Google updated some documentation today:

• Added more supported properties for Discussion Forum and QA Page markup to provide more clarity on comment thread structure to prevent misinterpretation of how Google handles forum and Q&A content.

◦ There's a new property: `digitalSourceType` to indicate when content was created by AI. If that property is absent, Google assumes the content is human-created.

◦ `commentCount` is now a recommended property for both types of markup. It should include the total number of comments on a post/answer even if they're not all in the schema markup.

◦ And more - this SEJ article gives a rundown of all the changes.

• Added a note on the robots meta tags documentation about how Google Search processes robots meta tags outside the HTML head. Behavior hasn't changed, it just wasn't documented before.

◦ The note says: "Google Search doesn't enforce placement of meta robots in the HTML head and will respect robots meta tags in the body section of an HTML document as well."
