Your HomeScout dash (XomePro) includes multiple widgets to help you see which contacts are interacting with your website the most.
The Active Leads/Clients widget lets you know which contacts have recently logged in.
The dash also includes widgets that will show you which contacts are actively saving properties and searches.
You may also track activity within any individual contact record.
Knowing which contacts are actively engaged and are getting serious about their home search will help you identify the best and most immediate opportunities in your pipeline.
