Google’s AI Overviews now appear for a significant share of informational and commercial queries. The organic position a page holds has changed in meaning. A #1 ranking that surfaces an AI Overview above it sends less traffic than the same ranking did 18 months ago. That gap is measurable, and most SEO reporting does not account for it.
The practical question is not whether AI Overviews exist. It is how they are affecting organic CTR for specific queries, pages, and site categories — and what SEOs should report instead.
Key takeaways
- AI Overviews typically reduce organic CTR by 20–40% for informational queries where they appear. The effect varies by query type and position.
- The #1 position still matters, but less than before. AI Overviews can appear above position 1, pushing the first organic result below the fold.
- Standard Search Console data overstates organic traffic potential once AI Overviews are present. Filter by query type to get an accurate read.
- Track AI Overview impressions separately from traditional organic impressions. The two behave differently and compete for the same real estate.
- Report adjusted CTR, not raw CTR. Subtract AI Overview share from the organic pool to get a real traffic projection.
What the shift actually looks like in the data
The dynamic is straightforward in practice. When an AI Overview appears for a query, Google shows:
- The AI Overview panel (typically 400–800px of vertical space)
- Two to three organic links above the fold (on desktop)
- The remaining organic results below
On mobile the effect is more severe. An AI Overview can push the first organic result past the bottom of the viewport before a user scrolls.
The sites most affected are informational publishers, How-to content, product-category pages with comparison intent, and any page where Google can generate a satisfactory answer from structured content and internal citations.
The sites least affected are those where the query has high commercial intent, requires a specific transaction, or demands a location-specific result that AI Overviews do not handle well.
How to measure the impact using Search Console
Open Search Console and apply two filters to get an honest read:
Filter 1: Queries with AI Overviews present
Search Console does not natively label which queries trigger AI Overviews, but you can approximate the effect by segmenting query intent. Queries where the top results are predominantly informational — definitions, explanations, comparisons, how-tos — are the ones most likely to surface AI Overviews in 2026.
Separate these from transactional and navigational queries. The CTR for informational queries will be structurally lower.
Filter 2: Position versus impression share
Look at average position alongside impression share. A query with an average position of 1.5 and a 30% impression share suggests AI Overviews are absorbing the remaining 70% of impressions that position 1 used to capture.
The formula for adjusted organic CTR:
Adjusted Organic CTR = (Clicks) / (Impressions - AI Overview-eligible Impressions)To estimate AI Overview-eligible impressions, reduce total impressions for informational queries by 40–60% as a starting assumption, then calibrate against your own ranking changes after known AI Overview launches.
The CTR by position table for 2026
The classic position-based CTR curve has shifted. In 2024, position 1 averaged around 27% CTR on desktop for competitive commercial queries. In 2026, with AI Overviews active:
| Position | Informational query CTR | Commercial query CTR |
|---|---|---|
| 1 | 8–14% | 20–28% |
| 2 | 4–8% | 12–18% |
| 3 | 3–5% | 8–12% |
| 4–10 | 1–3% | 3–7% |
The commercial query numbers are closer to the historical baseline. The informational query numbers are materially lower — and the gap widens for queries where AI Overviews include inline citations to specific sections of your page.
What SEOs get wrong in reporting
The most common error is reporting raw organic CTR as a health metric. A 15% CTR on informational queries is not a problem — it is the new normal for queries where AI Overviews appear. Reporting it as a decline from a previous 28% creates false urgency.
The second error is conflating AI Overview citations with organic traffic. When Perplexity or ChatGPT cites your page inside an AI answer, it generates a referral. That referral appears in analytics as Direct or as a named referrer depending on the platform. Track these separately from organic sessions — they have different conversion profiles.
The third error is measuring only clicks, not shared impressions. If an AI Overview cites your page but sends zero clicks, that citation has value for brand visibility but not for the metric most SEO reports track. Distinguish between citation traffic and click traffic.
What to report instead of raw CTR
Report three metrics for a complete picture:
1. Organic sessions excluding AI Overview-eligible queries Segment your analytics by query intent and report transactional + navigational organic sessions separately from informational ones. The two pools have different baseline CTRs.
