Make guestposts, than make web 2.0 links on that guestposts and than forum profiles, blog commenting, article directories, rss feeds on that web 2.0 links. That's the strongest technic ATM. Don't use too much anchor text, use phrases like "click here", "for more information click here" etc, dont do more that 5-10 links day, don't use 1000 links blasts because they are useless, you can only get google sand. First results you will see few days after guestposts, and after 2 months this tier ranking you will see great results.
