Are there any chances, that my created social-network-type site could gain traffic like 5000uv/day WITHOUT spending any money? This site does not exsists yet, but let's pretend that it has good seo, multilanguage, many features and so on.Basic question is, would i make money from this kind of site without spending a dollar?
Yes it possible. But you need to do a lot of work then. You can go to facebook/myspace to promote your site. And don't forget to leave comment at the related niche blog coz it one of the easy way to get traffic.
