Selling Links Violates Google Policy
I came across an interesting article in the Google Support directory that discusses Paid Links.
Specifically it says: Buying or selling links that pass PageRank violates Google’s Webmaster Guidelines
Google goes on to say such practices of selling links will negatively impact that site in Google search results.
There are actually many text link brokers out there, and if you are paying for such services there is probably a high percentage Google isn’t counting these links you are paying for.
I personally don’t believe in buying or selling links to boost your PageRank, we need to keep the web open and let people link under normal circumstances on their own accord.
Google goes on to say you can sell links if this for ‘advertising ‘, and in such cases you should add rel=”nofollow” to the link.
