img-semblog

img-semblog

Earlier successful 2025, AI Overviews mostly appeared for long-tail informational queries—not high-volume commercialized aliases transactional keywords. This was accordant pinch really Google antecedently rolled our featured snippets and People Also Ask. 

So, the mobility is: was Google conscionable testing AI Overviews successful low-risk areas earlier expanding them to much queries?

We analyzed 10M+ keywords to specify really the hunt intent of queries that trigger an AI Overview has changed complete clip for clues.

Search Intent of Keywords That Trigger an AI Overview

The information shows that AI Overviews are slow but surely starting to target lower-funnel searches.

img-semblog

We’re seeing the nett formed by AI Overviews widen. The typical characteristic is now increasing crossed much types of keywords, whether they’re branded, navigational, aliases commercialized successful nature

Length of Queries that Trigger AI Overviews

We analyzed the structure and length of keywords that trigger AI Overviews and those that don’t trigger AI Overviews and saw immoderate notable differences.

img-semblog

Keywords that trigger AI Overviews thin to beryllium longer and much specific. 

These kinds of queries person been the cornerstone of astir SEO contented strategies for years. Now, brands person to compete against AI Overviews to gain attention—and clicks—in SERPs.

Difficulty, CPC, and Volume of Keywords that Trigger AI Overviews

Next, we evaluated 3 main keyword metrics for position that trigger AI Overviews compared to position that don’t trigger AI Overviews.

img-semblog

AI Overviews are showing up astir often connected low-CPC, low-volume queries—with astir 60% of keywords having 100 aliases less monthly searches. And a important share—nearly 60%—falling into the 21–60 Keyword Difficulty range.

SERP Feature Overlap pinch AI Overviews

We adjacent examined which features astir often beryllium adjacent to AI Overviews successful SERPs. In March, this is what we saw:

img-semblog

Many of the astir salient SERP features from March are nary longer seen arsenic often pinch AIOs. 

Notably, we don’t spot integrated videos arsenic overmuch (although video carousels grew). Featured snippets, image carousels, and integrated reviews are each now seen little often erstwhile an AIO appears. 

img-semblog

Related searches (95.32%) and People Also Ask (90.03%) are virtually guaranteed to look alongside an AI Overview. Also salient are video carousels and chat and forum blocks. 

Perhaps the astir important penetration is the accrued beingness of Google Ads. When this investigation was first conducted successful March 2025, ads were seen very seldom connected the aforesaid SERP arsenic an AI Overview.

Now, Google Ads appearing astatine the bottommost occurs connected 25% of AIO SERPs. That was little than 1% successful March.

What This Tells Us

  • AI Overviews are being layered connected apical of existing formats alternatively than replacing them—at slightest for now
  • Video carousels and chat and forum blocks typically characteristic YouTube and Reddit, truthful having a marque beingness connected those platforms could go much important for hunt visibility

To understand causality, we besides tracked a group of keywords that did not trigger AI Overviews successful May but did successful October. This allowed america to straight comparison zero-click behaviour earlier and aft an AI Overview was introduced for the aforesaid keyword.

img-semblog

Keywords that trigger AI Overviews do thin to person higher zero-click rates connected average, but this whitethorn bespeak that those position often person informational intent alternatively than indicating causation. 

img-semblog

Although keywords pinch AI Overviews person higher zero-click rates, the complaint isn’t rising. In fact, it’s decreased steadily since January. This challenges the presumption that AI Overviews ever trim clicks and points to a much analyzable relationship betwixt query type, personification intent, and really AI answers are delivered. 

The simplification successful zero-click rates is besides apt related to the maturation of AI Overviews among transactional and navigational searches.

When we analyzed the aforesaid keywords earlier and aft they started showing AI Overviews, we recovered the zero-click complaint decreased from 33.75% to 31.53%. 

That suggests AI Overviews don’t automatically summation zero-click behavior.Maybe the reality is that these searches were already improbable to extremity successful a click.

Health and People & Society knowledgeable the top decreases successful stock of AI Overviews.

The deficiency of maturation successful these areas is apt owed to the truth that Google tin already fulfill a batch of this request pinch specialized, high-utility SERP features, specified arsenic section packs and ads.
