Do Backlinks Still Matter for AI Search?

Backlinks still matter for AI search, arguably more than some marketers expected. Language models weigh whether a site is mentioned and linked elsewhere on the web as one signal of real world trust, similar to how Google has used links for decades.

The difference is that AI systems also weigh unlinked mentions, a brand name showing up in a forum thread or news article without a hyperlink still counts as a trust signal, which is new compared to classic SEO.

That means a site's reputation across the whole web, not just its link profile, now feeds into whether it gets cited.

Earning that wider reputation is part of the long game LLM SEO software is built to support.
