For me, the best way to build links is to make Guest Posts.
Also if you build good relationships with other bloggers, you will get backlinks as a side effect.
A special note goes to this:
Some blogs reward their readers for comments and links.
This means that their comments and trackbacks gives you dofollow links.
This doesn’t mean to spam these blogs.
This want to be an input to actively partecipate to these blog community if you find their contents valuable.
