Visits & Visitors
A visit happens when someone or something (robot) visits your site. It may consists of one or more page views/ hits. One visitor can make multiple visits to your site.
Visits represent the number of individual sessions initiated by all visitors to your site. If a user is inactive on your site for 30 minutes or more, any future activity will be attributed to a new session. Users that leave your site and return within 30 minutes will be counted as part of the original session.

A session is defined as a series of page requests from the same uniquely identified client with a time of no more than 30 minutes. In other words, a session ends when someone goes to another site, or 30 minutes elapse between pageviews, whichever comes first. A visit ends only after a 30 minute time delay. If someone leaves a site, then returns within 30 minutes, this will count as one visit but two sessions. In practice, most systems ignore sessions and many analysts use both terms for visits. Because time between pageviews is critical to the definition of visits and sessions.
