September 2022

September 20: Added the Google Site Verifier user agent.
September 13:
- Major update to Product structured data documentation to document requirements for eligibility to Merchant Listings experiences based on structured data. See the blog New Search Console Merchant Listings report: expanding eligibility with Product structured data for details.
- Re-added the itemReviewed.datePublished property. This was removed accidentally as part of the previous update to the Fact Check structured data documentation.
September 9: Removed the datePublished property from the Fact Check structured data documentation. Currently, the ClaimReview publish date isn't used in the Fact Check rich result.
September 2: Migrated the documentation about the file types Google can index from the Search Console Help Center (the content hasn't changed).
September 1: Added more examples to show how meta descriptions could be improved.

August 2022

August 31: Added a note on the use of JavaScript to add, change, or remove meta tags on a page to the list of meta and inline tags Google Search understands.
August 29:
- Added the full list of supported academic values for educationalLevel in the Learning video structured data documentation.

August 24:
- Added content guidelines to the Education Q&A structured data documentation.
- Removed references to the deprecated International Targeting report in Search Console. The recommendations described in our documentation about managing multiregional sites and localized versions of your pages remain relevant.
August 22: Updated the Article structured data documentation to reflect that Article markup is open to all types of pages (as announced in 2020 with the page experience update).
August 11: Removed our documentation about rich-media files, such as Silverlight and Flash. Turns out it's not 2005 anymore.
August 10:
- Added the gtin12 property to the Product structured data documentation. This has been supported; it's a documentation change only. Clarified that you can use the generic gtin property for all GTINs, but we recommend that you use the most specific one if possible.
- Updated the dynamic rendering documentation to explain that this isn't a recommended solution, and is a workaround if you have no other choice. Instead we recommend server-side rendering, static rendering, or client-side rendering with hydration.
August 9: Added best practices for feeds to the Follow feature documentation. We recommend that you:
- Use a descriptive title for your RSS feed, just like you would for a web page.
- For multiple feeds, we recommend that you use a single feed. Both methods are still supported, but we clarified that a single feed is easier for you to maintain and for users to subscribe to your feed.
August 8: Clarified that we don't support the URL form for GTINs in Product structured data. Make sure to use the numerical GTIN form.
August 5: Added documentation about the pros and cons enhancement for editorial product review pages.

July 2022

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.

June 2022

June 30: Added information about using JavaScript to inject canonical link tags.

May 2022

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.

May 10:
- Added new Education Q&A documentation.

January 21: Added a new robots meta tag, indexifembedded, to the robots meta tag documentation. Learn more about the new tag in our blog post.
January 20: Added a note describing how to specify Car markup and still have Product review snippet feature eligibility.
January 18: Removed guidance about specifying a range for the cookTime, prepTime, and totalTime properties in the Recipe documentation. Currently, the only supported method is an exact time; time ranges aren't supported. If you're currently specifying a time range and you'd like Google to better understand your time values, we recommend updating that value in your structured data to a single value (for example, "cookTime": "PT30M").

December 2021

December 16: Converted our old blog post about intrusive interstitials into guidelines. There are no substantial changes compared to what we have in the blog post.

- HowTo: description.
- QAPage: mainEntity.suggestedAnswer.author, mainEntity.dateCreated, mainEntity.suggestedAnswer.dateCreated, mainEntity.acceptedAnswer.author, mainEntity.acceptedAnswer.dateCreated, and mainEntity.author.

October 15: Added a requirement that the author.name field in Review snippets must be less than 100 characters to be eligible for use in Search features.

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:
- Control your title links in search results: Created a new page to describe how to control title links in search results. Introduced a new term, title link, for the title of a search result on Google Search and other properties to help clarify when we mean the title link in search results versus a <title> element on a web page. Added examples of how Google may adjust title links. There aren't any changes to the best practices for writing descriptive <title> elements.

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.

- Removed redundant sections from our documentation about how Google handles robots.txt.

- Improved the troubleshooting sections across all structured data feature guides (for example, the Product structured data guide).
- Added more beginner-friendly information about how to get started with structured data.

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.
Currently, Google is working with a wide range of providers to ensure that the use of Clip structured data works well at scale (our interest form is closed, as we have reached capacity). You're welcome to read the documentation and implement Clip structured data in advance. Keep in mind that Google doesn't guarantee that your structured data will show up in search results, even if your page is marked up correctly according to the Rich Results Test.
