An Honest Read
Where Each Is Stronger
Where Ahrefs Brand Radar is stronger
Ahrefs' own pages describe a no-setup AI Visibility Index built from real search queries, daily tracking of prompts you define, YouTube, Reddit and TikTok visibility, and Custom Prompts packages from $50/mo, all inside a full SEO suite. Modern Discovery does not offer a search-demand index, an SEO suite or social-channel tracking.
Where Modern Discovery is stronger
Modern Discovery measures Recommendation Rate, the number one pick, with Recommendation Inclusion Rate, on a public, versioned methodology. On Pro and Enterprise it shows where AI knows your brand but picks a competitor, and how Recommendation Rate moved after an action. A top-position recommendation metric, a mention-to-recommendation gap measure and a before and after re-measurement loop were not identified in publicly available documentation reviewed on 2026-10-03.
Recommendation Rate measures AI answer outcomes, not revenue. Re-measurement shows whether the rate changed after an action. It does not by itself show that the action caused the change or produced incremental sales.
Choosing Between Them
Choose Ahrefs Brand Radar if
- You already use Ahrefs for SEO and want AI visibility in the same account
- You want daily tracking of prompts you define, at a low entry price
- You want YouTube and Reddit visibility next to AI answers
Choose Modern Discovery if
- You need to tell being mentioned from being the number one pick when buyers ask AI which brand to choose
- You want a public, versioned methodology across a fixed set of six surfaces
- You want to see where AI knows your brand but picks a competitor, then re-measure after a fix
