## Targeting visitors based on rules

To add the rules click on "Add rules"

Each rule has three parts:  an attribute, an operator and the value/s. For example, if you want to target a group of visitors from India then you can have a rule as Country  IS\_ONE\_OF  India

A rule can have multiple conditions where the visitors need to satisfy all the conditions. For example, if you want to target a group of visitors from India and the device type is Desktop then you can have a rule as Country  IS\_ONE\_OF  INDIA and Device Type IS\_ONE\_OF Desktop
