Using the Markup Tool to add ClaimReview to your Fact Checks

This section shows you how to add the ClaimReview markup to your fact checks using the Fact Check Markup Tool.

Let’s say you’ve performed a fact check and confirmed  that planet Earth is not flat, but is indeed round.

Log in to the Fact Check Markup Tool. The top section displays the URL of your organization. It is marked “read only” and cannot be edited. The URL should point to your fact check article.

Enter the publishing date for your fact check article and the name of your organization.

In the first box, enter a description of the claim that you are reviewing, the date it was made, and in the space marked Claim appearance, enter the URL (or URLs) where it was published. Claim author is the name of the person, organization or other entity who made the claim. Rating text is where you state your assessment of the truthfulness of the claim.

When finished, click Create to add the markup to the article.

We’ve developed a range of guides and documents to help you set up and use ClaimReview.
