We monitor how companies/brands rank in LLMs/AI Search, we don't use the API but the user interfaces (since these are totally different). We run thousands of prompts to analyse responses and combine that with website traffic to get an understanding of what is being said and how well you rank.

I didn't anticipate Google moving to AI mode so fast, to be totally honest, which makes it really interesting because we likely see rank tracking and keyword tracking disappear in the near future.

As a fun side project, I run https://homestra.com a kind of Zillow for Europe but for second/vacation homes
