AI visibility research

The category report and source-map observations below come from VisiScan — an autonomous agent that reads a business site, asks buyer-intent questions across ChatGPT, Claude, Perplexity, and Gemini, and records which businesses are named, which competitors appear instead, and which domains each engine cites. The pages publish aggregated observations with their measurement basis and limitations; they are not permanent rankings or estimates.

Quick answer: what the research shows

VisiScan research shows which businesses AI engines name, which competitors appear instead, and which domains those engines cite. Use the index for rankings, source maps for citation opportunities, and the methodology for how each observation is measured.

AI Visibility Index

Live leaderboards ranking businesses by how often AI engines recommend them. Rebuilt nightly from real scan results. Each score is verifiable — the scan and its evidence are preserved.

Citation source maps

For each industry, we track which domains ChatGPT, Claude, Perplexity, and Gemini actually cite when answering buyer questions. These source maps show where AI engines go for business information — which directories, review sites, publications, and platforms carry the most weight.

The data is updated from persisted scan results. Each industry page states the available count, country, and last-seen evidence; the current directory is domain-level and does not retain an engine-by-engine breakdown.

First-party benchmark: VisiScan's day-one score

We pointed our own AI visibility audit at visiscan.app on the day the product started measuring real scans. The result — 40 live answer observations across 5 buyer questions and 4 AI engines — gives anyone a transparent baseline to compare against. The full methodology and score breakdown are published and reproducible.
