AI Overviews Click Decline: 58% CTR Drop and What It Means

The headline number got worse

Google's AI Overviews are taking a larger share of the clicks that once went to top-ranking pages. Ahrefs re-ran its click-through study using December 2025 data. It found that when an AI Overview appears, the average clickthrough rate for the page in position one is about 58% lower than it would otherwise be 1. Put another way, for every 100 clicks a top result might once have earned, Google now keeps roughly 58 1.

That is a sharp jump from the same firm's April 2025 measurement, which put the drop at 34.5% 2. The effect also reaches further down the page. Position two is down 50.8%, and even position ten has lost 19.4% 2. The cost is heaviest at the top, which is uncomfortable for anyone whose strategy depends on winning the number-one spot.

How the estimate is built

The 58% figure is not a raw before-and-after comparison, and the method matters. Ahrefs used the CTR decline on informational keywords without AI Overviews as a baseline trend. It then projected what CTR on AI Overview keywords would have been had the feature never launched, landing on about 0.037. The observed rate was roughly 0.0157, and the gap between the two produces the ~58% reduction 1.

The baseline itself has been falling. Ahrefs attributes that to a long run of Google features that answer queries on the results page, including the Local Pack, Top Stories and Featured Snippets 1. Zero-click search predates generative AI. AI Overviews speed up a trend that was already underway rather than starting it. The estimate is a modeled counterfactual, so treat the exact percentage as an approximation. The direction of the change is not in doubt.

Independent data points the same way

Other research broadly agrees. Pew Research found that when an AI summary is present, users click organic results about half as often: 8% of visits compared with 15% without one 2. Pew's method and sample differ from Ahrefs', which uses Search Console data across 300,000 keywords 2, yet the two arrive at similar conclusions.

The feature is also now common. AI Overviews appeared on about 48% of tracked Google queries by early 2026 24. Tyneside Marketing reports that share grew 58% in a single year 2. Colorlib reports that 68% of US Google searches ended without a click in early 2026 4. Google's position is unaffected so far. It held 89.9% of the global search market, handles more than 5 trillion searches a year, and earned $294.7 billion in advertising revenue in 2025 4. Fewer clicks for publishers has not meant less engagement for Google.

One more figure explains why AI-generated answers are likely to spread. About 15% of daily searches are queries Google has never seen before 4. Novel, long-tail questions suit synthesized answers better than a fixed list of ten links.

What the industry is doing about it

Practitioners have largely accepted the shift. In a GoodFirms survey, 76% of respondents described a move from blue links toward AI-generated answers and zero-click results 3. The same survey reports that 89% of brands appear in Google AI Overviews for their target queries 3. That finding deserves some caution, because self-reported visibility and measured click value are different things.

On strategy, the most common answer (54%) was content quality and intent matching 3. That means original, in-depth, well-structured material that AI systems can parse and cite, and a move away from generic content that is easy to summarize 3. Optimization aimed directly at AI search and LLMs, often labeled GEO or AEO, also appears as a distinct priority 3.

The reading

The evidence supports a clear conclusion. Ranking first is worth considerably less than it was a year ago when an AI Overview sits above it, and the penalty has grown over time 12. Some in the industry argue that being cited inside an Overview carries a meaningful click premium. That is plausible, but the data available here does not quantify it, and any specific uplift figure should be checked against first-party analytics before it shapes budgets.

More defensible conclusions follow from what is known:

• Treat the queries most exposed to AI Overviews as lower-yield traffic. Expect less from informational queries in particular.
• Invest in content that resists summarization. The goal is material an AI cannot fully replace with a paragraph.
• Measure citations and conversions directly. Blended CTR averages can hide which pages still earn clicks.

Rankings still matter. They now convert into fewer clicks than they used to, and planning should account for that.
