When creating a proper Meta Product Catalog, you should always follow the documentation describing all requested product fields in your product feed. You can see more also in Meta documentation.
In order to get the most from your product inventory data, we strongly suggest following these best practices.
Use only replace schedule for the product
ROI Hunter is processing all the data in your source product feed and adds more (image templates, updated mapping) and then sends it to Meta. Our version of your feed is on a new URL address. We keep products in your Product Catalog fresh - we create, update and remove products based on the data in your source product feed.
Using an Update schedule would overwrite our data and would lead to issues such as missing image templates in your ads. Please don't use it.
Use the same product granularity across all platforms
If your Google Shopping product feed contains each product variant as a separate product (i.e. each shoe size is separated product), use the same granularity in your Google Analytics tracking and in your Meta product feed.
If you prefer representing all variants grouped in just one product, it can be also OK, but follow this approach on all the platforms.
Chain product variants by group ID
Using product variants is the preferred approach in both Google Shopping and Meta. To ensure that Meta does not show more variants of the same product in Carousel (i.e. same shoe in all Carousel cards), always chain the variants by group_item_id field.
Use the same identifiers across all platforms
ROI Hunter can download product performance data from Google Analytics and Google Shopping. You can also connect Additional Product Data Sources. When we download the data, we need to pair it with your products. For smooth data paring, we strongly recommend having the same retailer ID for Meta, product ID for Google Shopping, and SKU for Google Analytics.
Include Category in a structure that best describes the store
Google taxonomy is recommended for the category field, but it isn't always sufficient. We prefer being as specific as your store is (i.e. Google only has one category of shirts, but maybe your speciality shirt store is selling dress shirts / short-sleeved / over shirts / Hawaiian / linen / … /).
Provide as much information about your product inventory as possible
Use our Additional Product Data Sources (Additional Feeds) to provide us with data about your products, such as Quantity in Stock, Margin rate, COGS, etc. Using this data will help you to choose the best products to promote.
