A feed is a set of items uploaded or fetched from a source at once which holds all information about your products in a machine readable-format. It is required for creating product catalogs.
While creating a feed, certain rules must be followed. Otherwise, Meta won´t recognize it. To have a better idea, a basic feed in CSV format with 2 products can look like this.
Each line contains info about 1 product
Each column contains 1 information (called tag) about a product like price or condition
Each feed must contain these 9 columns:
The column name must be in English. Instructions can be in your language.
You can use additional columns to tailor Dynamic Ads to your needs. Find more information about the optional tags in the Meta documentation.
Some fields (availability, condition, and price) must contain certain values. To be specific, you can use only “new”, “refurbished” or “used” for the “condition” column. If you use “like new”, it won´t be recognized.
Do not worry. If you make a mistake in your feed, you can easily correct it in our catalog manager.
