Quality Score Diagnoser

Quality Score is not a vanity metric, it is a discount or a tax on every click. See what your score is really costing you, which of its three parts is to blame, and how much you would save by fixing it.

The short version: Google rewards a high Quality Score with lower costs, so a low score means you pay a premium on every click. Enter your Quality Score and CPC and this tool estimates how much that premium is costing you and how much you would save at a higher score, then pinpoints which component, expected CTR, ad relevance or landing page experience, to fix first.

Diagnose your Quality Score and its cost

Enter your score and CPC, then rate the three components so we can tell you which to fix first. All in your browser.

What you get

A dollar figure on something most advertisers treat as abstract. Quality Score is effectively a discount Google gives relevant advertisers, so a low score means you quietly pay a premium on every single click. This tool estimates that premium, shows how much you would save by lifting your score to a realistic target, and diagnoses which of the three components, expected click-through rate, ad relevance, or landing page experience, is dragging you down, so your effort goes where the score and the savings actually move.

How it works

  1. Enter your current Quality Score and average CPC (add monthly clicks for a total saving).
  2. Rate the three components as below average, average or above average.
  3. See your estimated CPC premium and potential savings.
  4. Open the diagnosis to see exactly which component to fix first.

Why Quality Score is really a price, not a grade

It helps to stop thinking of Quality Score as a report card and start thinking of it as a price. Google wants to show relevant ads, so it effectively charges less to advertisers it trusts to be relevant and more to those it does not. That means two advertisers competing for the same position can pay very different amounts, and the one with the higher score keeps the difference. Improving your score is one of the few levers that lowers your cost without lowering your reach: better, tighter ads lift expected click-through rate and relevance, and a faster, matched landing page lifts the experience score, and your effective cost per click falls for the same visibility. This tool turns that abstract idea into your number, and tells you which lever to pull.

Frequently asked questions

What is Quality Score?
A 1-10 rating based on expected click-through rate, ad relevance and landing page experience. It influences how much you pay per click and where your ads show, higher generally means lower costs.
How does it affect CPC?
Roughly inversely: a higher score tends to mean a lower price for the same position, because Google discounts advertisers it considers more relevant. A low score is a tax on every click.
What is a good Quality Score?
7+ is generally healthy, 8-10 strong. 5 or below usually signals a real relevance or landing-page problem worth fixing.
Which component matters most?
Whichever is below average for you. This tool flags your weakest one and tells you how to lift it.
Can improving it really cut costs?
Yes. Better relevance and landing pages typically lower your effective CPC for the same positions, so the same budget buys more clicks.
Is it free?
Yes, free with no login, calculated in your browser. Share your details once to open the diagnosis and savings.
