What Percentage of Searches Now Show AI Answers?
48% of Google queries trigger AI Overviews. ChatGPT processes 2.5 billion prompts daily. Gartner predicts 25% drop in traditional search.
48% of Google queries now trigger AI Overviews. These are AI-generated summaries above traditional results. For informational queries the figure is 70-80%. ChatGPT processes 2.5 billion prompts daily, with roughly 65% being search-intent queries. Gartner predicts traditional search volume will drop 25% by the end of 2026. The shift is measurable and accelerating.
Google AI Overviews: the 48% figure
Google's AI Overviews now appear on roughly 48% of all search queries. That average masks a split by query type:
| Query type | AI Overview rate | Example |
|---|---|---|
| Informational | 70-80% | "What is AI search optimisation" |
| Commercial investigation | 30-40% | "Best AI SEO agencies UK" |
| Navigational | 10-15% | "Rank4AI login" |
| Transactional | 5-10% | "Buy SEO audit" |
If your business targets informational queries like guides and how-tos, most of your search results pages already include AI-generated content. Your organic listing is no longer competing only with other websites. It competes with Google's own answer.
ChatGPT as a search engine
ChatGPT processes roughly 2.5 billion prompts per day. An estimated 65% carry search intent. That is roughly 1.6 billion daily queries that function as search. By volume, ChatGPT is one of the largest search engines in the world.
Users type into ChatGPT what they used to type into Google. The distinction between "chatbot" and "search engine" no longer matters for marketing. If someone asks ChatGPT "best AI search agencies in the UK" and your business is not mentioned, you have lost a potential customer.
The Gartner prediction: 25% drop by 2026
Gartner's forecast predicts a 25% decline in traditional search volume by the end of 2026. People are not searching less. They are searching differently. AI assistants, conversational interfaces, and platforms that give direct answers are replacing lists of links.
The implications for businesses:
- Organic traffic from Google will decline - even if rankings hold, fewer users will click through
- AI citations become the new traffic source - being mentioned by ChatGPT or Perplexity equals ranking on page one
- Multi-platform visibility is essential - Google alone misses the growing share of queries other AI platforms handle
Other AI platforms by volume
| Platform | Estimated daily queries | Primary index |
|---|---|---|
| Google AI Overviews | 4+ billion (48% of ~8.5bn daily) | |
| ChatGPT | ~1.6 billion (search-intent) | Bing |
| Copilot | Not disclosed | Bing |
| Gemini | Not disclosed | |
| Perplexity | ~15 million | Multiple |
| Claude | Not disclosed | Own crawl + web search |
What this means for your business
AI in search is not a future trend. It is a current reality affecting roughly half of all search activity. Businesses that only optimise for organic rankings already miss a growing share of how customers find information.
AI search is not a separate channel. It is the evolution of the channel you depend on. The same queries your customers type into Google are answered by AI before they see your organic listing.
