Segments are subsets of products filtered by tag or collection
You can create segments with Flexify based on the collection handle or Shopify tag. Once defined, you can then use these segments on Facebook to create product sets & run ads specifically per segment. Some examples:
- Create an ad that will only show product tagged with "sale" on Shopify.
- Create two separate ads each targeting their own specific collection.
More info about the Product Segments is available here.
