The Incrementality Playbook: How to Stop Paying for Conversions You Already Own
A practical playbook for affiliate and performance marketing teams who need to prove what the channel is worth. Built from Acceleration Partners’ real-client frameworks, it lays out the four-step methodology to audit, define, plan, and track incrementality, plus a real client case study and the questions to ask before you spend another dollar on partners who capture demand instead of creating it.

03
How to define incrementality
- “Incremental” means something different for every business. Here are three questions to answer first.
04
Why this matters more now

Real client examples
