A unique click is defined as a click on an ad from a single computer. Everyone that clicks on the same ad once then the unique clicks and click numbers will be the same. However, it is important to keep in mind that some users click an ad more than once. Unique clicks tell marketers how many times a link was clicked. Multiple clicks by one person do not play a role in the total number of clicks. It is important to remember that there is a difference between unique clicks and total clicks. Total clicks take multiple clicks into consideration.
