Cosgrove Growth Signal Score

Growth Signal Score

Creative is king. But your best ads may be scaling your worst customers.

A $100 customer and a $2,000 LTV customer can send the exact same “Purchase” event.

The algorithm isn’t broken. It’s doing exactly what you told it to do.

Free 4-minute Growth Signal Score. No platform access required.

Why this matters

To Meta, your best and worst customers may look exactly the same.

Customer A
First purchase$100
Lifetime value$110
Signal sent to MetaPurchase
Customer B
First purchase$100
Lifetime value$2,400
Signal sent to MetaPurchase

To Meta: the same outcome.

If customer quality, retention, upgrades, churn and downstream value never make it back to the ad platform, Meta and Google can only optimize using the first conversion they see.

More budget doesn’t fix a bad definition of success. It scales it.

Creative finds people who convert. Growth signals tell the algorithm which conversions were actually valuable.

Your team may spend every week improving creative, offers, landing pages and bids. But once someone converts, Meta and Google can only learn from the customer information you send back.

Your business may know
  • Who activated
  • Who became qualified
  • Who purchased again
  • Who upgraded
  • Who churned immediately
  • Who retained
  • Who became high-LTV
  • Which customers were actually profitable
Your ad platform may know only
“They purchased.”

The AI buying your media is only as smart as your definition of a valuable customer.

You have spent years improving the creative inputs that tell the algorithm who will respond. Growth Signal Score measures the customer signals that tell it who to find more of.

Creative quality × Signal quality = optimization quality

Creative answers
Who will respond?
Growth signals answer
Which responders should the algorithm find more of?

Your ad platforms may be learning the wrong lesson if…

  • Your best and worst customers send the same conversion event
  • Meta optimizes to purchases, but not retention or LTV
  • Your CRM knows customer quality that never reaches the ad platforms
  • Revenue develops weeks or months after the initial conversion
  • A fast-churning customer looks like a successful acquisition
  • You have server-side tracking but cannot explain what it is teaching the platforms
  • Marketing, analytics and finance disagree on which customers are profitable
  • You cannot confidently explain what each major campaign is optimizing toward today

If several of these are true, your paid media may be operating with an incomplete and potentially dangerous definition of success.
