Google Improves Forum and Q&A Search Data

Google has enhanced its structured data capabilities for forum and question-and-answer pages, introducing new properties that allow webmasters to better define reply threads, quoted material, and the origin of content. This refinement is designed to help the search engine more accurately interpret user-generated discussions and Q&A sections, reducing potential misunderstandings in how this content is indexed and displayed.

The specific updates involve two key documentation areas. For Q&A pages, the schema now supports the `commentCount` and `digitalSourceType` properties. For forum posts, the `DiscussionForumPosting` markup gains support for `sharedContent`, in addition to those same two properties. These additions provide a more granular way to describe page content for search engines.

Within Q&A structured data, the `commentCount` property can be applied to questions, answers, and individual comments. This allows site owners to indicate the total number of replies in a thread, even if every single comment is not individually marked up. For clarity, the sum of `answerCount` and `commentCount` should reflect the complete tally of all replies.

A particularly notable addition is the `digitalSourceType` property. This offers a method to signal whether content was generated by an automated system. Webmasters can specify `TrainedAlgorithmicMediaDigitalSource` for output from sophisticated models like large language models, or `AlgorithmicMediaDigitalSource` for content from simpler automated processes. If this property is omitted, Google will assume the content is human-generated.

For forum posts, the new `sharedContent` property enables the identification of the primary item being shared within a post. Acceptable values include standard content types like `WebPage`, `ImageObject`, or `VideoObject`, as well as references to another `DiscussionForumPosting` or `Comment`. This is useful for clearly marking when a post is primarily a quote, repost, or link share.

These changes are significant for sites that rely heavily on community interaction. Platforms with active forums, support communities, user-generated content hubs, and dedicated Q&A sections now have more precise tools to guide Google’s understanding. The improvements can help the search engine better differentiate between official answers and general comments, accurately count replies across paginated threads, and recognize when a post’s core purpose is to share an external link, media file, or quoted reply. The official documentation for these schema updates was revised on March 24.
