Want to learn all ins and outs of website tracking? First look at this list of web analytics definitions and discover how much you already know.

Bounce Rate stands for the percentage of visitors who leave the page as soon as they come to it, without paying attention on other pages.

First Visit/First Session is a visit from a person who had never downloaded the page before.

Impression – each time a prospect sees ads, it is called impression. Many website owners hire professional designers and copywriters to invent an eye-catchy banner and slogan.

Hit refers to the file request from the web server and is available only in log analysis. Very often the number of hits is considered one of the main criteria of the site’s popularity, however, such an approach may lead to the over-estimation of results. The fact is that each web page consists of many discrete files, and when the page is downloaded, all these files are considered as hits by the system. That is why the number of hits can’t be the evidence of popularity, but is about the complexity of single web pages. In order to know the actual site’s popularity it is more effective to track the total number of page views and visitors/users.

New Visitor means a user who came to the page for the first time. Basically the Bounce Rate (see above) among new visitors is higher that among repeat visitors (see below).

Page View stands for a request for the file which is determined as a web page in log analysis. As all other resources, such as .css, .js files, images etc, serving to view the page, are requested from the web server, one page view can generate many hits.

Repeat Visitor means a user who has visited the site at least once. Creating more repeat visitors is one of the main goals of everyone who operates a website.

Singletons is a metric to define the number of views when only one web page is visited.

Unique Visitor/Unique User – a person who comes to your site for the first time.

Visibility Time refers to the time during which an individual page is viewed.

Visit, also referred as Session, – a definite number of requests from a unique user. Each visit can contain multiple hits and web page views.

Visitor Recency – is the period between the recent and the current visits of a repeat visitor. Visitor Recency is usually measured in days and can be tracked by various web analytic tools
