Traditional, text-only, search result snippets aim to summarize the content of a page in our
search results. Rich snippets (shown above) allow webmasters to help us provide even better
summaries using structured data markup that they can add to their pages. Today we’re introducing a set of
guidelines
to help you implement high quality structured data markup for rich snippets.
Once you’ve correctly added structured data markup to you site, rich snippets are generated
algorithmically based on that markup. If the markup on a page offers an accurate description of
the page’s content, is up-to-date, and is visible and easily discoverable on your page and by
users, our algorithms are more likely to decide to show a rich snippet in Google’s search results.
Alternatively, if the rich snippets markup on a page is spammy, misleading, or otherwise abusive,
our algorithms are much more likely to ignore the markup and render a text-only snippet. Keep in
mind that, while rich snippets are generated algorithmically, we do reserve the right to take manual
action (for example, disable rich snippets for a specific site) in cases where we see actions that hurt
the experience for our users.
To illustrate these guidelines with some examples:
- If your page is about a band, make sure you mark up concerts being performed by that band, not
by related bands or bands in the same town. - If you sell products through your site, make sure reviews on each page are about that page’s
product and not the store itself. - If your site provides song lyrics, make sure reviews are about the quality of the lyrics, not
the quality of the song itself.
In addition to the general
rich snippets quality guidelines
we’re publishing today, you’ll find usage guidelines for specific types of rich snippets in our
Help Center. As always,
if you have any questions or feedback, please tell us in the
Webmaster Help Forum.
Comment nous l'appliquons
We archive Search Central announcements because client questions often trace back to a change that was announced years ago. Reading the original is faster than reconstructing it from second-hand summaries.
