Q: Where can I find the latest Bing mRSS video feed specifications, including optional and required tags?
A: We have uploaded the latest copies of the Bing mRSS video feed specification document to the Web. Click the
preceding link to download a copy to your computer.

The Bing mRSS video specification document covers optional and required tags, date/time format, and includes a
complete example of a video feed.

Q: Is there a self-serve way to get my video content indexed?
A: No. Once you have decided you want to use mRSS to upload your video content to Bing, you need to contact the Bing
mRSS support team to make arrangements for Bing to read your mRSS feeds. The Bing crawler will not automatically
find and read your mRSS files otherwise.

Q: Does creating an mRSS feed guarantee my content will be indexed?
A: No. When you contact the Bing mRSS support team about setting up a feed, they will evaluate the content on your
website and determine whether they want to include it in the Bing index. However, all owners of original content are
invited to submit feed requests to Bing.

Q: How long will it take my feed’s content to be included in the index?
A: If you are adding videos to the Bing index via mRSS for the first time, a validation process must take place. Typically,
this process can take about two weeks.

After the mRSS feed has been validated and accepted, it will take an additional 2-3 weeks for videos to be added in the
index, assuming there are no further issues detected that block implementation.

Q: How will I know when my video content is searchable using Bing?
A: It is simple to check if your site’s video content is in the Bing index. In your browser, go to
http://www.bing.com/videos/browse. Click in the Bing search bar and type the following:

site:<YourURL.com>

substituting your website’s URL (such as in site:www.msn.com), and then press ENTER. Please note that this method of
searching for your video content only provides an index estimate, and may not reflect the actual number of videos in the
Bing index. If the difference is significant, please contact the Bing mRSS support team for more information.

Q: Why should I give you a feed? Can’t you just crawl my site for the videos?
A: It is increasingly difficult for any search engine crawler to access all of your videos because they either are behind
JavaScript or appear as pop-up videos. The purpose of a feed is to allow us to easily include your video content in the
Bing index, which may otherwise have been difficult for our system to find or crawl. Submitting an mRSS feed provides
you with a higher assurance that your videos will be included in the index in a more complete and timely manner.

Additionally, providing a feed allows us to collect better metadata about your videos, which can help optimize relevance
rankings. The <media:content> tag allows us to create a smart preview of the video, which will drive higher click-through
rates to the site and provide a better overall user experience. Over time, our web crawler will improve its ability to more
thoroughly crawl video content, but for now an mRSS feed can help meet both the needs of the search engine and the
content provider.

Our ranking is based on search relevance. Bing does not give preferential treatment in its ranking based on the provider,
such as in MSN videos or video content submitted by partner feeds. The best way to optimize your video content’s

                                                               2
ranking is to include both the link to the actual video as part of the feed (using the <media:content> tag) along with
relevant, keyword-rich metadata describing the content.

Q: I’m already providing a feed to MSN Video. Do I need to provide a separate feed to Bing as well?
A: No. If you are already providing a feed to MSN Video, you do not need to provide an additional feed to Bing. The
videos you provide to MSN Video will be indexed by Bing.

Q: Can I just use Yahoo’s mRSS specification?
A: The Yahoo mRSS specification is similar to ours, but not an exact match. If all you have is the Yahoo mRSS, it will work
on a basic level. However, we recommend that you use the Bing mRSS specification since it adds several enhancements
to Yahoo’s mRSS, such as custom Bing: tags.

Q: Can I just create an RSS feed?
A: No. Generic RSS does not include the necessary metadata fields for Bing to index your video content files. Our mRSS
feeds include additional metadata that allow us to index your video content more effectively with a higher degree of
relevance.

Q: If I have a Google video sitemap feed, is that enough for Bing to index?
A: Bing supports Google’s Sitemap video extensions as long as it contains the basic, required metadata Bing needs, such
as title, video landing page, a link to the actual content, etc. The feed must conform to Google’s Sitemap schema. We
also accept incremental feeds containing your latest videos in this format. For more information, see the Google blog
article detailing the release of their Sitemap video extensions schema and feed requirements. However, note that using
this format means you will not benefit from the Bing index enhancement made in the Bing mRSS format.

Q: Can the feed I provide to Bing be processed by other search engines? Especially with the Bing: specific
tags?
A: We do not know how the other search engines will work with your Bing mRSS content feed. For these questions, you
should consult directly with representatives of the other search engines.

