visitor
The term is sometimes confused with unique visitor . The difference is that one unique visitor visiting a site repeatedly over a period of time will show up on the site's log file as many visitors. The term therefore refers to the number of times people visit a site - not the actual number of people visiting a site.

vortal
The term is used to describe portals that focus on one specific (vertical) topic. In other words, they target at a specific group of people - like programmers, SEO specialists etc. - by providing in-depth information on that topic.
