Hits Pageviews Visits & Unique Visits
Hits are the number of files that are accessed during a pageview and can be any where from 1 to easily 25 or more. One hit for accessing the CSS file, one hit for each JS file, one hit for each image file, one hit from each template file, and the list goes on. Hits are a useless statistic. Pageviews are the number of times any page on your site is accessed. If you divide your pageviews by your visitors you will get the average number of pages a visitor is looking at. Visits are the number that connects request pages from your site. One person could come and go to your site 100 times a day. In fact if you look at your visits by IP you will probably find your own IP address at the top of the list.
What are these stats good for?
Hits are useless except to impress people that don’t know better. Pageviews tell you the number of impressions a site-wide banner will get. Visits can be used to give you your conversion rate by dividing your site conversions by your site visits. This is a very important number to monitor.

What is SEO?
Search engine optimization (SEO) is the process of improving the volume and quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results for targeted keywords. Usually, the earlier a site is presented in the Search Engine Results Pages (SERPS) or the higher it "ranks", the more searchers will visit that site. SEO can also target different kinds of searches, including image search, local search, and industry-specific vertical search engines.
The initialism "SEO" can also refer to "search engine optimizers", terms adopted by an industry of consultants who carry out optimization projects on behalf of clients, and by employees who perform SEO services in-house. Search engine optimizers may offer SEO as a stand-alone service or as a part of a broader marketing campaign. Since effective SEO may require changes to the HTML source code of a site, SEO tactics may be incorporated into web site development and design. The term "search engine friendly" may be used to describe web site designs, menus, content management systems, URLs, and shopping carts that are easy to optimize.
