Analyzing user behavior can play a pivotal role in converting a lead to a customer. The more you know about your potential customers, the better you can predict (and create) the right message for them, and increase the chance of conversions.
User behavior analytics helps you identify how visitors behave at various touch points and give specific insights into their behavior patterns. Armed with this information you can segment your leads based on common characteristics, personalize promotional activities and improve their overall user experience.
