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.
UK mortgage answers revolve around fixed terms and your LTV band, benchmarked against the current market and Bank of England backdrop.
LTV band gates the rate
Answers tie the achievable rate to your loan-to-value and deposit size. The advertised rate is presented as conditional on LTV, so lenders that show rates by LTV align with the AI's framing.
Fixed-term choice is the main decision
The models focus on two and five-year fixes and how long to lock in. Buyers are guided on term length, which rewards lenders that explain the trade-off clearly.
Rates are benchmarked to the market
Answers reference the current market and Bank of England rate as context. Buyers are taught to judge offers relative to the backdrop, favouring lenders positioned clearly against it.
