I have been wondering this a bit recently if I am missing out on something. I have been creating hundreds of high quality hand made web 2.0's pointing at my money sites for tier 1. Yes I build high quality tier 2 and cheap gsa blasts for tier 3. However, I have been wondering if it is a good idea to do internal linking in my web 2.0s? Is that going to make much of a difference? I could go back to each of my web 2.0's and add some internal links to see if it does anything but it would take me quite a while.
