The damage is silent: a buyer asks ChatGPT "who are the best [your category] in [city]?" and gets 3-4 recommendations that don't include you. They never visit your site. No bounce, no direct exit, no data signal. Just a customer who became someone else's. ChatGPT: 100M+ weekly active users. Perplexity: hundreds of millions of monthly queries. A growing % of professional buyer research starts with AI before Google. Most at risk: research-intensive purchase categories — agencies, consulting, B2B software, professional services, healthcare, legal.
