Feeds allow Bing to easily learn about the videos on your website. The purpose is to help Bing include your video content in the Bing index, which may not have otherwise been discovered by Bing’s web content crawlers. Submitting a feed provides you with a higher assurance that your videos will be included in the index in a more complete and timely manner. In addition, the feed can provide Bing with rich descriptions (i.e. metadata) about your videos that can be helpful for better understanding by users.
The Bing Media feed specification is an optimized media RSS (mRSS) feed for inclusion in the Bing Video index. It specifies three types of video feeds : full back-catalog feeds (aka “full feed”), incremental update feeds (aka “incremental feed”), and expire feeds. All three have different purposes, but all share the same structure and format. The Bing mRSS video specification document covers optional and required tags, date/time format, and includes a complete example of a video feed.
