When you share the Campaign URL in a Facebook Status Update, or add a comment to a Comments Widget, Facebook adds some extra elements to the News Feed post, such as an image and a title. These elements come from special Open Graph Meta Tags that we serve to Facebook.
Checking Meta Tags
To check what values we are serving to Facebook, use Facebook’s Debugger Tool and enter your Campaign URL.
Important: If you make changes to the Meta Tags as described below, Facebook may not pick up the changes because of the way it caches Pages. You can resolve this by using Facebook’s Debugger Tool. When you enter a Campaign URL, Facebook updates its cache with the new information.
Tags and Values Provided by ShortStack
We use your Campaign name, which you can change in the Settings.
We use article. This cannot be changed.
We use your Campaign URL.
Site Name (og:site_name)
We use the name of the Facebook Page your Campaign is published to.
By default, we use the profile picture of the Facebook Page the Campaign is published to, but if you Custom Published the Campaign, you can select an image from your Media Library in the Settings.
We omit this tag by default, but for Custom Published Campaigns, you can enter a one- or two-sentence description in the Settings.
App ID (fb:app_id)
The Facebook App ID of the Custom Published Campaign.
Overriding the Share URL
When someone shares a URL to Facebook or Google+, those platforms scrape the URL for additional information. When someone shares a Campaign URL, ShortStack detects when Facebook or Google+ scrapes the URL, and make sure that Meta Tags are included with information from the Share Widget. If you use custom code to override the Share URL, ShortStack has no control over what is shared to Facebook or Google+.
