When a visitor arrives at your site through a collaborator’s referral link, the “Site Visited” event is triggered. This creates an engagement linking the visitor to the collaborator who owns the link.

How it’s typically used

Site Visited is the most common engagement trigger and the one most people think of when they picture an affiliate program. A collaborator shares their link in a blog post, an email, or a social post, and every click creates or refreshes an engagement tied to that collaborator. When the visitor eventually buys something, the program has a record of who sent them.

Because it fires on every visit, Site Visited is usually paired with a “newest engagement wins” or “oldest engagement wins” sorter in the program’s settings. That’s how the program decides which collaborator gets credit when a visitor has clicked multiple links across the same session or across multiple sessions.

Where this fits

The basic affiliate program recipe uses Site Visited as its primary tracking event. It’s also the foundation for any program where the collaborator’s job is to drive traffic, whether that’s a classic affiliate relationship, a paid media partner, or an influencer who sends people through a bio link.
