AI Search Visibility is a measurement concept that quantifies how often a brand, product, executive, or topic is mentioned inside the answers generated by AI search engines — ChatGPT, Perplexity, Google AI Overviews, Claude, GLM, and Copilot among others. It is usually expressed as a citation share: of the top 50 commercial queries in a category, what percentage of generated answers name your brand versus a competitor. Unlike classic SEO rank tracking, which lists a position 1 through 10 on a single SERP, AI Search Visibility is multi-engine, multi-query, and qualitative — being mentioned positively, negatively, or neutrally matters as much as being mentioned at all. Harch Atelier tracks AI Search Visibility weekly across four engines and reports it on a 0 to 100 visibility score. The score is broken down by engine, by query cluster, and by sentiment. The benchmark matters because prospects increasingly skip the blue-link SERP entirely: if ChatGPT recommends three competitors and never mentions you, you are losing deals you never see. A visibility score below 20 means the brand is functionally invisible in the fastest-growing discovery channel of the decade. A score above 60 means the brand is a category-defining answer that engines reach for unprompted.
