Session data

To calculate and predict engagement, attention span and stickiness, Unless collects behavioral data for each visitor session.

Whenever a website visitor views one or more web pages that are operated by one of our customers, Unless collects a set of data about the visitor session. It does not contain elements that may identify an individual directly.

A session is a group of user interactions with a website, that take place within a given time frame. A single session can contain multiple page views. Session data is primarily used for analyzing and predicting the following:

  • Visitor engagement;
  • Visitor attention span;
  • Website stickiness.
