Each campaign has its own set of filters, meaning it can show it’s own subset of the product data available in the advertiser.
In your campaign, click the Product Data button at the bottom of the screen.
Then, click the settings tab on the left hand side of the screen. Here you will see the data fields which you can filter by. The data fields shown will depend on the business type of your advertiser.
You can add one or more filters to whichever data fields you like. Enter the values you want to filter by.
The text entered will make it so that only products that match the filtering term will be included in the campaign. For example, if the category is filtered by “Tops” then only products which have a category value of “Tops” will be included in the campaign.
If multiple filter terms are added then items matching ANY of the filtering terms will be included in the product data for this campaign. In this example, a campaign filtering it’s category by “Tops” and “Dresses” will only show products which are either tops or dresses.
