ConversionRuler primarily identifies visitors to a web site by setting what is known as a Cookie in a visitor's web browser.
Cookies allow ConversionRuler:
- to uniquely identify a visitor to a site
- to match their initial landing to a sale or other action
- to identify the visitor at a later date when they return to a site
