Step 1: Get Adflow feed URL
First, go to Adflow and copy the Catalog URL
Step 2: Go to Meta Business manager
Navigate to this link: https://business.facebook.com/products
Stap 3: Add supplementary Feed
Go to the original catalog you would like to update with Adflow's images and click 'Add Supplementary feed'.
Please note: This will override the plain product images with the winning design. Once applied, it will automatically add your new design to all running campaigns.
Once successfully imported, you can navigate to product collections or products to view the new imported Adflow designs.
Note: After importing, your old images may still be visible under products or product sets. Facebook is still compiling the feed. Depending on the size of your feed, this can take up to several hours.
You now have best of both worlds: Years of learning in the original catalog + Your improved design.
Now keep track of your campaign's performance to see the lift in results.
