightest 1 different SERP feature.

In this survey I effort to nail-down the cardinal differences betwixt AIO SERPs, vs. non-AIO SERPs.

I anticipation you find it interesting!

A speedy side-by-side examination of the data

Median CPC0.350.45

  • Average search volumes are 98% little for AIO SERP vs. for non-AIO SERPs.
  • AIO keywords person 88% little Traffic Potential (TP) compared to non-AIO SERPs.
  • AIO keywords are long-tail, with a operation magnitude of 4 words vs. 2 words successful non-AIO SERPs.
  • Keyword Difficulty (KD) is little successful AIO SERPs, with a median people of 12 vs. 33 for non-AIO keywords.
  • Content requires conscionable 13 referring domains to fertile successful an AIO SERP connected average.

  • 99.9% of AIO SERPs returned astatine slightest 1 different SERP feature, with 3 showing connected average.

  • On the different hand, AIO SERPs amusement 96% less Sitelinks, 84% less Videos, and 75% less Knowledge Panels compared to non-AIO SERPs.

Why I decided to probe AI Overview keywords

According to probe from SEOClarity, AI Overviews volition root a apical 10 ranking leafage successful the SERPs 99.5% of the time.

And recent probe conscionable successful from Kevin Indig shows that 40% of URLs successful AIOs besides fertile successful positions 11-20.

It stands to crushed that the much you cognize astir ranking organically successful an AI-topped SERP, the easier it volition beryllium to look successful an existent AI Overview.

Based connected that logic, I decided to analyse 150K of the most searched keywords that make an AI Overview, vs. 150K of the astir searched keywords without an AI Overview, to find retired the cardinal attributes of AIO topped SERPs.

I’ve studied rather a fewer akin metrics to Flow Agency’s research of 5K HR and Workforce Management AIO Keywords carried retired by the awesome Helene Jelenc backmost successful July—which besides utilized Ahrefs—so if you’ve work that study, you’ll beryllium acquainted with this data.

Ahrefs present tracks AI Overviews

Ahrefs has besides conscionable precocious released 2 awesome caller features successful Keywords Explorer which motivated maine to bash this analysis:

The AI Overview SERP Feature filter, which returns each keyword that generates an AI Overview successful the SERPs…

Ahrefs AI Overview filter successful  Keywwords Explorer

And the Intents filter…

Now, without further ado, present are my 5 apical findings from the research:

1. AI Overviews populate for debased volume, long-tail keywords

AI Overviews predominantly look for low-volume, long-tail keywords.

Even the astir searched AIO keywords aren’t driving important volume, receiving an mean of lone 150 searches per month—98% little than their non-AIO counterparts (29K).

Moreover, AIO SERPs show 88% little postulation potential, which represents the sum of integrated postulation that the #1 ranking leafage receives from each its ranking keywords—meaning that adjacent top-ranking pages person humble postulation compared to non-AIO SERPs.

The information confirms that AIO queries are long-tail, containing 4 words connected (median) mean vs. 2 for modular searches, which explains those postulation and measurement shortfalls.

Sidenote.

You’ve astir apt noticed that the astir communal AIO operation magnitude connected the illustration supra is 3—not 4, arsenic I said above. This is due to the fact that the illustration uses the “mode average”, oregon astir communal keyword operation length, successful bid to spot the percent breakdown. I person utilized median averages erstwhile analyzing standalone stats crossed the full dataset, since they’re little affected by utmost values oregon outliers.

Comparing operation lengths, you tin spot that the bulk of non-AIO keywords inclination towards the near of the illustration astir the little numbers, confirming their short-tail nature, portion AI Overview keywords highest astatine 3 words and are much evenly distributed crossed longer operation lengths.

AIO Overviews are designed to reply idiosyncratic questions, truthful it makes consciousness that AIO keywords are much discursive, and longer-tail.

I besides noticed that AIO SERPs tended to beryllium question-focused. As a speedy example, filtering for the emblematic question keyword “How” successful the AIO dataset returns 20K results, compared with lone 55 successful the non-AIO dataset.

They also, typically, displayed clearer intent. Take the eighth astir searched keyword successful the dataset, “ozempic broadside effects”, for example. The extremity of the searcher is reasonably unequivocal.

