We really love WordPress. How can you not? You can use it for the basis of a simple website, an e-commerce site or more. Add to this its extremely easy to expand via the multiple plugins system,  WordPress is almost always our first choice. To that extent we wanted to share with you our first choice for one of the best Advertising Managers you can use with WordPress. Created  by the team of OpenX, Advertising Manager is the only solution you need. You can add advertisements to your sidebar, to a post, it can incorporate other AdNetworks, include your own ads, and it can be rotated randomly all over the site. This tool is super powerful, and with other Plugins you can really customize your site in ways you never dreamed. For example we were able to use Advertising Manager on one website, adding a buy now button for different affiliates across several hundred pages using the  Exec-PHP Plugin and Custom Fields. In the end, the only limits will be your creative juices.
