About 1% of website traffic comes from AI referrals, according to benchmark data. About 68% of Google searches end without a click.
The 1% is the figure people quote when they say AI search can wait. It only counts visits. A buyer who asks ChatGPT to compare three vendors, gets a shortlist, then types one vendor's name into Google shows up in your reports as a branded search. The conversation that put that vendor on the list never appears.
The clicks are going missing on the Google side. With an AI Overview on the page, click-through to the top organic result falls 58 to 79%, depending on the study, and AI Mode sessions run around 93% zero-click. Google still pays in clicks, just fewer of them.
The two sides also read the web differently. ChatGPT retrieves through its own index plus Bing. Claude goes through Brave, where 79% of its cited URLs sit in Brave's top 10. Perplexity runs its own freshness-weighted index. ChatGPT, Perplexity and Claude fetch pages without running JavaScript, so a pricing table that loads after the page can rank on Google and still be missing for those three.
Measurement is thinner than most people expect. Google's Search Central blog announced generative AI performance reports in Search Console on June 3, 2026. The fields it lists are impressions, pages, countries, devices and dates, with no clicks and no queries. Bing's AI Performance report, in public preview since February 10, 2026, counts total citations. Neither says what ChatGPT, Perplexity, Claude, Gemini or Grok say about a brand, so that scoreboard has to be built: a fixed set of buyer questions, run per engine every week, because roughly 45% of citations swap on each regeneration in the benchmark data.
RankControl tested what AI answers cite in September: 24 buying questions through OpenAI's API with search on and Perplexity's API, 308 cited pages tagged by type. For the software questions, 118 of 167 cited pages were roundups, and 85 of those 118 were written by a vendor in the same category. Google's guide to AI features says the SEO best practices still apply to AI Overviews and AI Mode, with no additional requirements.
Ram writes about this for RankControl, an AI SEO and AEO platform. RankControl's AI visibility tracker tracks citations across 7 AI engines: ChatGPT, Perplexity, Claude, Gemini, Grok, Google AI Mode and Google AI Overviews. RankControl's AI search vs Google search guide for B2B marketers covers the same comparison in full, and the full write-up on Medium walks one made-up buyer through both journeys.
