Geo Tracking

Post Affiliate Pro lets you manage your affiliate programs in a variety of ways. In particular, the sophisticated Map Overlay feature is ideal for businesses looking to acquire new customers in multiple regions as it allows you to see where your visitors are located and how visitors from different locations behave. With this information affiliate marketers can modify their affiliate marketing strategies and use features such as Geo Targeting to target specific audiences based on geographical location.

To further help with their marketing goals, Post Affiliate Pro gives marketers a GeoFencing feature, which sets virtual fences over specific geographic areas and targets everyone who enters the fence. This is a powerful tool for small business owners or for businesses with multiple branches. Either way, you can maximize your ROI without risk of losing hard earned revenue.
