To apply content restrictions to your placement, you can add Inventory - Based Rules.
This allows you to filter and control the recommendation output using your inventory - whether you want to feature a specific category, brand, event, or filter at the product level.

⚠️ Note: Using complex tag rules may significantly impact your recommendation results.
We recommend always reviewing the output in Rec Viewer when working with advanced tag logic.

Create a New Rule 

The first step is to create a new tag rule by clicking the Add rules button and then Edit them. 

In the dropdown, you’ll see available fields from your standard inventory that you can select.

Note: Some operators work only with numeric fields — for example, "Is Between" or "Less Than" are applicable to fields like Price.

You can also create more complex rules by combining conditions using AND and OR operators.
