How Google AI Overviews affect SEO
The impact is uneven — informational queries lose clicks, transactional queries are largely unaffected — so the response should be segment-specific, not sitewide.
AI Overviews changed the economics of ranking for some queries and left others essentially untouched. This article sets out where the impact actually lands, how to measure it on your own site, and what a proportionate response looks like.
The impact is uneven
The most important thing to understand is that AI Overviews do not appear uniformly. They are far more common on informational queries — definitions, explanations, how-to questions — and much less common on transactional, navigational, and local queries. They also appear inconsistently for the same query over time.
This means sitewide statements about traffic impact are close to useless. A site whose traffic comes from informational content is affected heavily. A site whose traffic comes from product and comparison queries may see very little change. The only way to know which you are is to measure your own query mix.
What happens when an overview appears
Three effects are consistently observed.
Organic results move down the page, so even position one sits below the overview. Click-through rate for every position on that query falls as a result.
Some queries resolve entirely, producing no click at all. This is concentrated in simple factual and definitional questions.
Cited sources gain some visibility from the citation itself, which partially offsets the position loss for those specific sources but does not fully compensate for it.
The net effect for most sites is fewer clicks on informational queries, with the loss concentrated in the simplest questions.
How to measure your exposure
- Export your top queries from Search Console with impressions, clicks, and click-through rate.
- Classify them by intent — informational, commercial investigation, transactional, navigational.
- Check which of the top queries currently trigger an overview, sampling manually or with a rank tracker that reports it.
- Compare click-through rate trends on triggering versus non-triggering queries over the past year, which isolates the overview effect from general seasonality.
- Calculate what share of your total organic clicks sits on triggering informational queries. That is your actual exposure.
A proportionate response
By segment, rather than sitewide
- Simple informational queries that now resolve completely. Accept that traffic is gone and shift the goal to citation and brand presence. Keep the content — being the cited source still shapes perception — but stop measuring it on sessions.
- Complex informational queries. These still send clicks because the overview cannot cover the whole answer. Compete by being genuinely deeper than an overview can be, and structure so you are also cited.
- Commercial investigation queries. Comparison and evaluation content is where the commercial value has concentrated. Invest here.
- Transactional and navigational queries. Largely unaffected. Do not let overview anxiety divert resources from them.
- Un-summarisable formats. Tools, calculators, and interactive resources still require the visit. These have become relatively more valuable.
What not to do
Do not block Google from your content to avoid being summarised. You lose the ranking along with the overview, which is strictly worse.
Do not abandon informational content. It is doing brand work, feeding your topical authority, and being cited — it just is not delivering the sessions it used to.
Do not restructure the entire site in response. The affected set is usually a minority of queries, and a targeted response is both cheaper and more effective.
The longer view
The direction of travel is toward more answers being resolved in the results page and in assistants. Planning on that basis means gradually shifting how content is justified — from traffic to presence — and building more of what cannot be summarised. Teams that started that shift early found it far less disruptive than those that treated each change as an emergency.
Common questions about AI Overviews and SEO
- How much traffic will I lose? It depends almost entirely on your query mix. Compute the share of your organic clicks sitting on informational queries that now trigger an overview — that is your actual exposure, and it is usually smaller and more concentrated than feared.
- Does being cited in an overview make up for the lost click? Partly. Citation provides some visibility and brand benefit, but it does not fully offset the position loss for informational queries. Treat it as mitigation rather than compensation.
- Should I block Google to avoid being summarised? No. Googlebot serves both overviews and ordinary rankings, so blocking costs you the ranking too. That is strictly worse.
- Which content types are safest? Anything that cannot be summarised — tools, calculators, interactive resources, and content requiring your product to be useful. These have become relatively more valuable.
- Are AI Overviews going to expand? The direction of travel is toward more answers being resolved in place. Planning on that basis, by gradually shifting how content is justified, is far less disruptive than treating each change as an emergency.
- Should I restructure my whole site? No. The affected set is usually a minority of queries. A targeted response to the identified pages is cheaper and more effective.
Tip: run the exposure calculation before the next planning cycle and put a single number on it — the share of organic clicks sitting on queries that now trigger an overview. It converts an anxious conversation into a scoped problem, and it is usually smaller than the team feared and concentrated in fewer pages than expected.
