What kind of sites get cited
This is what AI links to as its sources, which is not the same as the brands it names above. AI often recommends a provider by name but sends the citation to a publisher or affiliate instead, so “First-party brand” means a link to the provider’s own website. Here is the mix by engine.

The themes behind the recommendations
Looking past the brand names, these are the concepts and buyer intent the AI answers kept returning to for this product. Each finding starts with what the engines foreground, then what it means for you.
Health insurance answers cannot resolve without your location. The models route almost everything through the ACA marketplace and your specific zip code.
The marketplace is the default path
Healthcare.gov and the ACA marketplace frame most answers rather than direct-to-insurer buying. Buyers are pointed at the exchange first, so plans presented in marketplace terms align with how the AI thinks.
The answer is location-bound
Zip code and local plan availability are raised as prerequisites in nearly every response. The models will not give a clean national ranking, which rewards insurers that emphasise their regional networks.
Quality ratings carry the argument
Plan quality is judged through NCQA ratings and bodies like KFF, not insurer claims. The AI leans on independent quality scores, so accreditation and ratings presence are decisive.
