Usability

Even though Tradedoubler has made a huge step in the right direction, AdSense is still better. For example, Tradedoubler forgot to translate some of the interface words into local languages. Here’s an example of a mixture of a German interface with English wordings:

Flexibility

Tradedoubler AdMatch lets you do way more stuff than Google AdSense. I like the fact that Tradedoubler also employs the product databases of its affiliate programs. However, Tradedoubler’s inventory of advertisers is minimal compared to Google’s. So even though Tradedoubler offers more in terms of looks, Google offers you way more matching ads.

Technical Performance

I’m not impressed by AdMatch’s performance. It takes longer to load than AdSense, especially when it needs to examine a URL for the first time. Also, on Internet Explorer 7.0 on my Vista machine, AdMatch fails to display the ads under certain conditions. I can see that text is moved down and space reserved by the ad, but I can just see a blank space. I could reproduce that error on another machine.

Conclusion

AdMatch is buggy! And Tradedoubler doesn’t have enough ads to be able to provide a good match for all these content sites out there. AdMatch is worth a try for those who run Tradedoubler affiliate programs already. Don’t use it if you make most of your money from contextual advertising!