2. AI citation referrals Track sessions from AI search platforms as a distinct channel. This includes referrals from chat.openai.com, perplexity.ai, claude.ai, and any Gemini-surface referrals. Set up a custom channel group for AI search.
3. Adjusted organic CTR for informational content Take Search Console clicks and impressions for informational queries, subtract an estimated AI Overview share, and calculate the adjusted CTR. This is the number that actually reflects how well your pages perform in traditional organic results.
The adjusted CTR is the metric to optimize. If your adjusted CTR is declining, the content or its structured signals need attention. If the raw CTR is declining because AI Overviews are growing, that is a SERP change, not an SEO problem.
How to audit which pages are most affected
Run this query in Search Console for your top 50 pages by impressions:
- Export page-level data for the last 90 days
- Flag pages where average position is 1–5 and CTR is below 10%
- Cross-reference those pages against the query report
- Classify the queries triggering those impressions as informational or commercial
Pages in position 1–5 with sub-10% CTR on informational queries are your AI Overview exposure points. The action depends on the page type:
- How-to and definition pages: Add more scannable structure. AI Overviews cite pages with clear, concise answers. If your page buries the answer in a 1,200-word narrative, the AI Overview pulls the wrong snippet.
- Comparison pages: Add comparison tables. AI Overviews pull table data for “X versus Y” queries.
- Product category pages: Add FAQ schema and FAQ sections. AI Overviews surface these for commercial investigation queries.
The practical workflow
Run this audit quarterly:
- Pull Search Console data for top 100 pages by impressions
- Segment queries into informational, commercial, navigational
- Calculate adjusted CTR for informational bucket
- Flag pages where adjusted CTR has declined more than 15% quarter-over-quarter
- Audit content structure on affected pages — specifically the first 200 words, headings, and schema
- Track AI citation referrals in analytics as a separate channel
The quarterly cadence matters because Google expands AI Overview eligibility to new query types regularly. A page that was safe from AI Overview competition last quarter can be affected this quarter.
Frequently asked questions
Do AI Overviews always reduce organic CTR?
Not always. AI Overviews appear most consistently for informational queries with clear factual answers. Commercial transactional queries, local queries, and queries with high location specificity are less affected. The CTR impact is concentrated in informational content.
Can you rank in AI Overviews without structured data?
Yes, but structured data makes it more likely. FAQ schema, HowTo schema, and well-organized heading structures are the most cited signals in AI Overviews. Pages that answer a specific question in the first paragraph and use descriptive headings get picked up more consistently.
Should I try to suppress AI Overviews for my content?
Generally no. Being cited in an AI Overview drives visibility and brand awareness even without a click. The referral value from AI search is growing. Treat AI Overview citations as a separate discovery channel, not as competition for organic clicks.
How do I track AI Overview performance in Search Console?
Search Console does not yet provide a dedicated AI Overview performance report. Use query-type segmentation as a proxy: filter for informational queries, monitor CTR trends per page, and cross-reference with known AI Overview expansions from Google’s official announcements.
Does appearing in an AI Overview help or hurt SEO?
It depends on the metric. For visibility and brand discovery, AI Overview citations are positive. For direct organic CTR on informational queries, they are structurally negative. Report both separately to get an honest picture.
What this means for SEO reporting in 2026
The shift is from one CTR number to a segmented model. Informational content needs its own CTR baseline. Commercial content tracks closer to historical norms. AI citation referrals are a new channel that did not exist two years ago and deserves its own row in any serious SEO report.
The practical adjustment: build the segmented model now, set the new baselines, and stop treating a declining raw CTR on informational queries as an emergency. It is a structural SERP change, not a content failure.
Use the Search Console hidden reports to find query-level data that the main Performance report does not surface, and cross-reference with the SERP Features guide to map which of your rankings are most exposed to AI Overview competition.
Run your top pages through the Core Web Vitals audit to check whether page performance is a compounding factor — slow pages are less likely to be cited in AI Overviews even when they rank well.
