InLinks, and new service from text-link-ads, works similar to Kontera. It takes keywords on your page and makes them links, which you get payed for when clicked. However, it makes them like normal links, so you cannot tell the difference. It is PHP Powered (like a plugin), so users cannot tell real from inLinks. Do you think this is deception, or would you be willing to give this a shot on your blog/website?
