And the full check-up
Each tool above answers one question. The full check-up answers the one that comes before them: what is actually wrong with this site? Speed on mobile, indexing settings, whether a visitor can contact you, the platform you run on — one health score, and the fixes in the order that pays. Free too, and the whole report is on screen: there is no email to hand over.
One more tool exists on the French side and has not crossed over: a cold-call scam detector, built around the scripts French cold-callers actually use. It needs rewriting for another market, not translating.
