This plugin allows blog authors to enter their Google Adsense Publisher ID and have ads displayed on their own posts generating revenue. What this means is that blogs having multiple authors can now divide revenue on that site on a fixed ratio since their Adsense ads will be loaded as well.
Installing the plugin is easy. You can set the admin publisher ID and individual authors can set their IDs in WP-Admin itself, which ensures that there is no messy editing of files.
Admins can set the ratio of how much their ads are displayed to that of author ads. However, one feature lacking is to customize this ratio by user. Currently you’re stuck with a fixed ratio, so you can’t give your better performing users higher preference over others.
