Joel Liu's List: Learning google analytics

Analytics measures both visits and visitors in your account. Visits represent the number of individual sessions initiated by all the 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.

The initial session by a user during any given date range is considered to be an additional visit and an additional visitor. Any future sessions from the same user during the selected time period are counted as additional visits, but not as additional visitors.

A pageview is defined as a view of a page on your site that is being tracked by the Analytics tracking code. If a visitor hits reload after reaching the page, this will be counted as an additional pageview. If a user navigates to a different page and then returns to the original page, a second pageview will be recorded as well.

A unique pageview, as seen in the Top Content report, aggregates pageviews that are generated by the same user during the same session. A unique pageview represents the number of sessions during which that page was viewed one or more times.

Say I have 10 visits to a page, 4 of which are entries. 6 people exit,
including all 4 of the people who landed on that page. My bounce rate
would then be 100% , but my overall Exit is still only at 60% because
most of the visitors from other pages stayed on site. Hope I
understood your question - though I'm not sure this answer helped any!

• Head Match: If your URL is always the same for this step of your funnel, but is followed by unique session or user identifiers, use the Head Match filter and leave out the unique values.
   
    For example, if the URL for a particular user is 'www.example.com/checkout.cgi?page=1&id=9982251615' but the 'id' varies for every other user, enter 'www.example.com/checkout.cgi?page=1' and select Head Match as your Match Type.
   
   
 
• Regular Expression Match: Uses regular expressions to match your URLs. This is useful when the stem, trailing parameters, or both can vary between users. For example, if a user could be coming from one of many subdomains, and your URLs use session identifiers, use regular expressions to define the constant element of your URL. For example, 'page=1' will match
    'sports.example.com/checkout.cgi?page=1&id=002,'  as well as
    'fishing.example.com/checkout.cgi?page=1&language=fr&id=19.'
