If you have a web page that reviews a claim made by others, you can include
ClaimReview structured data on your web page. ClaimReview structured
data can enable a summarized version of your fact check to display in Google Search results
when your page appears in search results for that claim.
This guide describes the details on how to implement ClaimReview structured data.
If you don’t want to add structured data manually, you can check out the
Fact Check
Markup Tool. To learn more, visit
About the Fact Check
Markup Tool.
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, thenoindextag, 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.
Example
Imagine a page that evaluates the claim that the earth is flat. Here is what a
search for “the world is flat” might look like in Google Search results if the page
provides a ClaimReview element (note that the actual visual design may change):

Here’s an example of structured data on the page that hosts this fact check:
Eligibility guidelines
Google doesn’t guarantee that fact checks will be shown in search results, even if your page is
marked up correctly according to the Rich Result Test. Using structured data enables a feature to be present,
it does not guarantee that it will be present. The Google algorithm programmatically
determines the eligibility for fact check rich results, depending on many variables, including
the following guidelines.
For your fact check content to be eligible to display as a fact check rich result on Google
Search, you must meet the following guidelines:
- Your site must have several pages marked with
ClaimReview
structured data. - You must follow all the structured data
guidelines and Search Essentials. - There must not be any mismatch between the structured data and page content (for example, if the
structured data indicated that the claim is true, but the content on the page said the
claim was false). Instead, make sure that both the content and structured data match (for
example, both indicate that the claim is true). - You must meet the standards for accountability, transparency, readability, and site
misrepresentation, as articulated in our
Google
News General Guidelines. - You must have a corrections policy or have a mechanism for users to report errors.
- Websites for political entities (such as campaigns, parties, or elected officials) aren’t
eligible for this feature. - Your readers can easily identify the claims and checks in the body of the article. Your
readers are able to understand what was checked and what conclusions were reached. - You must clearly attribute the specific claim that you’re assessing to a distinct
origin (separate from your website), whether it’s another website, public statement, social media, or other
traceable source. - Your fact check analysis must be traceable and transparent about sources and methods, with
citations and references to primary sources.
Technical guidelines
- To be eligible for the single fact check rich result, a page must only have one
ClaimReviewelement. If you add multipleClaimReview
elements per page, the page won’t be eligible for the single fact check rich result. - The page hosting the
ClaimReviewelement must have at least a brief summary
of the fact check and the evaluation, if not the full text. - A specific
ClaimReviewmust only be on one page on your site. Do
not repeat the same fact check on multiple pages, unless they are variations of the same
page (for example, you can post the sameClaimReviewon the mobile and desktop
versions of a page). - If your website aggregates fact-check articles, ensure that all articles match the
criteria and that you provide an open and publicly available list of all fact-check websites
you aggregate.
Structured data type definitions
The following structured data types are required to implement fact checks:
You must include the required properties for your content to be eligible for display as a rich result.
You can also include the recommended properties to add more information about your content,
which could provide a better user experience.
ClaimReview
The full definition of ClaimReview is available at
schema.org/ClaimReview.
The Google-supported properties are the following:

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.
Как мы это применяем
Fact check markup requires a genuine editorial process behind it. We implement it only for clients who actually run one, since the credibility cost of misusing it exceeds any visibility gain.
