Hi @fullypcgames2, If it is gaming site then get some write ups about your site and distribute it to some news/press sites.
If it is a blog which offers readers some games to download so you can submit your blog to some social bookmarking sites. People are always in search for games and they would find your blog there.
Submit your site to RSS feed submitter. Another thing which you can do is go find some sites similar to that of yours. Exchange some links with them. This will mutually help you both. [Make sure you don't over do this].
I hope this helps.