Q: How do you determine relevance and ranking of videos for queries?
A: Bing focuses on providing exceptional user experience when looking for videos. Some of the important tags that help
your videos discoverability are:

    •   <title>*
    •   <description>*
    •   <media:content> (referred to as the smart preview)*
    •   <media:keywords>
    •   <media:category>
    •   <media:ratings>
    •   <media:views>

* Required. Refer to the Bing mRSS video specification for the latest information.

Q: What are the benefits of providing you data for all the required tags?
A: The general rule is that the more metadata you provide in the mRSS feed, the better your content will perform in
relevant queries in Bing. Of course, quality, not just quantity, counts. The relevance of the metadata provided is key to
discoverability.

                                                             3
Q: Can you publish content in your index quickly?
A: Yes. Bing has the capability of crawling and indexing content quickly (in as little as one hour or so if needed).
Typically, these response times are reserved for time-sensitive content, such as news and current hot topics, and are
more typically updated within a day or even hours at a time.

Q: What does Bing need from me to index all of my videos? How do I update the feed or add the latest
videos?
A: In order for Bing to index all of your videos and keep adding the latest content, you’ll need to provide two separate
mRSS feeds – a full back-catalog feed (aka “full feed”) and an incremental update feed (aka “incremental feed”) as
defined in the Bing mRSS video specification document. Both feeds are accepted in either mRSS or Google Sitemap with
video extensions format. The full feed will ensure that your entire video collection is added with the right metadata.
Providing the incremental feed URL is the best way to make sure that Bing always has your latest video content. We will
also need to know how frequently videos are being added to your site (be it hourly, daily, weekly, etc.).

If you have an incremental feed available which contains the latest videos and we are not already picking it up, contact
the Bing mRSS support team and we will be glad to set this up for you.

Q: How do I remove videos out of the index so that they do not return in any search results?
A: The preferred method to delete feeds is to ensure that the <Bing:expireDate> or <dcterms:valid> tags are included in
the mRSS feed. This should be the date you want Bing to pull the video out of the search results. Alternatively, Bing also
supports using an expiration feed as defined in the Bing mRSS video specification document.

If you remove the video from your site without specifying an expiration date, or do so before the specified expiration
date, the video will remain in the index and may be included in search results. Users will get a file not found error if they
click on the video when the page or video link is no longer valid.

Q: How do I restrict access to my videos so that they are only viewable in certain countries?
A: One option is to block the content on the back-end from your servers, based on the requesting IP address, when the
user clicks on the link. The other option is to apply a restriction in your mRSS feed by adding the <media:restriction> tag
inside the <item> tag.

The following shows two examples of a video that is viewable 1) only in the U.S., or 2) in multiple, specified countries.
Use two-letter country codes to add more countries. The country code must be written in lowercase.

•   U.S. only. Countries outside of this will not be able to watch the video:

    <media:restriction relationship="allow" type="country">us</media:restriction>

•   Multiple countries. This example limits access to users in the listed countries (U.S., France, and Germany). Countries
    not listed will be unable to watch the video:

    <media:restriction relationship="allow" type="country">us, fr, de</media:restriction>

Note that restricting content to other countries via the <media:restriction> tag in mRSS is not 100% effective as the
restriction is based on the location of the requestor’s IP address.




                                                              4
Q: Can I password protect the feed I provide to Bing?
A: No. Currently, our systems are not set-up to handle password protected feeds. Microsoft and Bing will not share the
feed URLs.

Q: Can I ask Bing users to log on to my site before playing the video?
A: No. We prefer that Bing visitors do not have to log on before playing a video.

Q: Can I serve the video host page outside of Bing browser frame?
A: No. When ingesting a feed, Bing will look for the video’s <media:player> URL and ignore other attributes, such as
‘target=”_blank”’, disabling the page from opening in a new browser window.

Q: What is the maximum size for an mRSS feed file (in terms of number of video content items and/or file
size)?
A: The answer is different for full feeds, which contains all of your videos, and incremental or update feeds, which only
contain the most recent video content items added.

    •    For full feed, there is no limit on file size or number of video content items.
    •    For incremental feeds, we can only process the first 1 MB, which equates to approximately 1,000 video content
         items per incremental feed.
    •    For expired feeds, there is no limit on file size or number of video content items.

