With Microsoft adCenter, you have two ways to distribute your ads: as Search Ads (Ads that are displayed on a Live Search results page in response to a user’s search query.) and Content Ads (Beta) (Ads that are displayed on Microsoft-owned websites, such as MSN Tech & Gadgets, Money, Real Estate, and Windows Marketplace, as well as participating partner websites.) . When you run your ads on content-based webpages, your ads are displayed beside relevant content. As a result, you extend your advertising reach to a broader segment of your target audience.
On the Select a campaign page, select the campaign that contains the ad group that you want to work with.
On the Select an ad group page, select the ad group that you want to distribute on content-based webpages.
On the Manage selected ad group page, click Edit ad group settings.
Under Select where your ads are distributed, select the Content network check box.
Click Save.
Notes
To ensure that your ads are displayed, select at least one network.
If you do not see the Content network check box, it's most likely because you've selected a market and language other than English - U.S. Currently, Content Ads (Beta) is only available in the United States.
