RealContext uses Artificial intelligence to retrieve the most relevant ads for your page. And there's an extra feature which makes RealContext unique as well. Keywords are selected based upon which previous selections payed off and which didn't. That means there's a constant feedback process that ensures you gain better revenue from your ads. It also supports blocking certain adds and child-safe filtering and many more options.
AdHearus is a very feature-packed contextual ad provider. As with AdSense, advertisements are targeted but it doesn't stop here at all. The ads are very flexible, you can select from text-ads, banners, rectangles, pop-ups, pop-unders or skyscrapers. You can also display your own ads, through rotation, both on your site and on other affiliate sites, which makes AdHearus a hybrid with conventional advertising technologies. There's a very comprehensive on-line real time reporting feature and, as usual with such services, starting out is free and it's a breeze.
AffiliateSensor has highly customizable ad blocks, which you can make for yourself with an easy to use on-line interface. You also get realtime reporting with clicks-by-domain, page and refferer. There's integration with Google AdSense as well, through the google_alternate_ad_url so AffiliateSensor can be used as a substitute for Google PSA's (Public Service Ads).
