Hello, I try to read as much as I can through the forums but still not sure about few things. Not sure what is link wheeling and is there any difference between social bookmarking and link wheeling? eZine articles - I've read through the forums that ezine isn't a good source for building backlinks anymore? Incase I have a website that already indexed on google and has PR2, do I still need social bookmarking\link wheeling? Thanks.
