Claims backed by evidence

Whether the page's factual claims carry the numbers, named sources, or citations a reader - or an AI assistant - would need to trust them.

This is one of the strongest measured levers in AI visibility research: content with statistics, quotations, and cited sources is substantially more likely to be quoted in AI answers, because a claim with a number and a source is defensible for the AI to repeat, while an unsupported assertion is a liability.

When this is flagged

The report flags this when claims that would reasonably need support - figures, superiority claims, safety or efficacy statements - are presented bare, with nothing a reader could verify.

How to fix it

Attach evidence where a skeptical reader would want it: the actual number, the named source, a link to the study or documentation. One well-sourced claim outweighs several unsupported ones.
