TheDashboardMetricThatActuallyMatters

Impressions. Clicks. CTR. CPC. Conversions. Conversion rate. ROAS. CPA. Revenue. AOV.

Every dashboard shows you twenty metrics. Most people watch all of them. Very few know which one matters.

The metric: Contribution to profit after ad spend.

Not ROAS. Not revenue. Not conversions.

Contribution to profit. The money left in the bank after you've paid for the product, the shipping, the payment processing, the returns, and the ads.

Why most metrics mislead:

Revenue: Tells you nothing about margin. £100k revenue at 10% margin is worse than £50k revenue at 30% margin.

ROAS: Includes revenue you don't keep (VAT, returns, discounts). A 4x ROAS on low-margin products can be unprofitable.

Conversions: Not all conversions are equal. Some products make money, some lose it. Conversion count is vanity.

CPA: Only meaningful relative to margin. A £30 CPA is great on a £100 margin product, terrible on a £20 margin product.

How we calculate contribution:

Revenue
Minus VAT
Minus COGS
Minus shipping
Minus payment processing
Minus refunds/returns
Minus discounts
Minus ad spend
Equals contribution to profit

This number is what matters. Everything else is either a driver of this number or a distraction from it.

The challenge:

This metric requires real data from your business. Margin by product. Return rates. Actual discount application. It's not in Google Ads.

Most agencies don't have this data. So they optimise for metrics that are available but misleading.

We insist on getting this data. Because without it, we're guessing. And guessing with your money is not a service.
