Discussion forum (DiscussionForumPosting
) structured data
![An illustration of the discussions and forums feature](https://developers-dot-devsite-v2-prod.appspot.com/static/search/docs/images/discussions-and-forums-rich-result.png?authuser=7)
Discussion forum markup is designed for any forum-style site where people collectively share first-hand perspectives. When forum sites add this markup, Google Search can better identify online discussions across the web and make use of this markup in features such as Discussions and Forums and Perspectives.
How to use DiscussionForumPosting
within a forum
In general, we recommend nesting comments under the post they relate to. If the forum has its own threading structure, use a tree of comments to represent its structure:
{ "@context": "https://schema.org", "@type": "DiscussionForumPosting", "headline": "Very Popular Thread", ... "comment": [{ "@type": "Comment", "text": "This should not be this popular", ... "comment": [{ "@type": "Comment", "text": "Yes it should", ... }] }] }
If it's more linear in nature (for example, an original post followed by a series of replies), nest them all under the original post as comments. Ideally, later pages of content in multi-page forums include the original post with the main page URL:
{ // JSON-LD on non-threaded forum at https://example.com/post/very-popular-thread/14 "@context": "https://schema.org", "@type": "DiscussionForumPosting", "headline": "Very Popular Thread", // Only the headline/topic is explicitly present "url": "https://example.com/post/very-popular-thread", ... "comment": [{ "@type": "Comment", "text": "First Post on this Page", ... },{ "@type": "Comment", "text": "Second Post on this Page", ... }] }
If the URL is primarily about a single post, use mainEntity
(or mainEntityOfPage
) to identify the primary
DiscussionForumPosting
:
{ "@context": "https://schema.org", "@type": "WebPage", "url": "https://example.com/post/very-popular-thread", "mainEntity": { "@type": "DiscussionForumPosting" ... } }
For web pages that have a list of posts (for example, on a profile, topic, or category page), it's common that they don't have all the information present on the same page and require the user to click to get the extra information (like replies). It's up to you whether you choose to include only the information that is present on the page (and include the URL to the discussion-specific posting).
Don't mark one post on the page as a main entity if it's not a discussion page for the
post. To show that pages are a related set of posts, it might be useful to attach them
all to a
Collection
or ItemList
.
How to add structured data
Structured data is a standardized format for providing information about a page and classifying the page content. If you're new to structured data, you can learn more about how structured data works.
Here's an overview of how to build, test, and release structured data.
- Add the required properties. Based on the format you're using, learn where to insert structured data on the page.
- Follow the guidelines.
- Validate your code using the Rich Results Test and fix any critical errors. Consider also fixing any non-critical issues that may be flagged in the tool, as they can help improve the quality of your structured data (however, this isn't necessary to be eligible for rich results).
- Deploy a few pages that include your structured data and use the URL Inspection tool to test how Google sees the page. Be sure that your page is
accessible to Google and not blocked by a robots.txt file, the
noindex
tag, or login requirements. If the page looks okay, you can ask Google to recrawl your URLs. - To keep Google informed of future changes, we recommend that you submit a sitemap. You can automate this with the Search Console Sitemap API.
Examples
The following markup example shows a non-threaded, linear forum page:
<html> <head> <title>I went to the concert!</title> <script type="application/ld+json"> { "@context": "https://schema.org", "@type": "DiscussionForumPosting", "mainEntityOfPage": "https://example.com/post/very-popular-thread", "headline": "I went to the concert!", "text": "Look at how cool this concert was!", "video": { "@type": "VideoObject", "contentUrl": "https://example.com/media/super-cool-concert.mp4", "name": "Video of concert", "uploadDate": "2024-03-01T06:34:34+02:00", "thumbnailUrl": "https://example.com/media/super-cool-concert-snap.jpg" }, "url": "https://example.com/post/very-popular-thread", "author": { "@type": "Person", "name": "Katie Pope", "url": "https://example.com/user/katie-pope", "agentInteractionStatistic": { "@type": "InteractionCounter", "interactionType": "https://schema.org/WriteAction", "userInteractionCount": 8 } }, "datePublished": "2024-03-01T08:34:34+02:00", "interactionStatistic": { "@type": "InteractionCounter", "interactionType": "https://schema.org/LikeAction", "userInteractionCount": 27 }, "comment": [{ "@type": "Comment", "text": "Who's the person you're with?", "author": { "@type": "Person", "name": "Saul Douglas", "url": "https://example.com/user/saul-douglas", "agentInteractionStatistic": { "@type": "InteractionCounter", "interactionType": "https://schema.org/WriteAction", "userInteractionCount": 167 } }, "datePublished": "2024-03-01T09:46:02+02:00" },{ "@type": "Comment", "text": "That's my mom, isn't she cool?", "author": { "@type": "Person", "name": "Katie Pope", "url": "https://example.com/user/katie-pope", "agentInteractionStatistic": { "@type": "InteractionCounter", "interactionType": "https://schema.org/WriteAction", "userInteractionCount": 8 } }, "datePublished": "2024-03-01T09:50:25+02:00", "interactionStatistic": { "@type": "InteractionCounter", "interactionType": "https://schema.org/LikeAction", "userInteractionCount": 7 } }] } </script> </head> <body> </body> </html>

