Use SiteDetour's rule building interface to easily design audiences. Each audience is intended to be a segment of your overall traffic.
For example, an audience could be defined as "All visitors outside the United States."
You are able to combine rules to create your desired level of complexity and specificity.
Once your target audiences are defined, you may combine them with any redirect rule to create logic-based redirect behavior.
For example, you could dynamically redirect visitors of your domain to a particular destination based on the country they are visiting from.
