Diving center: cost per lead dropped from ₺304 to ₺131 in 4 weeks

Fake conversion tracking was rebuilt from scratch, budget leaking to wrong cities was cut, and the campaign structure was redesigned. The result: cost per lead cut by more than half, and 3x more daily leads.

The numbers are real account data; the business name is withheld for client confidentiality.

Situation

When I took over the account, reports showed a "conversion rate" of 67%. In reality, what was being counted as conversions were page views; phone calls and WhatsApp messages were not measured at all.

The real cost per lead was around ₺304, and roughly half the budget was going to clicks from cities the business could not serve.

Diagnosis

The measurement chain was wrong end to end: double counting, wrong tags, phantom conversions. There was not a single reliable number to base decisions on.

Geographic targeting was producing roughly ₺4,400 of wrong-city spend per month. The campaign structure made no distinction between search intents.

What was done

  • Measurement rebuilt from scratch: only real phone calls and WhatsApp messages count as conversions.
  • 41 geographic negatives added; wrong-city spend cut off.
  • Campaign structure rebuilt around search intent.
  • Budget increases tied to a data-gated ladder: no proof, no budget increase.
  • Managed the website relaunch; the conversion jump on switch day was verified by measurement.

Lesson

Measurement first, optimization second. Every optimization made on top of broken measurement only scales the mistake.
