## Feed File Specifications - MVP
Uploading a feed with the Minimum Required Data will allow the system to deliver ads and function normally, but it will be missing the following features:
- Price display in the UI (from **price value **and **price currency** fields) - advertisers find it useful to know the product price in order to set the bid, but it is not mandatory
- If **product\_group\_id** is set to the same value as **gtin**, ROAS numbers may appear lower than if product\_group\_id is set in an ideal way because cross-product attribution will not be possible
### Minimum Required Data
**Scope: **Only categories which are required for the test
| **Column** **Name** | **Required** | **Format** | **Examples / Values** | **Description** | **Content Length Limitation** |

Use the product\_group\_id attribute to group product variants in your product data.
Variants are a group of similar items that only differ in one detail such as size, color, etc.
This attribute is used for the cross-product attribution. for example attributing products with different color or size. | 50 characters
