AI Overview CTR Fell 61% in Q4 — But Did Clicks Actually Collapse?
AI Overview CTR for brand-cited pages dropped 61% from Q3 to Q4 2025 — but that headline number tells only half the story. A new study by digital agency Seer Interactive, covering 5.47 million queries across 53 brands, reveals that the dramatic fall in AI Overview CTR was largely driven by an explosion in impressions, not a collapse in actual clicks. Understanding the difference is critical for every SEO professional trying to make sense of Google’s AI Overview performance data in 2026.
What the Seer Interactive AI Overview CTR Data Actually Shows
Seer Interactive analysed 5.47 million queries across 53 brands throughout Q3 and Q4 2025. Their focus was AI Overview CTR — specifically for pages that were cited as sources inside Google’s AI Overviews. Here is the month-by-month breakdown:
- September 2025: 15.8 million impressions, 398,798 clicks — AI Overview CTR of 2.52%
- October 2025: 33.1 million impressions, 400,271 clicks — AI Overview CTR of 1.21%
- November 2025: 39.5 million impressions, 301,783 clicks — AI Overview CTR of 0.76%
The combined Q4 figure produces a 61% AI Overview CTR decline. However, when you break it apart month by month, two completely different forces are at work.
October vs. November: Two Very Different Stories
October: A Maths Problem, Not a Traffic Crisis
In October, impressions more than doubled — from 15.8 million to 33.1 million — while clicks barely moved, going from 398,798 to just 400,271. The AI Overview CTR fell from 2.52% to 1.21%, but this drop is almost entirely explained by rapid impression growth outpacing clicks. The pages were getting far more visibility inside AI Overviews, but those additional impressions were not converting to clicks at the same rate. This is a maths issue, not a sign of a traffic disaster.
November: A Genuine Click Decline Worth Monitoring
November is a different story. Impressions continued rising to 39.5 million, but clicks actually fell — from 400,271 down to 301,783. The AI Overview CTR dropped further to 0.76%. This is a real decline: visibility grew but traffic went down. Seer’s data does not explain why clicks fell in November specifically, and the agency openly acknowledges this gap. This is exactly why Seer recommends analysing each month separately inside Google Search Console rather than blending all of Q4 into a single figure.
What This AI Overview CTR Report Cannot Tell You
Seer is transparent about a key limitation: the report cannot determine whether October’s impression surge happened because Google expanded AI Overviews for more queries, or because brands actively earned more citations through SEO. Both explanations fit the data, and neither can be confirmed without a detailed account-level query analysis.
This ambiguity matters. If impressions grew because Google expanded where it shows AI Overviews, the data is largely noise. If they grew because a brand genuinely earned more citations, that is meaningful progress. The lesson: do not rely on aggregate AI Overview CTR metrics alone — dig into query-level data inside Search Console to understand the real driver.
How This Fits With Other AI Overview CTR Research
Seer’s findings are consistent with a growing body of research showing that AI Overview CTR is lower whenever AI Overviews appear in Google results. Key studies include:
Taken together, the evidence is clear: AI Overview CTR is lower across the board when AI Overviews appear. Seer’s contribution adds important nuance — a falling AI Overview CTR does not always mean fewer clicks, and cited pages behave very differently from uncited ones.
Other Key Findings From the Report
Citations Help — But Don’t Fully Restore Lost Traffic
Brand-cited pages receive approximately 120% more clicks per impression than uncited pages on AI Overview SERPs. However, they still lag behind pages appearing on SERPs without any AI Overview by 38%. Being cited is clearly better than being invisible, but it does not restore AI Overview CTR or traffic to pre-AI Overview levels.
Organic CTR on AI Overview SERPs Is Rising — But Cautiously
Seer reports that organic CTR on AI Overview SERPs rose from 1.3% in December 2025 to 2.4% in February 2026. This looks promising, but Seer cautions against over-interpreting it — calling it a levelling off rather than a recovery, and advising against making forecasts from just two months of data.
What Falling AI Overview CTR Means for Your SEO Strategy
Here is how to apply these findings in practice:
- Do not panic at a falling AI Overview CTR alone. Always check whether impressions grew during the same period before drawing conclusions.
- Analyse months separately in Google Search Console. Blending Q4 into one view hides very different underlying trends.
- Prioritise earning AI Overview citations. Cited pages receive 120% more clicks per impression than uncited pages on the same SERPs.
- Use query-level data to understand impression growth. Determine whether it reflects broader Google changes or genuine citation gains from your SEO.
- Track clicks, impressions, and citation coverage as three separate metrics — not a single AI Overview CTR figure.
- Industry benchmarks reflect general trends. Your own website data tells your specific story — trust both, but prioritise your own.
What to Watch in 2026
The central unresolved question is whether growing AI Overview visibility will eventually drive more clicks to cited pages — or whether cited pages will keep absorbing impressions without a proportional traffic upside.
If November’s pattern of rising impressions alongside falling clicks persists, the strategic value of being cited in AI Overviews may need to be measured as brand visibility rather than direct traffic. The early 2026 uptick in organic CTR on AI Overview SERPs is a signal worth monitoring closely over the next few months.
Conclusion: Read AI Overview CTR Data Month by Month
The Seer Interactive report makes one thing clear: AI Overview CTR metrics demand careful, month-by-month interpretation. A single 61% Q4 decline figure is alarming in isolation, but it conceals two very different stories — an October shaped by impression growth and a November shaped by a real click decline.
For SEOs, the practical message is straightforward: stop treating AI Overview CTR as a standalone success metric. Clicks, impressions, citations, and AI Overview appearance rate all need to be evaluated separately to build an accurate picture of your organic search performance in 2026.
