  • July 19: Standardized how we refer to headings and title text on the page. Previously we used the word headline, but that can be confusing in other languages.
  • July 13: Updated the User Agent string for AdsBot Mobile Web. If you hardcoded the old value in your code, update the string to avoid potential bugs.
  • July 7: Added a new page for Google Search ranking updates. This is not new information; it's a compiled list of things we've previously confirmed on our blog or on Twitter.
  • July 6: Reorganized the navigational structure to be based on topic instead of level. Removed duplicate guides that were aimed at basic or beginner level, as these documents were duplicating guidance already explained in the SEO Starter Guide.
  • July 4: Clarified that you must add three courses to be eligible for the Course rich result. This is not a new requirement; it was previously only documented in the Carousel documentation.

  • May 31: Removed the Job training structured data documentation. We initially tested this markup with a group of site owners, and ultimately found that it wasn't useful for the ecosystem at scale. This change doesn't affect any other features that may use Job training markup. You can leave the markup on your site so that search engines can better understand your web page.
  • May 22: Added transparency guidelines for video thumbnails. Ensure that at least 80% of your thumbnail pixels have little or no transparency to enable video indexing.

April 2022

  • April 14: Consolidated our How Search Works documentation for site owners by merging the basic, beginner, and advanced versions into one central document. While we cleaned up the language slightly, we haven't added anything new to the How Search Works documentation.

October 2021

  • October 28: Removed the following structured data fields from documentation, since they are unused by Google Search and Rich Result Test doesn't flag warnings for them:
    • HowTo: description.
    • QAPage:, mainEntity.dateCreated, mainEntity.suggestedAnswer.dateCreated,, mainEntity.acceptedAnswer.dateCreated, and .
    • SpecialAnnouncement: provider, audience, serviceType, address, and category.
  • October 15: Added a requirement that the field in Review snippets must be less than 100 characters to be eligible for use in Search features.
  • October 13: Clarified that VideoGame is not a valid node type for Software Apps. To make sure that your Software App is still eligible for a rich result appearance, co-type the VideoGame type with another supported type.
  • October 8: Updated our documentation about titles and snippets in Google Search results. There are now two separate documents that explain each of these search result features:

July 2021

  • July 30: Added technical, content, and quality guidelines to the Math solver guidelines and removed solution page markup instructions to make it easier for site owners to get their math solver site on Search. It is fine to remove any existing solution page markup.
  • July 29: Added a new case study about how MX Player boosted organic traffic 3x by maximizing video discoverability on Google.
  • July 28:
    • Removed guidance about hosting multiple factchecks per page. To be eligible for the single fact check rich result, a page must only have one ClaimReview element.
    • Added details about signed exchange cache lifetime.
  • July 26: Added a requirement that priceRange fields in Local business must be less than 100 characters to be eligible for use in Search features.
  • July 22:
    • Added example use cases for the FAQ guideline about hidden content on the page. The user must be able to access the answer on the page, and clicking an expandable section to view the answer is a valid use case.
    • Removed the @id property from the Local business documentation. The url property alone is a sufficient identifier to understand the local business.
  • July 21: Added a set of new documentation about Google search operators.
  • July 13: Added a new editorial guideline to the JobPosting documentation. Added a new optional property for directApply.

April 2021

  • April 19: Added new documentation for how to Get started with signed exchanges on Google Search. Learn more about the signed exchange (SXG) announcement in our blog post.
  • April 8: Added a new quality guideline to the Discover documentation. Discover focuses on interest-based feeds (for example, articles and videos), and filters out content that might confuse readers (for example, Discover might not recommend job applications, petitions, forms, code repositories, or satirical content that's removed from its original context).
  • April 7: Updated the Video structured data documentation to state that the thumbnailUrl property must use one of the supported Google Images file formats. Previously, the documentation didn't include WebP and SVG.
  • April 1: Clarified the key moments feature. Google Search tries to automatically detect the segments in your video and show key moments to users, without any effort on your part. Alternatively, there are two ways that you can manually tell Google which timestamp and label to use: Clip structured data and updating the description of a YouTube video.

March 2021

  • March 29: Removed the interest form for the Key moments feature. The feature remains in development with a select group of providers, but the program is no longer accepting submissions.

  • March 24:
  • March 17: Updated the video best practices to more clearly emphasize the important guidelines. Removed duplicate content and updated the screenshots.
  • March 16: Based on user feedback, we added more examples for the max-snippet robots meta rule, and also specified for each tag what Google's default behavior is when the tags are omitted.
  • March 11: Added new beta properties to the JobPosting structured data documentation. You may not see any appearance or effect in Google Search right away, as we are still developing how we are using this information.
    • educationRequirements.credentialCategory
    • experienceRequirements
    • experienceRequirements.monthsOfExperience
    • experienceInPlaceOfEducation
  • March 8: Added the JP_E-CODE value as an accepted value for the PropertyValue property in the Book documentation.
  • March 1: Removed instructions for submitting sitemaps on Google Sites from the sitemap guide. Google Sites doesn't create a sitemap for sites anymore.

February 2021

  • February 8: Removed the page about joining the 3D and AR Early Adopters Program. The feature remains in development with a select group of providers, but the program is no longer accepting submissions.
  • February 2: Removed the documentation for cross-language search results. This page was specific to an experimental approach with a small group of providers, and we're removing the page because it's obsolete.
