Broad brand mentions across the web (incl. YouTube)
Branded web mentions and YouTube mentions are the strongest measured correlates of brand visibility in Ahrefs' 75k-brand studies, but among top domains the link is strong for AI Overviews and weak for ChatGPT and Perplexity.
Real evidence that depends on platform/context, or sources conflict.
Downgraded to Mixed (Oct 2026 audit): all data is from one vendor (Ahrefs), correlational, and platform-dependent (0.65 AI Overviews vs 0.15 ChatGPT among top-50 domains).
Guidance only
- Off-site; needs a mentions index. The free check may show 'brand name consistency' only.
Caveats
- — Correlational studies dominate this field. AI citations churn: a small 15-prompt preprint (arXiv 2609.22655; the author sells AI-visibility tooling) saw each engine's cited URL set change by about 67% on average from one day to the next, with under 1% URL overlap across engines. Toronto (2610.15033) found only about 40% of the within-site pattern of ChatGPT citations still held two weeks later, and 14% after ten weeks. Re-verify yearly.
- — Off-site / not measurable from a single page fetch. Guidance only: not graded in the free check.
