Here at Microsoft, we want to ensure that ads serving on Bing and Yahoo! are high quality, which is why the Relevance and Quality Guidelines were developed with the goal of creating a high quality user experience. Just like all of our guidelines, relevance and quality applies to all advertisers, which creates an equal playing field. There is one particular part of the Relevance and Quality Guidelines that I continually receive questions about - sponsored ads.
As a new online advertiser or even an online advertising veteran, the best way to avoid editorial disapprovals is to make sure youre familiar with the Microsoft adCenter online advertising guidelines . These guidelines are put in place to provide a high quality search experience for users and publishers and maintain a fair marketplace for advertisers.
