Data about the usage of a website, recorded by the server which hosts the site. Web statistics are usually inaccurate, so trends are more useful than absolute numbers.
Conversion rate. The ratio of enquiries, sales or other specified actions to the total number of unique visitors to a website.
Hit. A download request made to the server on which the site resides. To display a complete web page, the server needs to download a number of unique electronic files, such as image files. A hit is recorded for each download. As the number of hits is not equal to the number of visitors, it provides little useful information about traffic to a website.
Traffic. An overall term for the activity on a website, such as where your site visitors come from, which pages they visit, and which pages they leave from.
Unique visitor. A single person, defined by the IP address (an identifying number) of their computer, who visits a website during a defined period. For example, if you visit the same website three times this month using the same computer, you will be counted as one unique visitor for the month.
Web analytics is a specialised area of website statistics that focuses on understanding how people interact with a website after they have arrived.
