Learn about campaigns and display groups.
You can group campaigns so that they all display the same posts.
For example, if you have a product page for a white cell phone and another page for the black version, you can have a Product Recommendation campaign embedded on each page. By adding both campaigns to a display group, recommendations for the white version will also scroll on the black version's page. This works for your video, text and photo posts.
Display Groups can only be created for campaigns where you selected ‘Products’ versus ‘Company’ to promote. All Company campaigns will automatically be added to the Company display group.
