Tracker setup checklist before you spend a cent

Tracker setup checklist before you spend a cent
Trench note: launching without clean tracking = lighting money on fire blindfolded. Run this.

— Postback fires a TEST conversion end-to-end. Don't trust 'it should work.'
— Tokens passing: source ID, widget/site ID, creative ID, GEO. If you can't see widget ID, you can't optimize.
— Cost passing in (CPC or CPM) so ROI is automatic, not manual math.
— Redirect chain under 2 hops. Every hop leaks clicks.
— Mobile redirect tested on a real phone, not just desktop devtools.
— S2S, not pixel, wherever the network allows.

Break tracking and your whole data set is fiction.
Go test it.
