How to properly promote a social site with user-generated content for the first time?

Question

contextual advertising

I have a successfully running site with completely user-generated content. People are actively sitting, creating content, clicking on ads and generating income.
When I launched this site, I was lucky and the first part of the audience came by themselves and there were no further difficulties.
Now I'm running a copy of this site in another language, and the difficulty appears - there is no content to start. People from advertising come, see an almost empty site and leave. The problem is that I can’t create or order content on my own, the service is social to some extent and “posts” of users without further interaction between them do not make any sense.
How to get the first part of the audience that can be "self-sufficient" in terms of creating and consuming content? Is it even possible to do this using only contextual advertising?

Answer 1

This is what you need in the Far Far Away Kingdom, so that "two from the casket" do everything for you.

Buy on some specialized forum on the topic of the site.

Answer 3

"The problem is that I can't create or order content on my own" - what do you mean I can't? Either you are in business, and business requires investment, or you suck your paw.
Users do not need empty sites, so you need to work.

Oh, somehow everything is vaguely written) what is the point of the project in Russian, what is it about, how was the first traffic attracted?
otherwise it all sounds strange, as if you are the creator of giktimes or a site on the darknet selling drugs)