Q: How should I treat optional tags?
A: If you don’t have metadata for optional tags (such as <media:keywords>) for a specific item, then omit those tags
from that video content <item> group. Don’t include empty tags in your mRSS feed.

Q: What will happen to a feed if one or more of the video content’s required information is missing or
invalid?
A: These types of mistakes are usually found during the setup process of the feed exchange. This is an important reason
why Bing must go through feed validation and testing before any video content added to the index. If this occurs after
setup, our system will skip indexing the video content item that has missing or invalid data. If the feed contains poorly
constructed XML that forces the feed to terminate early, our team is notified and will handle it accordingly.

Q: Why do you need the video URL? Will the URL/location be exposed to the public?
A: The <media:content> URL is the link to the actual video file and is used for creating smart previews, seen in Bing
video search results, which can drive higher ranking and hits to your site. Smart preview is a short, low-resolution
preview of the video. We will analyze the video for the thumbnail, but we will not store a copy of the video. More
importantly, we will not expose the video URL to the public.

We also use the video URL to extract features that are used to determine relevance.

Q: Can I omit the video’s URL from the <media:content> tag?
A: No. The <media:content> tag, which is used to create smart previews, is a required element in the feed to Bing.

Q: Can my feed contain a new category that is not defined in the current list?
A: Bing enables partners to create new subcategories for items that are not optimally represented by those included in
our predefined list. The current category list includes:

                                                             5
    •   movie
    •   movietrailer
    •   musicvideo
    •   celebrity
    •   tvshow
    •   news
    •   adult
    •   upload
    •   sports

For example: Suppose you want to create “World News” as a new category. “World News” can be set up as a
subcategory inside our “News” category. To enable this for your item in your mRSS video feed, include the Bing video
category in addition to the new category by adding a second category tag that specifies the Bing video scheme. For
example, the two tags from our example would be constructed as follows:

<media:category>World News</media:category>
<media:category scheme="http://video.Bing.com/scheme">news</media:category>

Q: Why should I have different text in the <description> and <title> tags?
A: In the Bing search engine results page (SERP), each video is accompanied by a smart preview, along with its title
underneath. If you toggle between the Grid view and List view, you will see that Bing displays <title> information in both
views, but only shows <description> tag information in List view.

Note: The icons for Grid view and List view respectively are located in the upper right margin just below the search bar,
following the text, Sort by: best match | most recent (          ).

In addition to providing more context to the reader, the benefits of having unique text in the <description> and <title>
tags plays an important role in determining relevance to end user video search queries.

Q: What is wrong with my date and time values?
A: Date and time values are used in <pubDate>, <origReleaseDate>, <expireDate>, and <dcterms>. The first three tags
use the same format and are where most error occurs. The tag <dcterms> uses a different date/time format.

The correct syntax for <pubDate>, <origReleaseDate>, and <expireDate> is:

Day, dd mm yyyy hh:mm:ss zzz

which stand for Day of the week, date day, month, year, hour, minute, second, and time zone (or differential from GMT).
An example of <pubDate>, <origReleaseDate>, and <expireDate> syntax for date and time would look like the following:

<pubDate>Tue, 13 Nov 2007 18:20:45 PST</pubDate>

An example of <dcterms> syntax for date and t6ime is as follows:

<dcterms:valid>end=2007-10-17T17:00+01:00;</dcterms:valid>

   •   For <dcterms>: http://dublincore.org/documents/dcmi-period/

Q: I still have questions. How can I contact a Bing representative?
A: Please use Bing Content Feed Support email address bingfeed@microsoft.com for all video feeds questions and
follow-ups.

DOCUMENT INFO
Description: mRSS is a data feed not unlike normal RSS feeds. However, mRSS offers custom tags associated specifically with media content metadata, and that extra information about each item of content can make a big difference in the way content is ranked in the Bing index. Getting more specific information about video content enables Bing to have greater confidence in associating its relevance to the keywords you use in your descriptions, and thus it can improve your content's rank in queries using those keywords. And by using mRSS to submit your video content to Bing, you get a higher assurance that your content collection may be added to the Bing index more thoroughly and more quickly. Note, however, that video content does not get preferential ranking because it came from an mRSS feed. It's the keyword relevance derived from the metadata you supply in the mRSS feed that makes the difference.
