Google’s Ad Manager is now out of beta. It looks like my WP125 plugin has some competition now. Okay, okay, it’s not really in the same category as WP125. Sure, they both manage ads, but mine does so from within WordPress, and is designed to make 125×125 ads as easy as possible, while Google’s service is designed to offer as much power as possible, while keeping the interface clean.
Google’s offering is more advanced, at the expense of usability. Google Ad Manager is intended more toward the audience that OpenX has. For people who want to manage CPM/CPC ads, or ads simply with a start/end date. Google Ad Manager allows you to define various ad zones, with a wide variety of ad dimensions (including 125×125 and custom sizes).
Overall Google’s offering looks like a very good way to manage ads. It seems powerful, and the interface is clean and reasonably easy to use. If you’re looking for a full-scale ad server to handle ads across a medium to large site, this is an option well worth considering. It’s overkill for an ordinary blogger looking to sell 125×125 ads.
If you have a Google Account, all you have to do is go to google.com/admanager/ and login to start using the service.
