I wrote a guest post over at David Harry’s site Huomah
, and I decided to talk about paid links (also called nepotistic links) and present recent research in that area so SEO‘s who do use them can assess whether they are misleading links or not. It is possible to see that an automated solution is fast approaching completion and that this will affect their site’s performance.
I hope you enjoy it, and find it useful. I am available for questions should you have any. I’ll do my best to answer and if I can’t I’ll point you to someone who can.
Enjoy 
an interesting article. however i don’t think all links described can be counted as paid links, and all paid links cannot be considered bad links.
