My purpose is to find a service (provide by Google or others) able to extract the frequencies of the web-researches of a website or a key term. I know Google Trends but I would need a service that can look at the hierarchies (the terms correlated with my query) and that indicates also the geographical provenience.
not sure if I understand 100% what you need/are asking, but common crawl has data like this:
