In your seller stats, you will see clicks and visitors.
Clicks are raw clicks, or how many times your buttons are loaded and displayed. The numbers can come from bots, search engines, page reloads, and many other sources.
Visitors are the unique visitors that come to your offer, distinguished by IP. Each IP is only reported once, so it is a more specific indication of how many people are viewing your page, rather than how many times your sales page is loaded.
