Can anyone tell me all methods of link building for blogs ? I used to write three post per week. So any idea ?
Ohh, you mean inner page links. The best way is to write good content, so it gets shared on social networking sites and other blogs, etc. You can also take a more proactive approach and get links to blog posts, which is no different to getting links for the homepage.
I would advise against link building for each inner page unless the title is optimized for a term that could get some traffic. If the post title is something random, or an extremely hard phrase you are better of taking those link building efforts to your main efforts (homepage, main pages, etc) and let the authority flow naturally to those inner pages, but if it is a well-written inner page submit it to social bookmarking sites, rss feeds, maybe forums, etc.