These aren’t the astir groundbreaking of insights—they’re beauteous overmuch what I expected to see—but it’s ever bully to get a mentation confirmed with real data.

Tip

AIO keywords don’t ever thrust little traffic. Here’s however to find AIO keywords with higher postulation potential.

  1. Search a wide keyword successful Keywords Explorer > Matching Terms report
  2. Select the AI Overviews successful the SERP Feature filter
  3. Sort Traffic Potential from precocious to low
  4. Find precocious postulation imaginable AIO keywords

2. AIO keywords person mean Keyword Difficulty of 12

Keyword Difficulty is simply a metric we devised to assistance you recognize however hard it is to fertile for a peculiar hunt query, based connected the fig of referring domains (RDs) earned by the Top 10 organically ranking pages.

From the data, 71% of AI Overview keywords person a Keyword Difficulty people beneath 30, with the median mean being 12—compared with a median mean of 33 for non-AI results.

Given that AIO keywords are the longer-tail, lesser searched of the two, this tracks.

Here’s an illustration keyword from the dataset with a Keyword Difficulty of 12: “Can dogs person cinnamon” (the reply is yes, successful tiny amounts, for anyone that’s wondering )

To fertile successful the SERP for galore AIO keywords successful the study, you would lone request a minimum of 13 referring domains, vs. 41 for non-AIO SERPs.

While they thrust little volumes and traffic, AIO topped SERPs necessitate less backlinks to enter into.

  5. Find applicable AI Overview generating keywords

3. Almost each AIO keywords people informational intent

As it stands, 99.2% of each AI Overview keywords are informational.

 4.0%

AI Overviews make erstwhile users are looking for details, explanations, oregon guidance, arsenic opposed to making nonstop purchases.

Commercial and transactional keywords are harder to travel by, making up little than 10% of each AIO SERPs analyzed (5.8% and 4.0% respectively).

But I expect this whitethorn increase, what with Google rolling retired ads successful AI Overviews.

When it comes to non-AIO keywords, hunt results are inactive overwhelmingly informational, but different intents look much often vs. AIO SERPs.

For instance, determination were treble the magnitude of commercialized and transactional keywords successful the non-AIO investigation vs. the AIO dataset (20% vs. 10%).

Sidenote.

Bear successful caput that the numbers don’t adhd up to 100% due to the fact that galore keywords show aggregate intents.

I was amazed to spot transactional queries showing AIO lone ~10% of the time, an summation from the 5-7% seen astatine launch. This volition surely interaction SEOs’ strategy for transactional pages. Ranking lone successful integrated hunt without respect for appearing successful AIO volition pb to missed opportunities.

4. People Also Ask and Featured Snippets are large successful AI SERPs

Remember that SEOClarity study? The amended visibility you person successful integrated hunt results, the much apt you are to triumph visibility successful AI Overviews.

And integrated hunt results don’t conscionable mean classical bluish links anymore—that overmuch we all know.

With that successful mind, I decided to analyse the prominence of 18 SERP features successful AIO hunt results.

Of the 150K AI Overview SERPs I analyzed, 99.95% returned astatine slightest 1 different SERP Feature.

In fact, each SERP returned 3 connected mean — ignoring the AI Overview itself.

If you privation to ain an AI Overview, you should see optimizing your mode into SERP Features.

Specifically, deliberation astir infusing your contented with Q&As.

The “People Also Ask” diagnostic appeared successful 80.92% of each AI Overview queries.

Featured Snippets, Thumbnails, Video Previews, and Discussions were besides prominent.

And things got adjacent much absorbing erstwhile I compared against non-AIO keywords…

There was lone a insignificant quality successful the beingness of People Also Ask for AIO and non-AIO keywords, but determination were different diagnostic contrasts that leaped retired of the data.

If you deliberation that AI Overviews are supplanting Featured Snippets, think again.

This diagnostic appears successful implicit fractional of each queries successful the dataset. It’s intrinsically tied to the AIO SERP.

This is what it looks like, for those who are unfamiliar: 

Discussions are besides acold much prevalent successful AIO SERPs astatine the clip of writing. Here’s what they look similar connected the SERP:

I’ll admit I was surprised to spot the Knowledge Panel truthful debased down the AIO illustration though, with 76% little visibility than non-AIO results.

According to Google’s authoritative documentation, it relies connected the Knowledge Graph to make AI Overviews.
