Geology and Ahrefs Brand Radar both surface AI brand mentions, but they are different kinds of offers. Geology is an AI-driven SEO and GEO agency: AI agents run strategy and execution, and the team ships the work (technical SEO, content, schema, internal linking, off-site citations) while tracking visibility weekly across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews. Brand Radar is an add-on inside Ahrefs, attached to the SEO suite teams already use for backlinks, keywords, and rank tracking.
If you want a partner that watches AI answers and ships the fixes, Geology does both. If you have a senior in-house team that wants AI mention data inside the Ahrefs workflow it already runs, Brand Radar is the path of least friction for that team.

What Ahrefs Brand Radar does
Ahrefs Brand Radar sits inside the broader Ahrefs platform and tracks brand mentions across the web, including AI Overviews and answer engines. It uses Ahrefs' crawl and index to log where a brand shows up, who is mentioning it, and how visibility changes over time. The natural buyer is a team already running Ahrefs for keyword research, backlink analysis, and content audits. Brand Radar adds a new layer to that workflow without making the customer adopt a second tool. The trade-off is scope: it is a mention tracker inside an SEO suite, so the work around prompts, content, and structured data fixes stays with your own team.
What Geology does differently
Geology is an agency, so the output is shipped work, not another report to act on. Page audits flag the URLs an AI is misreading and explain why. Prompt research captures the actual queries buyers run, not just keywords with monthly volume. The team turns gaps into content and publishes it, and AI agents handle common fixes (schema, FAQ structure, internal linking, metadata), so a finding from Monday becomes a deployed change by Wednesday. Tracking is model-aware: results are reported per AI surface, because how Perplexity ranks you is not how ChatGPT does. For one enterprise client, that approach produced 75% organic growth and 3x AI mentions in six months.
Pricing
Ahrefs Brand Radar is included with Ahrefs subscriptions, with the exact features and quotas tied to your plan. Pricing is tiered and public, so you can size it without a sales call. Geology starts at $3,000 a month, and that covers the SEO and GEO work itself, not only the data. For teams already paying for Ahrefs, Brand Radar adds no marginal cost; for teams that want results shipped rather than tracked, Geology is sized for that scope.
When Ahrefs Brand Radar wins
If you have a senior in-house SEO team that works inside the Ahrefs UI every day and only wants a data feed to run the work yourselves, Brand Radar is the lowest-friction way to add AI mention tracking. You get the data with no new login, contract, or training cycle.
When Geology wins
If you want SEO and GEO results rather than another data tab, Geology wins. You get measurement across all major AI surfaces plus a team and AI agents that ship the technical SEO, content, schema, internal linking, and off-site citation work that moves those numbers.
