Facebook Open Graph + Viral Share Notice

Facebook made a change recently that now prevents publishers from directly modifying Link Previews. We used to be able to pass through all of the Viral Share data (Title, Description, Image) so that when shared, your link preview looked consistent whether the user was sharing the Gleam Hosted Landing Page, or your own Landing Page.

With this change we are no longer able to edit Previews when a user Viral Shares from your own landing page (i.e. if the widget is embedded on a landing page or blog post). Instead Facebook will show the Open Graph tags associated with your page.

If you're using the Gleam Hosted Landing Page then you do not need to worry about this.

We now provide your Open Graph tags on the Code/Install tab of the campaign for you to add to any landing pages you are installing a Gleam campaign on.

You can also debug how your campaign will look when shared by putting your Landing Page into the Facbeook Debugger.

Facebook crawls these tags periodically so if you make changes you will need to use the Scrape Again option in the Debugger to refresh them.
