Ad Pepper provide a wide number of ad types to publishers, raning from the standard 468×60 banners and 120×600 skyscrapers to the larger ad sizes of leaderboards and pop-unders. They have good rates for traffic from their main bases of Europe and USA, averaging about $0.80+ eCPM for leaderboards, making them comparable to Valueclick and Burst, although the ads for the international campaigns is somewhat lower, around the $0.05 to $0.10 range. However, you are able to set up a default for the low paying international traffic and remnant impressions leaving you with a very good overall eCPM.
The main fault with AdPepper from a publisher perspective is their use of the Falk AdSolution ad management system, which although is very robust and stable, is a real hassle and slow to use, with a complicated interface that prevents you taking a quick look at your stats to see how your site is performing on a constant basis. Nevertheless, the staff are always very quick to respond to queries and very helpful, offering numerous ways to contact them from email to phone to instant messenger.
Overall, Ad Pepper is a good and constantly improving network only let down by the poor usability of their current ad serving solution, something which they may take into account and consider changing soon.
