Doors of Influence ranks growth interventions by the effort required and the size of the outcome they can plausibly create. Start with the smallest door, a campaign optimization inside the ad account. Move outward to new creative, then to a different customer avatar or message. The largest door is a purpose-built landing page and offer, because it requires coordinated choices about margin, product, bundle, and incentive while also forcing new creative and campaign setup. The method prevents a media buyer from treating every performance decline as an account-settings problem. It also makes the escalation deliberate: use a small lever for a small correction, but move to the business and offer layer when account changes cannot fix conversion or unit economics.

Core principles
- 01Match the size of the intervention to the size of the problem.
- 02Campaign settings are smaller levers than creative, audiences, and offers.
- 03A landing page and offer can change the customer and the economics together.
- 04An apparent advertising failure may originate in the business model.
How to run it
- 1
Diagnose the constraint
Determine whether performance is limited by account execution, creative, customer positioning, conversion, or economics. Do not assume an advertising symptom has an advertising cause.
Pro tip Use the smallest door capable of changing the diagnosed constraint.
Watch out Repeated account tweaks cannot repair an unprofitable offer or weak conversion.
- 2
Try the account door
Make a focused campaign optimization when the required correction is small and clearly inside the account.
Pro tip Define the signal that would show the change worked before making it.
Watch out A small operational change should not be expected to produce a business-model-sized outcome.
- 3
Open the creative door
Create a materially different message or format when existing assets are failing to earn attention or conversions.
Pro tip Change the concept, not merely the setting or a minor visual detail.
Watch out Many near-identical ads still communicate the same signal.
- 4
Open the avatar door
Position the product for a different customer type when a higher-value or better-fit buyer could support stronger economics.
Pro tip Connect the avatar change to a clear reason that customer would buy and spend more.
Watch out A new avatar still needs matching creative and a credible proposition.
- 5
Open the offer door
Build a landing page around a distinct bundle, price point, or incentive. Recalculate margin and create the supporting ads and campaign structure.
Pro tip Treat the page, offer, creative, and targeting as one coordinated entry point.
Watch out Scaling a new offer before checking its economics can amplify losses.
In the wild
Shackleford describes using purchase size to distinguish customers for a beverage brand. The team observed that customers moving from an eight-pack to a 12-pack tended to stay longer, then considered entry points ranging from roughly $30 or $40 to bulk orders around $160 or $200. Each price point required different positioning and allowed the team to measure the value of the customers it attracted.
→ The offer became a way to seek and compare customer quality, not merely a discount attached to an ad.
Common mistakes
Optimizing inside the account forever
Small campaign changes cannot solve weak conversion, inadequate margin, or an offer customers do not want.
Changing every layer at once
Simultaneous changes make it difficult to identify which door produced the result.
Ignoring downstream economics
A landing page can lift conversion while still attracting customers the business cannot profitably serve.
Is it for you?
Best for
E-commerce teams diagnosing why paid acquisition has stalled despite ongoing account optimization.
Not ideal for
Teams without enough traffic or sales evidence to distinguish account, creative, offer, and economics problems.
From the transcript
“You have to think about levers of influence at, uh, like doors, we'll call it doors of influence.”
“The biggest lever, the biggest movement is building a, a building a landing page with a unique offer to attract an individual consumer.”
