Confused. Just visited this GA help page https://support.google.com/analytics/answer/1257084?hl=en#sessions_vs_users
. This "Users that leave your site and return within 30 minutes are counted as part of the original session." is what confuses me.
Take this example..Someone reached my website via search to the homepage, went to some other page say the About page, stayed there for 2 minutes, closed the tab. After 10 minutes, he opened Twitter, saw a tweet with a link to the same website. Clicked on it and reached the website again, all within 30 minutes.
So how many sessions? 1 or 2? How will this affect the source/medium reports? What will be the time on page for the About page, 12 minutes or 0?