Guidelines
For your discussion forum structured data to be eligible for usage in Google Search, you must follow these guidelines:
Content guidelines
- Only use
DiscussionForumPosting
markup to describe a user-generated post on a website. Don't use this markup for content that's primarily authored by the publishers of the website or their agents. - If your site is more like a generic social media platform, you can use
SocialMediaPosting
, which is the parent type ofDiscussionForumPosting
, with the same requirements. - While we encourage valid markup of other types (
Article
,ImageObject
,VideoObject
) that can use very similar markup with comments, author information, interaction statistics, those should not useDiscussionForumPosting
markup. Here are some examples:Valid use cases:
- A community forum page where users can talk about a certain game
- A generic forum platform hosting a wide variety of subforum content
- A social media platform where users can post and reply to comments or media
Invalid use cases:
- An article or blog written directly by an agent for the website (even with comments)
- User reviews about a product
- Note that for most of Google's use cases, a Q&A page is considered a special case of a
discussion forum page. If the structure of the forum website is primarily questions with answers,
we recommend that you use Q&A markup
instead. If the structure is more general and isn't usually question and answer
content,
DiscussionForumPosting
would be a better choice. - Make sure each
DiscussionForumPosting
includes the entire text of the post and make sure eachComment
includes the entire text of the response if it's found on that page.
Technical guidelines
- Unlike our general structured data preference, we recommend providing the
DiscussionForumPosting
markup in Microdata (or RDFa) if possible. This prevents you from needing to duplicate large text blocks inside markup. However, this is just a recommendation, and JSON-LD is still fully supported.

Monitor rich results with Search Console
Search Console is a tool that helps you monitor how your pages perform in Google Search. You don't have to sign up for Search Console to be included in Google Search results, but it can help you understand and improve how Google sees your site. We recommend checking Search Console in the following cases:
- After deploying structured data for the first time
- After releasing new templates or updating your code
- Analyzing traffic periodically
After deploying structured data for the first time
After Google has indexed your pages, look for issues using the relevant Rich result status report. Ideally, there will be an increase of valid items, and no increase in invalid items. If you find issues in your structured data:
- Fix the invalid items.
- Inspect a live URL to check if the issue persists.
- Request validation using the status report.
After releasing new templates or updating your code
When you make significant changes to your website, monitor for increases in structured data invalid items.- If you see an increase in invalid items, perhaps you rolled out a new template that doesn't work, or your site interacts with the existing template in a new and bad way.
- If you see a decrease in valid items (not matched by an increase in invalid items), perhaps you are no longer embedding structured data in your pages. Use the URL Inspection tool to learn what is causing the issue.
Analyzing traffic periodically
Analyze your Google Search traffic using the Performance Report. The data will show you how often your page appears as a rich result in Search, how often users click on it and what is the average position you appear on search results. You can also automatically pull these results with the Search Console API.Troubleshooting
If you're having trouble implementing or debugging structured data, here are some resources that may help you.
- If you're using a content management system (CMS) or someone else is taking care of your site, ask them to help you. Make sure to forward any Search Console message that details the issue to them.
- Google does not guarantee that features that consume structured data will show up in search results. For a list of common reasons why Google may not show your content in a rich result, see the General Structured Data Guidelines.
- You might have an error in your structured data. Check the list of structured data errors and the Unparsable structured data report.
- If you received a structured data manual action against your page, the structured data on the page will be ignored (although the page can still appear in Google Search results). To fix structured data issues, use the Manual Actions report.
- Review the guidelines again to identify if your content isn't compliant with the guidelines. The problem can be caused by either spammy content or spammy markup usage. However, the issue may not be a syntax issue, and so the Rich Results Test won't be able to identify these issues.
- Troubleshoot missing rich results / drop in total rich results.
- Allow time for re-crawling and re-indexing. Remember that it may take several days after publishing a page for Google to find and crawl it. For general questions about crawling and indexing, check the Google Search crawling and indexing FAQ.
- Post a question in the Google Search Central forum.
