Every tracked action on sessions.ca β what fires, when, and whether it's working.
Nobody could say with confidence what was being tracked. That makes every campaign result arguable, and it's how you end up optimising against a number that was never being recorded.
The full picture of measurement on the site: the event taxonomy (every action we record and what data rides along with it), the Google Tag Manager setup that fires them, and live reporting showing what's actually coming through. It's both the documentation and the proof.
