The numbers are in, and they are not subtle. AI Overviews now appear on 48% of tracked Google search results, up 58% in a single year. Pew Research found that when an AI summary is present, people click on organic results roughly half as often as they do without one, dropping from 15% of visits to 8%. Ahrefs, analysing 300,000 keywords of Search Console data, measured a 58% click-through rate drop for the top-ranked page when an AI Overview appears. Whether you like the shift or not, it is already happening at scale. The question for a small business is what to do about it.

This guide pulls the most recent credible data together, explains what it actually means, and gives a short list of practical responses. No panic, no vague "embrace AI" advice.

AI Overviews are no longer an edge case

At the start of 2025, AI Overviews appeared on roughly 6 to 7% of Google searches. By February 2026, BrightEdge tracked them across 48% of industries, a 58% year on year increase. Some verticals are higher. Health, education and research queries now sit closer to 80%. The idea that a small business can wait this out is no longer realistic.

Three studies published in the second half of 2025 and early 2026 gave us the first solid data on what that scale means for click volume. The headline numbers are worth seeing in context rather than in panic.

What the three big studies actually say

Pew Research, March 2025 (900 US adults, 68,879 Google searches analysed). When an AI summary is present, users click an organic result in 8% of visits. Without one, they click in 15%. Users clicked a source cited inside the AI summary itself just 1% of the time. Source.
Seer Interactive, September 2025 (3,119 search terms across 42 organisations, 25.1 million impressions). Organic CTR when your brand is cited inside the AI Overview: 0.70%. When not cited: 0.52%. When no AIO is present: 1.45%. Being cited delivers 35% more organic clicks than not being cited. Source.
Ahrefs, December 2025 (300,000 keywords, Search Console data). Position one CTR drops 58% when an AI Overview appears, up from a 34.5% drop in April 2025. The impact thins down the page: position two is down 50.8%, and position ten is down 19.4%. Source.

The pattern across the three studies is consistent. Informational content that used to funnel clicks to the top of page one now often gets summarised in place and the page closes. Being cited in the AIO cushions the blow but does not restore the pre-AIO click volume. The single most important consequence is that visibility no longer equals traffic.

Does this mean SEO is dead?

No. The parts of SEO that rely on informational clicks are under pressure. The parts that rely on commercial and transactional intent are largely unaffected. We covered the mechanics in our guide to content types and search intent. Informational queries are where AI Overviews appear. Transactional queries, things like "book plumber newcastle" or "buy carpet cleaner gateshead", almost never trigger one, because a summary does not help someone who is ready to hire. Those searches still deliver clicks at close to pre-AIO levels.

The practical consequence is that the mix of what small businesses publish should shift. Less thin informational content. More substantial articles that are worth citing. More investment in service and location pages that serve commercial and transactional intent.

What small businesses should actually do

Five practical responses, ordered by return on effort.

Invest in AEO as insurance. The cited brand gets 35% more organic clicks than the uncited one, even inside an AI Overview. Our AEO primer explains the discipline, and the five-step practical guide walks through implementation in order.
Make informational content worth citing. Thin how-to posts lose, because AI can summarise them in a single sentence. Longer, question-structured articles with real data, named sources, and original examples win. Depth over volume.
Strengthen commercial and transactional pages. AI Overviews rarely appear for "book X", "near me" or "quote" style queries. Those searches still deliver clicks. Invest in the service and location pages that capture them, not in more blog posts.
Build owned channels. Email lists, newsletter subscribers and a genuine social presence are partly insulated from search volatility. If Google's CTR halves again next year, these channels do not move.
Measure AI visibility, not just rankings. A rising Google rank no longer guarantees rising traffic. Tracking citations in ChatGPT, Perplexity and Google AI Overviews is a new discipline. Our guide to measuring AEO covers both free and paid methods.

Common questions

What percentage of Google searches now show an AI Overview?

As of February 2026, BrightEdge tracks AI Overviews on 48% of queries across monitored industries, up 58% year on year. Other trackers place the figure above 50% globally and around 50% in the US. Certain verticals such as health, education and research trigger AI Overviews on roughly 80% of queries.

How much do AI Overviews reduce click-through rates?

The short answer is "substantially, and more at the top". Pew Research measured a drop from 15% to 8% of visits when an AI Overview is present. Ahrefs measured a 58% drop in click-through rate at position one. The impact reduces down the page, and is mostly concentrated on informational queries.

Does appearing in an AI Overview help or hurt my business?

It helps, but not as much as ranking in pre-AIO search did. Seer Interactive found that being cited inside an AI Overview delivered 35% more organic clicks than not being cited. The citation itself cushions the blow rather than restores traffic to pre-AIO levels.

Will AI Overviews eventually appear on every search?

No. AI Overviews appear when the query is best answered by combining information from several sources. That is mostly informational intent. Transactional queries ("book X", "buy X near me") and navigational queries (someone typing your brand) almost never trigger one. Commercial comparison queries are a mixed middle ground.

What should a small business prioritise in response?

Shift effort from thin blog posts to fewer, deeper articles that are worth citing. Strengthen service and location pages (commercial and transactional intent is still a high-click zone). Start tracking AI citations rather than just keyword rankings. And build at least one owned channel (email, newsletter) that is not dependent on Google's click economy.
