Enter a URL and this checks, for real, whether Google Analytics 4, the Meta Pixel and Google Tag Manager are installed on that page. That is the first question any paid media plan depends on: if you cannot measure it, you cannot optimise it.
This free check is deterministic, it reads the page and looks for real tag signatures. No number here is generated by a model, and nothing is invented for a tag that is not found. It does not tell you whether there is demand worth chasing, that needs a real audit with keyword and market data, which is a separate, paid engagement.
