Pages/Visit shows you the average number of pages visitors view on a site within a session.
Similarweb calculates Pages/Visit by dividing the total number of page views by the total number of visits.
For most websites, the goal is to keep users engaged, nurture their interest, and encourage them to take the next step. Use this metric to understand how likely are users to complete the website goal (page views, purchase, etc.).
Why does a site have extremely high "pages per visit"?
This type of behavior is something we do come across from time to time. It usually occurs when sites use some methods/technologies to automate content loading and are especially common for shopping and eCommerce sites. In addition to auto-loading, some sites have URLs that change each time a user selects a different color/size when looking at a product. This causes requests to be resent, which we detect as clicks/events with our data collectors.
