Here is a way to get tons of quickie backlinks to your website/blog posts. Two sites; Xomba (PR4) and Mashable (PR7) have places where you can literally just enter 1 or two sentences and then 1 or more links to your site. On Xomba, you create what is called at Xomblurb. It is a minimum 50 word mini post then you can enter 2 links to your webpages. If you have articles, up somewhere you can take the first sentence and enter it as a xomblurb and have one link to the full article and another to your site. The good thing about xomba is that you can also get adsense revenue with your mini-posts/links. They do a 50-50 split of adsense revenue with you so essentially its a paid high PR backlink. On Mashable you can enter tips anonymously with 100 word minimum and then a link to your site. Mashable isn't huge but they claim to have about 2.4 million users. Again the same strategy with existing articles can be used. These go very fast. You can literally create dozens of these miniposts with links in just 15 minutes.
