Determining unique visitors is not an exact science and everyone has their own formula for doing so. With that in mind, we use the following method:
- Cookie tracking: Our server adds a tracking cookie when a visitor clicks on your link. This cookie is timestamped so we can compare their last visit to their current visit. Visitors without a tracking cookie are counted as unique.
- Visit intervals: Once a tracking cookie is set, we won’t count repeat visits within a 30 minute window as unique. If a visitor clicks your link one hundred times in rapid succession, we’ll count the first click as unique and the other 99 as non-unique. If a visitor clicks your link once then returns and clicks it the next day, we will count that as two unique visits.
