When a potential customer asks ChatGPT "what's the best plumber in Denver," something happens that most business owners don't realize: the AI doesn't search the web in the way Google does. It draws on training data cross-referenced against live sources to generate a single confident recommendation. Your business either appears in that answer — or it doesn't.
AI visibility is a measure of how well AI platforms know your business, how accurately they represent it, and how confidently they recommend it. It has nothing to do with your website's search ranking. A business with a decade of SEO investment and a page-one Google ranking can have a 0/100 AI visibility score — invisible to the platforms that an increasing share of your customers use to find services like yours.
The shift is structural. Google ranked signals about your website. AI platforms evaluate signals about your business — its data quality, verification status, and structured completeness. Different rules, different winners.
