The new 0.9.6.x branch of Ad Injection has the following new features:
- Ad rotation / A:B split testing support for random, top, bottom and widget/sidebar adverts.
- Alternate content which can be defined for users who are dynamically blocked (by IP or referrer) from seeing adverts.
- Choose which paragraph to start the random ads via the UI.
- Dynamic features (ad rotation, and ad blocking by IP/referrer) now work with W3 Total Cache and WP Cache (as well as the already supported WP Super Cache).
The most significant change is the new ad rotation support. You can define multiple adverts and set a percentage for how often you want them to be shown.
