I think the first decision with Ahrefs Brand Radar is quite simple: do you want to explore a category, or do you want to keep checking the questions you already care about? Ahrefs sells both, but you don't have to buy both.

For an SEO team trying to understand which competitors get into AI answers and which pages get cited, the research index is useful. For a team that already has its buying questions, I would look at custom tracking first. It can cost less than a dedicated tracker for the same panel, so I wouldn't rule it out on price.

If you're an agency, you also need to think about what your client receives. White-label reports help with that part. But first you need an answer that matters to the client, and a clear reason for the work you recommend.

Ahrefs' research index gives you existing answers to explore before you write a monitoring list. It contains more than 400 million search-backed prompts, and there is no cap on the brands or domains you can analyze.

The useful metric depends on what you want to explain. A brand mention tells you that the answer names the company. A citation identifies a source used in the answer. Those can lead to different work: your brand might appear while the answer cites an external page, or your website might be cited without the answer recommending your product.

For a content decision, I would go into the cited pages rather than stop at the domain count. A domain can cover many subjects; the individual page tells you whether the evidence is relevant to the buying concern. For a brand-presence question, begin with mentions and read how the answer describes the brand. Being named is not automatically being recommended.

Say you're researching CRM software for a small sales team. This is a hypothetical investigation, not a customer result. Comparing every answer about CRM would mix too many situations. A company looking for a simple sales pipeline has a different problem from one replacing a large enterprise system.
