As part of the setup of PureClarity, you will decide on the best place to place your Behavioral Merchandising Zones (BMZs) - see Merchandising Zones Placement - Best Practice Guide. You need to define your BMZs within PureClarity. This can be done under the "Configuration" section in the Admin console by selecting "BMZs."
Here you can give user-friendly names to BMZ ids, e.g. Hero Banner for HP-01.
You are able to change the ID of a BMZ even if there is content set against the existing ID, and the existing content will be automatically assigned to the new ID. This may take a few minutes to be changed across the system. Please note that you will need to change the reference tag to the new ID on your website.
