Add to ListPlease note: this plugin is officially deprecated. If you are still interested in using this service please utilize the offical Ads module included in Jetpack.
With traditional advertising relationships a publisher or blogger has two relationships and platforms–one for publishing and the other for advertising. AdControl combines the two partnerships into one.
AdControl is a new service from Automattic that extends our advertising scale and know-how to eligible sites using WordPress. We believe it is a special partnership between the largest Internet publishing platform and our users. The team at AdControl and WordPress.com are very excited about the potential to help our self-hosted publishers to earn income from their sites with high quality ads and strong rates from advertisers.
Make sure you apply to WordAds for each site you want to run AdControl on.
