I did two different blasts of forum profile links to my 1st tier links. The first blast was for the top 10 article directories and the second blast was for the web 2.0 properties and for the youtube video.
This might be considered a white hat technique, but since I build a links directly to my niche site.
It’s an easy and quick way to get a tons of links to my 1st tier.
What this does is it creates hundreds of accounts in different forums and adds your desired URL as the accounts homepage. It randomly chose between all of the 1st tier links.
