Bing has announced new controls for webmasters to better control the site's snippets used in bing search.
It's extending support for robots.txt, or X-Robots-Tag tag in the HTTP Header for content preview.
max-snippet:[number]
Specify the maximum text-length, in characters, of a snippet in search results.
max-image-preview:[value]
Specify the maximum size of an image preview in search results.
max-video-preview:[number]
Specify the maximum number of seconds (integer) of a video preview in search results.
The NOSNIPPET meta tag is still supported and the options above can be combined with other meta robots tags.
Example < meta name="robots" content="max-snippet:-1, max-image-preview:large, max-video-preview:-1, noarchive" / >
Over the following weeks, we will start rolling out these new options first for web and news, then for images, videos and our Bing answers results. We will use these options as directive statement, not as hints.
