What is a "Page"?
Since pricing for web development is usually based on a per page rate, it is important to understand the difference between "page links" and "outbound links".

An outbound link takes you out of the site.  A page link takes you to another page within the site.  We will need to develop that page, therefore there is a charge for it.  There is no charge for outbound links.

See the example below for clarification.
