When users visit your site, they are often referred to your site via a hyperlink on another website.

This may be in the form of a link on a partner or subsidiary website, or it may be in the form of a link on a search results page on Google, Yahoo or another internet search engine. You may even discover that users accessed your site through sources that you did not know linked to your site!

There are a few scenarios for visitors who are not referred to your site from another site. In SiteAnalyze, these scenarios are collectively referred to as having "no referrer". The possibilities of accessing your site with "No referrer" are:

• The user types your site’s URL directly into the browser address field.
• The user has your site as their start page when they open their browser.
• The user has a bookmark that refers to your site in their browser.
• The user has previously visited your site and clicks on a link in their browser history.

It may be useful to disregard these visits when analysing the most useful source of traffic to your site.

Similarly, it may be useful to disregard all internal references; i.e. all references from one page on your site to another page on your site.

Filters can then be applied to display data only for traffic that arrived to your site from specific sites. This is useful to compare sources of traffic head-to-head, or to focus analysis of user behaviour for users that have been directed to your site from a specific source.
