What is the difference between Visits, Visitors and Pageviews
Visits = It is total number of unique sessions(30 min per session) initiated by your visitors.
Visitors = The number of unique users that visit your site on a daily basis. Any sessions from the same user on the same day will be aggregated into a single visitor, but may represent two or more separate visits. If a user is browsing your complete website or all pages of your website then the report will show only 1 visitor for that day.
Pageviews = Total no of page view for a particular URL. If a visitor hits reload after reaching the page, this will be counted as an additional pageview, in this case you will see Pageview=2 for that URL. If a user navigates to a different page and then returns to the original page, a second pageview will be recorded as well and total pageviews will be 3.
