Do backlinks still count as a ranking factor for AI search?

Yes, as one of several authority signals, though they're weighted alongside content clarity and structure.

Is there one factor that matters most?

Crawlability is the prerequisite for everything else — content that can't be accessed can't be cited regardless of quality.

How do I audit these factors on my own site?

Start with robots.txt and schema validation, then manually test target queries across ChatGPT, Perplexity and Google AI Mode.
