What is an Engagement?
Any track-able event where a potential customer's action is tied to a collaborator.
Last updated: April 10, 2026
An engagement is any trackable event that ties a potential customer’s action to a collaborator. The classic example is a visitor arriving at your site through an affiliate link, but engagements cover a much wider range of interactions: an existing customer watching a course lesson made by an instructor, a reader landing on a blog post written by a partner, a coupon code being applied at checkout. If a measurable thing happens on your site and you can tie it to a collaborator, Siren can record it as an engagement.
Engagements are the connective tissue between customer behavior and collaborator credit. Without them, conversions would have nowhere to attach.
Example: a site visit
Customers can trigger many engagements
A customer’s journey can include many engagements with different collaborators or repeated interactions with the same one. Each engagement carries the point value defined by the program it belongs to.
A visitor might click an affiliate’s link, return a week later through a different collaborator’s coupon code, then finally check out. By the time they convert, multiple collaborators have engagements on file, and the program structure decides which ones win.
A multi-engagement journey
This is what makes multi-touch attribution possible. If you want every collaborator who contributed along the way to share in the reward, see the multi-touch sales attribution recipe.
Engagement triggers
Different programs use different engagement triggers depending on what behavior you want to reward. Site visits and coupon usage are the most common, but Siren also supports course completions, lesson completions, blog post visits, form submissions, and manual attribution for cases where you need to assign credit by hand. See Site Visited and the related trigger pages for the full list.
