Unique Visitor

What is a Unique Visitor?

A “Unique Visitor” is a distinct person who visits a website during a set time frame, counted only once, no matter how many times they visit. In digital advertising, this metric helps measure the reach of a website or ad campaign by showing how many different people have interacted with it. It’s useful for understanding audience size and ensuring that the content is reaching a wide, diverse group, rather than counting repeat visits from the same person.
