For twenty years, search marketing meant ranking on a page of links. Now many searches end with an AI-written answer — on Google, in ChatGPT, Gemini, Perplexity or Copilot — and the user may never click.
What the evidence shows
- Pew Research Center tracked the Google searches of 900 US adults in March 2025. When an AI summary appeared, users clicked a traditional result in 8% of visits, versus 15% when there was no AI summary. About 18% of searches produced an AI summary.
- Ahrefs compared 300,000 keywords and found that an AI Overview was associated with a 34.5% lower average click-through rate for the top-ranking page (March 2025 vs March 2024).
- Bain & Company (survey of 1,117 consumers, December 2024) reported that about 80% of search users rely on AI summaries at least 40% of the time, about 60% of searches end without a click to another site, and estimated organic web traffic falls 15% to 25% as a result.
- Gartner predicted in February 2024 that traditional search engine volume would drop 25% by 2026 as people turn to AI chatbots and virtual agents — a prediction, not a measurement.
What it means
- Fewer clicks for the same rankings. Traffic-based SEO targets will look worse even when you "win".
- The answer is the new shelf. If an AI assistant describes your category without you — or describes you wrongly — you lose consideration before any click.
- Different sources matter. AI answers draw on pages, reviews, forums, comparison sites and news. Your own site is only part of it.
What stays the same
Clear, expert, trustworthy content still wins. Gartner's own advice was to focus on distinctive, valuable content that shows expertise and trustworthiness, rather than keyword tactics.
First steps
Shift goals from "rank and traffic" to "presence, accuracy and conversion": are we in the answer, is it right, and do the visitors who do click convert?
