Need help promoting new WP site.

Now I’ve got my WP site up and running.

I’ve signed onto several search engines, done some meta on the home page, etc.

Is there a document or something:

That helps in all the steps to promote your site,i.e, addons and stuff you need to acquire?

Things you need do with the site?

Is there some docs on how to do SEO?

Thanks for any tips, links or suggestions.
