AI Search in Numbers: Zero-Click, AI Overviews, Market Shares

By Nils Ehrenfried · 25 August 2026 · 6 min read

Quick answer: In 2026, around 68% of all Google searches end without a click on any website; when an AI Overview appears, the click-through rate even for position 1 drops by more than half. At the same time, roughly 45% of consumers use AI assistants for local recommendations. Visibility is increasingly won inside the answer – no longer just among the links.

As of: 25 August 2026. This page collects the most reliable available numbers on AI search, each with its source, and is updated continuously.

68 out of 100 Google searches now end without a single click on a website.

This page collects the solid numbers behind that – each with a source – and answers the question that follows for a local business: where does the customer still find you, if they no longer click? From "SEO is dead" to "nothing will change", both extremes are wrong, and both can be shown wrong with the same data.

All the numbers on AI search, with sources – as of August 2026

Clicks and zero-click:

  • Around 68% of all Google searches end without a click on a website; for searches showing an AI Overview, it's roughly 83% (zero-click analysis, German).
  • When an AI Overview appears, the click-through rate of the first organic result falls from around 27% to 11% – a drop of about 59%. Basis: a SISTRIX analysis of 100 million keywords in the German Google index (data and facts on the click loss, German).
  • Roughly 20% of German search queries trigger an AI Overview – about 30% for fully phrased long-tail questions (ibid.).
  • In total, German websites are estimated to lose 265 million organic clicks per month as a result (Collective Brain analysis, German).

Usage of AI systems:

  • 71% of AI users in Germany use ChatGPT – roughly 40% of the population aged 16+ (Bitkom, spring 2026, via ahead, German).
  • AI search market shares in early 2026: ChatGPT ≈ 61%, Gemini ≈ 22%, Copilot ≈ 13%, Perplexity ≈ 6%, Claude ≈ 4% (market share overview, German).
  • Google's AI Overviews reach more than 2.5 billion people per month, according to the company (AI search statistics, German).
  • The share of web traffic referred by AI systems is still only around 1% – but growing at 130–150% per year (ibid.).

Local recommendations:

Three readings – what the numbers actually mean

1. Visibility is shifting from the click into the answer. When two-thirds of searches end without a click, what increasingly decides is what stands in the answer itself: in the AI Overview, in the ChatGPT recommendation, in the map box. Whoever appears there often wins the customer without a single website "visit" – yet the website remains the source those answers are built from. It becomes less shop window, more foundation.

2. The questions migrate first. AI Overviews appear disproportionately for fully phrased questions ("What does … cost?", "How does … work?", "Who's recommendable for …?"). Those are precisely the questions people ask shortly before a decision. Content that answers such questions precisely and verifiably is the new ticket in – and interchangeable "welcome to our homepage" pages have never been as worthless as now.

3. The gap is the opportunity. 45% of consumers ask the AI; barely 1% of businesses are present in the answers. That gap will close – the only question is with whom. In most trades and towns, the spot in the AI answer is currently simply unclaimed. This is the rare phase when a lead is cheap to build; it ends as soon as the first competitors catch up systematically.

And what about "SEO is dead"?

The numbers don't support it. Google remains by far the biggest way people find providers; AI-referred traffic, at around 1%, is still small. What is true: the rules are changing faster than ever – away from "ten blue links", toward answers assembled from a few sources judged trustworthy. Classic search engine optimisation and AI visibility (GEO) are not opposites but two delivery channels for the same foundations: clean data, genuine reviews, content with substance. How to check both for your business is shown by the ChatGPT self-test and our Google Business Profile guide.

From all these numbers, exactly one consequence follows for a business: visibility is not a state you establish once. The systems that recommendations are built from change monthly – an unmaintained website from 2023 can't answer to that. Which is precisely why we work as an ongoing service instead of a project model.

Frequently asked questions

Is ChatGPT replacing Google? In the short term, no – measured by traffic, Google remains dominant. But search is splitting: factual questions and recommendations are visibly migrating to AI assistants and AI Overviews, while the classic click on websites gets rarer. Whoever is optimised only for the old model loses ground quietly.

Is SEO still worth it for small businesses? Yes – especially locally. Map ranking, reviews, and your own website feed both classic search and AI answers. The work is the same as ever; it just gets delivered in more places, and it rewards continuity more than ever.

What is GEO? Generative Engine Optimization – optimising to be named and cited in the answers of generative AI systems (ChatGPT, Gemini, Perplexity, AI Overviews). The counterpart to SEO, with the same roots: structured, verifiable, consistent information about your business.
