\n ratings—things that may be more helpful than text snippets when it comes to deciding what
\n you want to eat. Alternately, or perhaps you’re looking for a concert nearby, and are able to
\n check out the events directly in the search results. These are made possible by publishers marking
\n up their pages with
\n structured data<\/a>.\n<\/p>\n
\n results shown are relevant to their search and why the user would want to visit the linked pages.
\n However, we recognize that site owners may wish to independently adjust the extent of their
\n preview content in search results. To make it easier for individual websites to define how much or
\n which text should be available for snippeting and the extent to which other media should be
\n included in their previews, we’re now introducing several new settings for webmasters.\n<\/p>\nLetting Google know about your snippet and content preview preferences<\/h2>\n
\n introducing a set of methods that allow more fine-grained configuration of the preview content
\n shown for your pages. This is done through two types of new settings: a set of robots<\/span> meta<\/code> tags
\n and an HTML attribute.\n<\/p>\nUsing robots<\/span>
meta<\/code> tags<\/h2>\nmeta<\/code> tag is added to an HTML page’s <head><\/code>, or specified via the
\n x-robots-tag<\/code> HTTP header. The robots<\/span> meta<\/code> tags addressing the preview content for a
\n page are:\n<\/p>\n\n
nosnippet<\/code>
\n
\n This is an existing option to specify that you don’t want any textual snippet shown for this
\n page.\n <\/li>\nmax-snippet:<\/code>[number]
\n
\n New! Specify a maximum text-length, in characters, of a snippet for your page.\n <\/li>\nmax-video-preview:<\/code>[number]
\n
\n New! Specify a maximum duration in seconds of an animated video preview.\n <\/li>\nmax-image-preview:<\/code>[setting]
\n
\n New! Specify a maximum size of image preview to be shown for images on this page, using either
\n none<\/code>, standard<\/code>, or large<\/code>.\n <\/li>\n<\/ul>\n<meta name=\"robots\" content=\"max-snippet:50, max-image-preview:large\" \/><\/code>\n<\/p>\nmeta<\/code> tags will become effective in mid-to-late October 2019 and may
\n take about a week for the global rollout to complete.\n<\/p>\nUsing the new data-nosnippet HTML attribute<\/h2>\n
\n data-nosnippet<\/code> HTML attribute on span<\/code>, div<\/code>, and
\n section<\/code> elements. With this, you can prevent that part of an HTML page from being
\n shown within the textual snippet on the page.\n<\/p>\n<span>Harry Houdini<\/span> is undoubtedly the most famous magician ever to live.<\/code>\n<\/p>\ndata-nosnippet<\/code> HTML attribute will be start affecting presentation on Google
\n products later this year. Learn more in our
\n developer documentation for the robots<\/span> meta<\/code> tag,
\n x-robots-tag<\/code>, and data-nosnippet<\/code><\/a>.\n<\/p>\nA note about rich results and featured snippets<\/h2>\n
\n structured data<\/a> is
\n eligible for display as
\n rich results in search<\/a>. These
\n kinds of results do not conform to limits declared in the above meta robots settings, but rather,
\n can be addressed with much greater specificity by limiting or modifying the content provided in
\n the structured data itself. For example, if a
\n recipe<\/a> is included in structured data,
\n the contents of that structured data may be presented in a recipe carousel in the search results.
\n Similarly, if an event is marked up with structured data, it may be presented as such in the
\n search results. To limit that presentation, a publisher can limit the amount and type of content
\n in the structured data.\n<\/p>\n
\n previews may prevent your content from appearing in these areas.
\n Featured snippets<\/a>,
\n for example, requires a certain minimum number of characters to be displayed. This can vary by
\n language, which is why there is no exact max-snippets<\/code> length we can provide to ensure
\n appearing in this feature. Those who do not wish to have content appear as featured snippets can
\n experiment with lower max-snippet<\/code> lengths. Those who want a guaranteed way to
\n opt-out of featured snippets<\/a>
\n should use nosnippet<\/code>.\n<\/p>\nThe AMP Format<\/h2>\n
\n including eligibility for more prominent presentation of thumbnail images in
\n search results<\/a> and in the
\n Google Discover feed<\/a>. These
\n characteristics have been shown to drive more traffic to publishers’ articles. However, publishers
\n who do not want Google to use larger thumbnail images when their AMP pages are presented in search
\n and Discover can use the above meta robots settings to specify max-image-preview<\/code> of
\n standard<\/code> v\u0259 ya none<\/code>.\n<\/p>\n
\n we display globally. We hope they make it easier for you to optimize the value you get from Search
\n and achieve your business goals. For more information, check out our
\n developer documentation on meta<\/code> tags<\/a>. Should you
\n have any questions, you can
