Let's build a list of link building techniques.
No 'good tip' and 'thank you' posts please :P / Unless you have a valid point to add.
Let's just post solid link building tips.
- Forum Signatures - You put a link in your signature on any forum (preferably of your niche) & every post you make on the forum gives you at least a single one way link back. Another thing you can do is buy forum signatures of other members on forums.
- Wordpress themes - Either you can design a WordPress theme or get someone to design one and put your link in the footer. The more popular and the more the theme is used the more backlinks you get. (This applies to any kind of themes and is not just related to WP)
