Yandex Catalog stores information on tens of thousands of Russian websites. The sites are pigeonholed by topics, information type and regions. The category tree of the catalog is very simple: there are only eight major topics, each of them not more than four levels deep.
Besides websites, the categories of the new version of the catalog feature news and products related to a particular topic
Yandex Catalog was compiled and is updated manually. Its editors are impartial in sorting out websites, writing their descriptions and checking out whether the information is up-to-date.
