A visitor to your web site is typically a human being, manipulating a web browser to retrieve information and accomplish tasks on a web site.
A visitor can be a person:
- sitting at a home desktop computer screen
- using a cell phone or other mobile device
- using an internet-enabled device such as a Wii, or television-enabled web browser
A visitor can also be a computer:
- A "User" cookie which identifies the visitor across sessions and never changes.
- A "Session" cookie which identifies the visitor during their session, and expires after 30 minutes of inactivity.
Visitors vs. Human Beings
In the following cases, a visitor is not equivalent to a single human being:
- Two or more people share a common computer; their activities and behaviors on the same site are not identical.
- One person has more than one internet device and accesses the internet from multiple places:
- Person visits a site at work, then purchases a product from the same site at home
- Person does research from a cell phone, then purchases from a desktop computer
