When a user visits a web page, Google Analytics registers that as a new session. Both the visitor's actions on the site and the session details are recorded. Pages / Session is the average number of pages viewed by a visitor during a session. It represents how many pages on a website users view on average during a session. It is an important metric for webmasters. If the rate is low, this might show that the web page is not interesting enough for users or there are other issues. If a proper analysis is performed and the underlying issues are addressed, users might choose to spend more time on the website and view more pages.
