Google Analytics provides great stats for your web site, but understanding its terminology isn't simple. 
Here is a quick guide that will help you get started with some of its key phrases:

1.  'Top channels' - i.e. top sources of people coming to your web site
2. Paid search - paid google ads driving people to your site
3. Organic search - people coming to your site via google/bing without clicking on a paid ad
4. Direct - people going straight to your web site by typing in its address
5. Social - i.e. facebook or similar
6. Referral - this could be links from other web sites, or links sent by email
7. Bounce rate - percentage of people who only view one page on your site and then leave
8. Pages / session - average number of pages viewed each time someone visits your site
9. Users / vs sessions - users is the number of individual visits coming to your site / sessions also counts each visit by an individual (i.e. if a person visits your web site five times - then he would show up as '1 user' visit and '5 sessions')
10. Goal conversion - we are not using this feature for now, but it can be set to count for example how many people fill in your contact form
