A short form, a pre-read built from public data and a call on the three biggest opportunities.
A written plan
Scope, tests in order, the stop rule for each test and what I need access to.
The work
A weekly review of your accounts and tests, a test roadmap and channel decisions, reported against your backend numbers with the stop rules agreed up front.
Common questions
What does a week look like?
An async review of your accounts and tests, as a recorded walkthrough plus written notes, and a monthly strategy call.
Can you help us hire?
Yes. I help hire buyers and evaluate agencies, including test tasks and what to look for in their reporting.
Do you touch the accounts?
Advisory is review and decisions, and your team runs the accounts. Hands-on buying is a different engagement.
