GUIDES

Field guides

These guides are documentary: they explain what to verify and give you a protocol you can run on your own funnel. We state clearly what we have not tested ourselves, and no result is claimed without a test behind it.

Funnel purchase tracking

A protocol to test whether one purchase is counted once, across browser pixels, server events, reloads and upsells.

Mobile funnel speed

A script-by-script protocol for measuring how tracking and personalization tags affect your mobile capture page, and deciding what to keep.
