Is there a service for determining the subject of the site?

Question

Google Webmaster Tools

Friends, tell me the service for determining the subject of the site, I found 1 on ru.megaindex.com, but it hangs, and then gives an internal error.

Answer 1

There's no such thing. Because there are a lot of questions: what are topics, what to do if they are different on the site, what level of different topics. Screws and hammers are construction or different subjects. What to do if the site has a hundred thousand million pages ...

Answer 2

Yes - Majestic.com - the service assigns a theme to the site according to its link mass. The indicators of this service are key in determining the subject of the site. Sometimes, of course, it doesn’t match, for example - an SEO specialist’s blog can indicate that it is of a medical theme, but this is more likely from the SEO specialist’s curvature :).
