Ahrefs AI Search Visibility and ChatGPT Brand Mentions
Ahrefs Brand Radar is an Overview-heavy research index at $199 plus an Ahrefs plan. Promptwatch is the ChatGPT mention ledger we run next to it.
Ahrefs AI search visibility is Brand Radar. Buyers type "Ahrefs AI search visibility ChatGPT brand mentions" because they already live in Ahrefs and want the chatbot column too. Brand Radar is good at category-level Overview and assistant research. It is a weak ChatGPT mention ledger. We keep Ahrefs for links and content gaps. We run Promptwatch for the prompts you actually care about.
Brand Radar starts at $199/mo per AI index on top of an Ahrefs plan (from $129/mo). Promptwatch Explore is free (ChatGPT, 10 prompts). Essential is $95/mo. Paid plans watch ChatGPT, Gemini, Claude, Perplexity, and Google AI Overviews daily from the real UI. Site: promptwatch.com.
What Brand Radar is built to do
Brand Radar sits on Ahrefs' crawl index. It measures brand mentions and citations across ChatGPT, Perplexity, Gemini, Copilot, and Google's AI Overviews and AI Mode, using a corpus of 260 to 405 million prompts modeled from keyword and People Also Ask data. For "is our AI presence growing" and "who dominates citations in this market," that scale is the point.
The pivot is the real Ahrefs advantage. A cited page that beats you is one click from its backlink profile and content gaps. No standalone GEO tracker follows that thread inside the same login.
If your Monday question is market share at index scale, one Brand Radar index can earn the $199. If your Monday question is "did ChatGPT name us on these 40 sales prompts yesterday," you are asking for a different product.
Why ChatGPT mentions are a different job
ChatGPT has 820M+ weekly active users. People do not talk to it the way they type Google keywords. Brand Radar's prompts are modeled from Google search data, not observed conversational queries. "Estimated Impressions" weights by Google search volume. That is a research model. It is not a list you typed.
An independent January 2026 test found Brand Radar reporting 3 ChatGPT brand mentions for a site where manual checking verified 123, an undercount of about 97%. Chatbot indexes refresh on roughly monthly snapshot cycles, so week-to-week movement is mostly invisible.
Treat any absolute ChatGPT count from Brand Radar as a floor, not a fact. Use it for direction. Do not put it in a QBR as the mention number.
Promptwatch takes the other path. You define the prompts. Paid engines are checked through the real UI. Citation analytics sit behind each hit (page and domain, plus Reddit and YouTube when those sources appear). That is a ledger, not a modeled index.
What the $199 index actually buys
Brand Radar's free beta ended. You need:
- An Ahrefs base plan, from $129/mo
- $199/mo per AI index, or $699/mo for the all-six bundle
- $50/mo per 2,500 custom prompt checks if you want your own prompts tracked
A full configuration lands between $828 and $1,148+/mo. There is no white-label or per-client structure, so stacking this per client gets expensive fast. Native indexes do not include Claude, Grok, or Meta AI.
Semrush AI Toolkit is the other suite add-on people compare here: $99/mo per domain, 25 prompts, one user. Cheaper for a single domain you already track in Semrush. Same class of problem: modeled prompts, not a list you fully own.
| Job | Instrument |
|---|---|
| Category share at index scale | Ahrefs Brand Radar |
| Backlink pivot off a cited URL | Ahrefs (the base plan) |
| ChatGPT mention on a prompt you wrote | Promptwatch |
| Overview impressions on Google | GSC generative reports |
Promptwatch as the mention ledger
Promptwatch Essential at $95/mo is the ChatGPT mention log we put next to Ahrefs. Explore is enough to prove the gap: run ten buyer prompts, then compare the dashboard to a Brand Radar ChatGPT count. Professional is $245/mo for 150 prompts. Business is $579/mo. Agency Kick-off is $199/mo if you need unlimited projects and 10 seats.
Essential includes visitor analytics through a script or GTM, but it has no listed crawler-log allowance. Professional at $245/mo adds 25M crawler logs that show whether GPTBot or related bots fetched the URL. Business and the self-serve agency plans also include crawler allowances. Those views sit next to the mention series. Brand Radar does not replace them.
Keep Brand Radar if you already pay for Ahrefs and want quarterly competitive research. Do not fire Ahrefs. Do not treat Brand Radar as the only ChatGPT number. Method: how we rank. The rest of the tools list is there if you want the longer pages.
FAQ
Is Brand Radar included in a regular Ahrefs subscription?
No. The free beta ended. You need a base plan (from $129/mo) plus $199/mo per AI index or $699/mo for all six.
How bad is the ChatGPT undercount?
Bad enough to change how you use the number. The January 2026 test was 3 reported mentions versus 123 verified. Use Brand Radar for trend direction, not a precise ChatGPT count.
Does Brand Radar track Claude?
Not in the native indexes. Promptwatch paid plans include Claude alongside ChatGPT, Gemini, Perplexity, and Overviews.
Should I cancel Ahrefs and move to Promptwatch?
No. Keep Ahrefs for links, content gaps, and Overview-adjacent research. Add Promptwatch for the prompt-level ChatGPT ledger. They answer different questions.
What to do this week
- Write 15 ChatGPT prompts you already hear from buyers. Include one competitor name.
- Run them by hand. Count mention vs citation.
- If you already have Brand Radar, pull the ChatGPT mention count for the same brand and treat it as directional only.
- Open Promptwatch Explore (free, ChatGPT, 10 prompts) or Essential at $95/mo.
- Keep the Ahrefs index for category research. Report "index share" and "prompt mentions" as two lines.
