Hello Honda750,
With Microsoft adCenter, you have two ways to display your ads to potential customers who use the Internet: Search Ads (Ads that are displayed on a Bing results page in response to a user’s search query.) and Content Ads
(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 the
content network, your ads are displayed on webpages with relevant
content. As a result, you extend your advertising reach to a broader
segment of your target audience.
By default, ad groups are configured to display ads on both the search and content networks.
Microsoft adCenter is based on relevancy so the system will recongizes what you are advertising and display your ads accordingly. For example if you are selling "honda parts" it will not display your ads on any health related sites.
I hope this answers your question.
Thank you,
Microsoft Advertising Support
