* Define unlimited AdSense ad styles for use in your WordPress blog posts.
* Use multiple, different AdSense blocks within a single post.
* Enable/disable individual ad blocks with two clicks.
* Enable/disable where ads are shown (home page, post pages, archives, search pages, etc.)
* Change ad styles globally from the control panel.
* Includes an AdSense Preview tool within the AdSense-Deluxe control panel for quickly viewing the ads Google would place on a given web page.
* WordPress 1.5+ compatible (requires 1.5 or later)
* Simple installation, no understanding of plugin code or PHP required.
* [naturally, ...] it’s free!
I’ve not tested it so can’t comment on how good it is – but it seems to have some good features.
Thanks to William for the tip
