There are many options for integrating ads into Wordpress, the solutions for which will vary depending upon your particular needs, but for most scenarios there are a few key points you will want to hit:
- Dynamic ads that will change between each page load so you don't see the same ad in the same place all the time.
- Easily editable ads. You want to be able to swap ads in and out at a moment's notice.
- Support for plain images and links, as well as code snippets like the kind generated by Google AdSense.
