I am just signed up an publisher account in LinkXL and starting to sell the context text link ads. Surprisingly, 2 links have been purchased after I install their wordpress Plugin. Their plugin will auto crawl our blog and add the link in post if any advertiser purchase link in the post. I do not need to do anything at all!
They charge 40% on the selling price you set. Well, since i do not have to do anything and the link is auto added into the old page, so it still very profitable to sell link like that. I am waiting the month end and get pay now! So good to find another new source to earn more online money.
