## Frequently Asked Questions (FAQs)

**What percentage of Google searches show AI Overviews?**AI Overviews appear on approximately 48% of all tracked search queries as of about February 2026, per BrightEdge data. Semrush measured peak prevalence at roughly 24.61% in July 2025 before a pullback to about 15.69% by November 2025, from more than 10M terms, with nearly 60% having fewer than 100 monthly searches.

Early 2026 data shows organic CTR recovering to approximately 2.4%, suggesting CTR began recovering from its late-2025 floor, per the Seer study. The trajectory varies by query type and industry vertical, so site-level outcomes depend heavily on topic mix and how well a brand has adapted its content strategy to the new SERP layout.

## Conclusion

AI Overviews reached approximately **48%** of tracked queries by about February this year, a **58%** increase over the prior 12 months, BrightEdge reports. The collected findings paint a nuanced picture with competing signals: organic CTR dropped as much as **61%** on affected queries, yet early recovery signals show CTR rebounding to approximately **2.4%**, while overall search impressions rose approximately **49%**, even as clicks fell nearly **30%** with Google at over **90%** share.

SEO professionals, digital marketers, and publishers face a search environment where AI Overviews create both threats (traffic loss for uncited sites) and opportunities (citation advantage for optimized brands). The data suggests the initial shock period may be giving way to a new equilibrium where citation visibility matters as much as traditional ranking position. Separate [LLM hallucination statistics](https://sqmagazine.co.uk/llm-hallucination-statistics/) remain a factor in AI search accuracy and trust.

These AI overview statistics show that Google’s AI-powered search is no longer experimental but rather a core product shaping how users discover content and how advertisers plan budget allocation. Google Search revenue grew **17%** year over year to **$63.07 billion**, with GenAI revenue up nearly **400%**, showing the business model is working for Google, even as publishers grapple with declining referral volumes and an uncertain outlook for organic discovery. The question for the rest of the web is whether [Google search statistics](https://sqmagazine.co.uk/google-search-statistics/) will continue to show the same volume growth, or whether alternative AI search tools will begin fragmenting the market in meaningful ways.
