Click-through to organic results is reported to drop meaningfully when an AI Overview appears for a query — but the specific percentage circulating varies by study and population, for exactly the reasons documented in the provenance audit. This page states what's actually measured, qualified by population, rather than restating a bare number.
Headline numbers
of AI Overview citations come from Google's top-10 pages, down from ~76% a year earlier — the clearest, best-sourced trend in this category.
Why CTR is hard to measure honestly here
Most CTR figures in this space blend at least two different things. One: does a page still get clicked when it's also cited inside the AI answer? Two: does the page get clicked at all when an AI answer exists and the page didn't make it into the citation? These are different outcomes with different implications. Aggregate "CTR dropped by X%" figures rarely specify which one they describe.
The four outcomes a single "CTR" number blends
| Cited in AI answer? | Query has AI answer? | What "CTR" means here |
|---|---|---|
| Yes | Yes | Does being cited still drive a click, or does the citation itself satisfy the user? |
| No | Yes | Does a page lose clicks simply because an AI answer exists, even without being cited at all? |
| Yes | No | The classic baseline — a normal organic click with no AI answer present. |
| No | No | Also the classic baseline — not ranked, not cited, no AI answer involved. |
A single headline "CTR dropped 40%" figure almost never specifies which of the top two rows it's actually describing. A site owner's response to each is completely different, though. The first is a citation-value question: is being cited still worth something, even without a click? The second is a pure-loss question: a page that used to get organic clicks now gets fewer, for a reason unrelated to its own ranking quality.
Citation position and clicks
Does being cited earlier or more prominently within an AI answer drive more clicks than being cited later? That's the AI-search analog of classic SERP position. It's an intuitive hypothesis. But no rigorous public measurement of it exists that we could locate. Hypothesis pending direct study.
The classic-SEO CTR curve, as a point of contrast
Classic SEO has a well-documented, widely replicated finding here. Click-through rate drops sharply and predictably as ranking position moves from #1 down through the results page. Many independent studies have produced broadly similar curve shapes, over many years.
That maturity is exactly what AI-search CTR measurement currently lacks. No comparably rigorous, independently replicated curve exists yet for citation position within a generative answer. Does an equivalent, similarly steep curve exist for AI citation position? Or does the underlying dynamic, users reading a synthesized answer rather than scanning a ranked list, behave fundamentally differently? That's a genuinely interesting open question. This field hasn't answered it yet with the rigor classic SEO eventually achieved for its own ranking curve.
Most AI-search CTR figures blend two different outcomes: 'clicked despite being cited' and 'clicked because not cited at all.' Different questions, routinely reported as one number.

How to measure your own CTR impact
Filter Search Console data to queries you know trigger AI Overviews. Use the AI Overview Exposure Checker to find them. Then compare click-through on those specific queries against a comparable set that doesn't trigger one. A first-party comparison is more reliable for your own site than any aggregate external figure.
A worked example of the segmentation
Here's how, concretely. Export Search Console query-level data for the trailing 90 days. Tag each query as "AI-Overview-triggering" or not, using the checker tool above, or manual spot-checks for your highest volume queries. Within the AI-Overview-triggering group, split further by whether your page appears among the AI Overview's citations for that query.
You now have three groups: cited-and-triggered, not-cited-but-triggered, and a non-triggering baseline. Comparing CTR across all three gives a genuinely diagnostic picture. A meaningful gap between the first two groups suggests citation itself still carries real click value. A similar drop across both, relative to the baseline, suggests the mere presence of an AI Overview reduces clicks regardless of citation status. A single blended average across all AI-Overview-triggering queries, without this split, would hide exactly this distinction.
What to actually do about a real drop
If your own segmented data shows a genuine loss, two responses are worth trying before assuming nothing can be done. First, check whether your page is cited at all for the query. An uncited page facing an AI Overview has the weakest position of anyone in the table above, so getting cited is the first fix to try.
Second, look at what the page still offers beyond the answer already summarized in the AI Overview. A page that only restates the same short answer gives a reader no reason to click through. A page that adds a calculator, a comparison table, or a deeper worked example gives them one.
Verification status
The one strong figure here is the AIO rank-overlap trend — Traceable . Bare "CTR dropped by X%" claims are treated as Broken chain as a category until a population-qualified, disclosed-method version exists.
