When a link is shared to a Facebook page, Facebook will first check to see if the link is coming from a verified domain, and then they’ll check to see if the Facebook page is allowed to edit link previews for that page.
Domain Verification is the process of telling Facebook that you own the website. Once verified, Facebook will allow you to edit the previews from that website.
Here is a help article from Facebook that explains how to set it up.
🔔 Note: Domain verification allows preview customization for links from the verified domain only.
Set up your domain verification
Step 1: Add your domain to Facebook Business Manager
Click on Settings (bottom-left).
Click on Brand Safety in the left side panel and choose Domains.
Click on Add and enter your domain in the pop-up
Step 2: Verify the domain by following the instructions from Facebook. Fill in the domain you want to verify and apply one of the following steps:
Add a meta-tag to your HTML source code
Upload an HTML file to your root directory
Update the DNS TXT record with your domain registrar
Click 'Verify' if you applied one of these methods.
Step 3: Assign your Facebook page to the newly verified domain
From the Domains page, click on Add Assets.
A window will pop up where you can select the Asset Type. You should see your page listed there. In the right-hand pane, select your page as the asset.
Click Add to associate your page with your domain. You'll now see it listed under Connected Assets
Step 4: Once verified, you can go back to your StoryChief account and modify the preview for the Facebook social post. You can follow the steps described in this help article.
🎉 You're done, grab a coffee, you deserve it!
