Google AI Overviews cut top organic clicks by 58%; $950 audit measures brand share inside AI answers

Physicist Bruno Gonçalves launched an AI visibility audit course/service arguing the buying decision now happens inside AI answers: per an Ahrefs study of 300,000 keywords, Google AI Overviews cut top-organic-result clicks by 58%; AI chatbots drove just 0.25% of global referrals in August; SparkToro found ChatGPT and Google AI repeat the same brand list less than 1 in 100 times, so single spot checks are meaningless.

Method: build a 20-50 question set from sales calls and support tickets; run each question 10-20x per engine (ChatGPT, Claude, Gemini, Perplexity) via official APIs with web search on; score answer share and citation share with 95% confidence intervals against three competitors; check what non-JavaScript-running AI crawlers see vs humans; deliver a ranked fix list, ship fixes, rerun. Snapshot pricing: $950.
