On April 8, Bing announced hat is now supporting new snippet controls with robots meta tags to help webmasters manage how their search results are being displayed in Bing. These controls work via robot meta tags in HTML or X-Robots-Tag tag in the HTTP Header.

Here are three new controls that Bing is offering:

  1. “max-snippet:[number]” — This lets you specify the maximum text-length, in characters, of a snippet in search results. Here is the meta tag “<meta name=”robots” content=”max-snippet:400” />” For example, if you set the value = 0, Bing will not show a text snippet. But if you set the value = -1, then it does not specify a limit.
  2. “max-image-preview:[value]” — This lets you specify the maximum size of an image preview in search results. Here is the meta tag “<meta name=”robots” content=”max-image-preview:large” />”  For example:
    – If value = none, Bing will not show an image preview.
    – If value = standard, Bing may show a standard size image.
    – If value = large, Bing may show a standard or a large size image.
    – If value is not none and not standard and not large, it does not specify a limit.
  3. “max-video-preview:[number]” — This lets you specify the maximum number of seconds (integer) of a video preview in search results. Here is the meta tag “<meta name=”robots” content=”max-video-preview:-1” />” For example:
    – If value = 0, Bing may show a static image of the video.
    – If value = -1, it does not specify a limit.

These meta tags can be used either alone or they can be combined if you wan to control the max length of the text and video. Here is an example ​<meta name=”robots” content=”max-snippet:-1, max-image-preview:large, max-video-preview:-1, noarchive” />

Bing said, “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.” Based on this, it should be live in the upcoming weeks, probably by the end of Spring.

According to Bing, it will use these options as directive statement, not as hints.

Bing has published more help documents over here.

Google announced similar controls last September.
