Ahrefs is the SEO platform many teams already trust for backlink data and keyword research, and Brand Radar is its newer view into how often a brand surfaces inside AI answers. Geology is a GEO-native platform that combines cross-platform tracking (ChatGPT, Perplexity, Gemini, Copilot, Google AI Overviews) with execution: page audits, prompt management, content briefs, and an agentic optimization layer. If you want a directional read on AI visibility inside the SEO tool you already pay for, Ahrefs Brand Radar fits that brief. If AI search is a real growth lever, Geology is the system of record that closes the loop from data to action.

What Ahrefs does
Ahrefs is a long-standing SEO platform known for its backlink index, keyword research, rank tracking, site audit, and content explorer. The homepage frames the suite around organic growth and competitive research, and it is one of the most cited SEO tools on G2. Brand Radar is the AI-era addition: it surfaces how frequently a brand or topic appears across major answer engines, including ChatGPT, Perplexity, Gemini, and Google AI Overviews, with a share-of-voice view. Reviewers describe Brand Radar as a useful directional signal that lives alongside the SEO data they already pull, rather than a complete prompt-tracking or execution toolkit.
What Geology does differently
Geology was designed for the workflow a GEO team runs every week, not as a feature inside an SEO suite. Tracking covers all five major surfaces with prompt-level granularity, so you can see the questions buyers actually ask and which answers cite you versus a competitor. The execution layer is what changes the day-to-day. The page audit isolates the pages an AI is misreading and tells you why (missing schema, weak entity coverage, thin FAQ structure). The content workspace converts gaps into briefs your team can ship, and the agentic optimization layer applies common technical fixes automatically. Where Ahrefs gives you a Brand Radar number, Geology gives you the number, the cause, the brief, and the fix in one product.
Pricing
Ahrefs runs tiered subscriptions starting in the low hundreds per month, with credit-based usage on heavier modules and seat-based pricing on enterprise plans. Brand Radar is included on certain tiers but the heavier crawl and report volumes typically push working teams into the higher tiers. Geology is a transparent subscription scoped to AI search, generally lower than upgrading an Ahrefs seat to unlock heavier Brand Radar usage, and the seat economics are simpler.
When Ahrefs wins
If backlinks, rank tracking, and keyword research are still the primary SEO levers for your team, Ahrefs is the right call. The backlink index is hard to match, and Brand Radar gives you a sensible AI-mention pulse without learning a new tool.
When Geology wins
If your AI visibility KPI matters at the board level, Geology wins. You get cross-platform tracking with prompt-level depth, an audit that points at the specific pages holding back AI readability, and an agentic layer that ships the schema and structure changes the data points to. Teams who already use Ahrefs for SEO frequently add Geology rather than chasing GEO inside a tool that was not built for it.
