Set up heatmaps in PageSense to see where users have clicked more, how far they've scrolled, and on which parts of a page they've spent the most time using color-coded patterns in reports.

Measure customer engagement with your web forms

Use form analytics in PageSense to see how people interact with different fields in your form, whether they complete the form successfully or not, and where exactly they drop out on your form.
