Ask ChatGPT one question a buyer would ask (for example "What is the best invoicing tool for freelancers?") and see whether a brand is named in the answer, in which position among the options it lists, what it says about it, whether it cites the brand's site, and which sites it cites. The question runs once in ChatGPT's web app (logged out, through a collection service) and takes a few minutes: the first call starts it, then call again with the same domain and question to get the answer (no extra cost). One free new question a day per user; an answer someone already got today is shared. Use this for "does ChatGPT recommend us?" or "why does ChatGPT pick our competitor?".
