For many queries, People Also Ask boxes are observably suppressed or reduced on search results pages where an AI Overview is present, a pattern directly documented by SERP-feature tracking tools across the industry that monitor which features appear on which result pages over time. This is worth stating precisely: it’s a real, observable pattern in how SERP real estate is being allocated, not a confirmed mechanism Google has explicitly described as “AI Overviews replace PAA.” Google hasn’t published a statement saying it deliberately absorbs or eliminates PAA in favor of AI Overviews. What’s verifiable is the outcome, the two features functionally overlap in purpose (both surface related questions and their answers), and observationally, when one is present the other is frequently reduced or absent, which is consistent with SERP real estate competition between overlapping features rather than a stated design decision.
Why this pattern makes sense mechanically, without asserting a confirmed cause
People Also Ask and AI Overviews serve a genuinely overlapping function from the user’s perspective: both aim to answer related or follow-up questions directly within the search results page, without requiring the user to click through and search again. PAA does this through a list of expandable, individually-sourced question-and-answer boxes. AI Overviews do it through a synthesized summary that Google has described as being built on top of Search’s core ranking and retrieval systems, often incorporating and effectively subsuming the kind of related-question coverage PAA was designed to provide, but in a single generated block rather than a list of separate expandable items.
Given that overlap in function, it follows logically that a search results page has finite vertical space, and Google’s systems have to make some allocation decision when both a PAA box and an AI Overview would otherwise be relevant to display for the same query. The observable pattern (PAA less frequently present or reduced in prominence on AI-Overview-present SERPs) is consistent with this space-competition dynamic. But “consistent with” is different from “confirmed by Google as the specific mechanism,” and it’s important not to collapse that distinction, since no direct Google statement describes this as an intentional feature-replacement decision with a stated rule or percentage.
What shouldn’t be asserted
Avoid citing any specific percentage of PAA suppression rate, any claim like “PAA appears 40% less often when an AI Overview is present,” without directly sourcing it to a specific, currently-verifiable third-party study, and even then, treating it explicitly as a third-party observational estimate rather than a Google-confirmed figure. This is a fast-moving area of SERP layout behavior that changes as Google continues to iterate on both features, and specific numbers from any point in time risk becoming stale or being presented with more certainty than the underlying data supports. The accurate, durable claim is the directional pattern (observable overlap and reduction), not a specific quantified rate.
A hypothetical illustration of the shift showing up in tracked data
Hypothetically, imagine a home-improvement content site, “Millbrook Home Journal,” that has historically tracked a set of several hundred query terms where its articles regularly appeared in PAA boxes. A quarterly SERP-feature review could plausibly show that for a meaningful share of those same queries, an AI Overview now appears where a PAA box previously did, and PAA presence for that subset has dropped, without any change in the site’s actual ranking position for the underlying queries. Treating that shift as a prompt to check whether the site’s content is being cited or referenced within the AI Overview itself, rather than continuing to optimize narrowly for PAA inclusion on a feature that’s visibly receding for that query set, would be the more useful response to notice in the data.
Practical implication for practitioners
If your tracked queries have historically generated meaningful traffic or visibility value from PAA presence (either your content being featured in PAA boxes, or PAA-driven query expansion informing your content strategy), it’s worth directly monitoring, via your own SERP tracking or manual spot-checks, whether AI Overviews are increasingly present for those same queries and whether PAA presence has correspondingly declined for your specific tracked query set. This is more reliable than assuming a general industry pattern applies uniformly to your exact query mix, since AI Overview rollout and PAA display both vary by query type, vertical, and over time as Google continues to adjust both features.
The strategic response, to the extent one is warranted, mirrors the broader adaptation practitioners are making across the AI Overview landscape generally: treating citation or mention within an AI Overview as a related but distinct opportunity from historical PAA-box presence, since the mechanics of how content gets surfaced (or not) differ between a list of discrete Q&A snippets and a synthesized generative summary, even though both serve a related-question function from the user’s perspective. Diversifying away from dependence on any single SERP feature’s continued presence, rather than optimizing narrowly for PAA inclusion as if it were a stable, permanent fixture of the SERP, is the more durable posture given how visibly this specific feature’s prevalence is shifting.
