A Search Engine Watch Forums post by Discovery alerts the community to the official launch of MSN ContentAds, which occurred yesterday. Every advertiser has now been pulled into the service.
As Barry mentioned earlier, you must opt out manually. To do so, Discovery has provided the following steps:
* Click the Campaigns tab.
* To change the settings for specific campaigns, select the check boxes next to those campaigns.
* Click Bulk edit.
* In the Edit settings for multiple campaigns section, from the Campaign settings drop-down list, select Content distribution, and click Apply.
Discovery also provides additional tips on separating your content ad keywords from your keywords for search or for combining them.
Tips for managing MSN ContentAds and discussion can be found at Search Engine Watch Forums.
