What is Account Efficiency Score?

The Account Efficiency Score is a 0–100 composite summarizing what share of an account's spend produced at least one conversion in the reporting window — the inverse of the Waste Leakage Rate.

Why it matters

The category breakdown tells you what to fix; the efficiency score tells you how urgently. It is a health signal, deliberately not an action trigger on its own.

How ClickCatalyst detects it

The score is (1 − leakage rate) × 100. An account with 1.6% leakage scores 98/100. Bands: 90–100 means strong efficiency where fixes are targeted, not systemic; 70–89 means structural improvements will move the needle; below 70 means intervene before scaling any budget.

A high score can still hide specific leaks — the case-study account scoring 98/100 was still bleeding $285/month in recoverable waste — which is why the score is always reported with the term-level detail behind it.

efficiency_score = (1 − wasted_spend ÷ total_spend) × 100

Bands: 90–100 strong · 70–89 moderate · < 70 critical

Example

A 98/100 account with one search term burning $98 at zero conversions: efficient overall, and still leaving money on the table — both facts are true, and the report says both.
