Campaign URLs and Facebook
This is especially important on Facebook, which does not support campaigns on mobile browsers or their mobile app. Even if you've published the campaign to your Facebook Page, users on mobile browsers who attempt to access a campaign from its Facebook URL (e.g., http://www.facebook.com/MyPage?v=app_999999999) are redirected to the Timeline of the Facebook Page that campaign is published to. Further, Facebook does not display the thumbnails of custom campaigns installed to Pages on its mobile site.
ShortStack-generated Campaign URLs detect whether a visitor is accessing the campaign from a desktop/laptop, or from a mobile device. Visitors on desktops/laptops are shown the campaign as it appears on Facebook. Mobile visitors, however, are redirected from Facebook to the mobile version of the campaign on our servers.
Remember that if you publish a campaign, then un-publish and re-publish it, the Campaign URL will change, and any link to your campaign will no longer function. To make changes to a campaign while retaining its Campaign URL, simply make your edits in the Campaign Builder and click Publish Changes without un-publishing the campaign.
