Websites AI cites in 37 industries

Every question in the dataset is linked to a tracked business, and each business is placed in exactly one industry according to what it sells. A dental clinic goes to Healthcare, a booking software to Software, a roofing company to Construction. The classification is reviewed every month, as new businesses join the tracking.

The questions mirror what a potential customer might ask an AI about that market: "best roofer near Lyon", "which CRM for a small team", "is this food supplement safe". An industry page therefore answers a concrete question: when an AI talks about businesses like mine, which sources does it rely on?

Each sector has its own trusted references. Regulated fields such as healthcare, finance, insurance or legal services tend to lean on official and institutional sites. Local services (home services, restaurants, construction) usually bring review platforms and directories into the answers. Retail, fashion and electronics questions pull in marketplaces and product pages, while software questions favour comparison sites, documentation and communities.

That is how a platform with a modest overall average can weigh heavily in one sector. For GEO (Generative Engine Optimization, the effort to appear in AI answers), the lesson is simple: the sources worth working on depend on your industry, not on a universal ranking.

The number under each industry is the volume of answers analysed. Smaller industries rest on fewer answers, so their monthly values swing more; give more weight to the average and to long trends.

On each page, look at three things: the domains cited most, the balance between large platforms and specialised sites, and whether competitors' websites appear. Then compare with a neighbouring industry whose boundaries are close, such as Wellness and Healthcare or Construction and Home Services.
