How can you determine the theme of the site?

Question

Search Engine Optimization

Hello everyone
There are over 1000 sites that need to be sorted by topic. Previously, I remember Yandex put down a theme for each site and it could be parsed through the analytics service. But now I can't find anything similar.
Is there any way?
