Facebook does not allow to edit titles and preview links to prevent fake information

Up to now, any Facebook Page when posting links can change the title, content and images that appear on the News Feed when editing the Link Preview. This allows false believers to 'read' readers into articles they don't want to read, or make it look like the real news page is posting untrue articles. It can also help real sites edit content to match the audience and update Preview when the news content changes.

To deal with fake news, Facebook starts disabling the editing feature of links posted on Page Composer or API, except for some mainstream news sites.

The new tab in Page Publishing Tools for Link Ownership will allow these exempt sites to fill in the web domain they own, then be authenticated by Facebook to have the right to edit the link preview on this domain. All pages that want this exemption must be approved before September 12, 2017, when Facebook completely eliminates the right to edit the preview of the link when Page has not been authenticated.

Facebook said 'First we will bring this feature [Link Ownership] to newspapers like news, sports and entertainment because we realize many of these pages have edited the article link of self'. Webmasters can still change the Open Graph bookmark on their pages and try checking with the Open Graph Debugger to change the default preview for the article.

Edit the view before attaching a link to help view Facebook pages

At F8 in April, Facebook mentioned modifying the preview of the link to both the API but did not provide a solution for many Pages still relying on Link Preview to optimize the content.

This change will allow Facebook to remove some of the previous structures that helped spread fake news without a valid review of the content. Methods like this and many of Facebook's other News Feed algorithms help them support real news.
