Maximum acceleration of indexing of all trust profiles

Answer 1

No, registration in catalogs has not been working for 5 years already ...

Answer 2

Dmitry says everything correctly, registration in catalogs has not been working for a long time.
Kwork has medium-quality links from posts on forums that you can order.

Answer 3

Alas, this is already dead, only manual registration in thematic closed directories will work

Answer 4

Registration in directories will not add weight to your site
Yandex can impose sanctions for such low-quality links, Google will either simply ignore them or consider them spam and exclude the entire site from the search altogether
