Who wins the citations

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.

What the answers are really about

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.

Auto loan answers are built around your credit profile and a strong tilt toward credit unions. The rate is presented as something you qualify for, not a fixed headline.

1

Credit unions are the default recommendation

Credit unions, especially member-owned lenders, dominate the answers over banks. The AI treats them as the value option, so credit unions punch above their marketing weight in these results.

2

Your credit score gates the rate

Almost every answer ties the APR to credit tiers, repeatedly citing the excellent-credit rate. Buyers learn the advertised rate is a best case, which favours lenders that publish clear rate-by-credit ranges.

3

New versus used changes the answer

The models distinguish new-car and used-car financing and the rates attached to each. Content that separates the two scenarios maps onto how the AI already splits the decision.
