Ahrefs

Type: organization / product | Domain relevance: Independent SEO/AEO data source; first non-Caleb quantitative GEO method in the wiki.

Summary

Ahrefs is an SEO software company whose public education (YouTube course by Sam Oh, AI SEO Course for Beginners: Complete AEO Tutorial (Ahrefs)) is the wiki’s first data-backed, independent GEO / AEO (Getting Recommended by AI) playbook. Their first-party numbers — AI search as 0.5% of traffic but 12.1% of sign-ups; branded-mention correlation 0.664 with AI Overview visibility across 75k brands — are the empirical counterweight to Caleb Ulku’s 250-document training story. Tool placement (Brand Radar, Site Explorer) is a standing commercial flag; keep the measurements, discount the product steps.
