Look inside first
Real pages from the file. No blurred teaser, no locked preview.
How it opens
Every attribution model tells you which touchpoint to credit for a sale that already happened. None of them tell you whether the sale would have happened anyway. That second question is the only one that matters when you are deciding whether to keep spending.
That is page one, unedited. The remaining 5 sections carry the thresholds, the tables and the fixes.
Who this is for
- You sit over growth across several channels
- You lead marketing for an ecommerce brand
- You own a DTC or ecommerce brand
Where this came from
Not theory and not a summary of someone else's blog post. Every checklist here came out of an account I actually run, and the thresholds are the ones I use on a Monday morning.
- 100+
- Ecommerce accounts run
- $300k–$2.5M
- Monthly spend managed
- $0

Questions
What does it cost?
Nothing. There is no paid tier behind it and no call to book at the end.
What format is it?
A audit pdf you can download and keep. It opens on a phone.
What happens to my email address?
It goes on my list so I can send you the writing. I do not sell it or share it, and every email has an unsubscribe link.
Do I need to be running Google Ads already?
No. Plenty of this applies before you spend a dollar, and knowing the thresholds up front is cheaper than learning them live.
