We are all trying to make a few bucks placing ads on our sites.But as you have noticed it's not so easy.Everybody now knows what's going on with those ads and less and less people are clicking them.They just don't look natural inside the websites.But what if you could have ads inside your text?That's right.That's what is Kontera about.Their Contentlinks have become very popular.ContentLinks are contextually relevant keywords discovered in real time on a publisher’s web page that are automatically turned into a link to the most relevant and highest paying text ad from one of Kontera’s thousands of advertisers.So,you can monetize your content in real-time, enabling an incremental increase in ad revenue by providing a new source of untapped ad inventory that does not compete with the other ad programs running on the site. ContentLink also creates a valuable user experience by serving relevant and informational ads that match the user’s interest and frame of mind.I tried them at another blog and I have to say it's great and very easy to place the code!
