Estimates use the industry-standard model: each QS point above 6 reduces CPC by ~16%, each point below increases it exponentially (QS 1 ≈ +400%). Google does not publish its exact formula — treat these as directional.

## What is Quality Score and why does it matter?

Quality Score (QS) is the rating Google assigns to each keyword in your campaigns, on a scale from 1 to 10. It is not a decorative metric: it directly determines how much you pay per click and where your ads appear.

Google uses QS to calculate Ad Rank — the score that decides which ads are shown and in what position. A high QS lets you win positions while paying less than competitors with higher bids but lower relevance.

Ad Rank formula

Ad Rank = Max bid × Quality Score × Expected impact of extensions

## The three components of Quality Score

Google evaluates three signals to calculate QS. Each has a different weight and a different lever for improvement:

Expected CTR

High weight

The probability your ad receives a click when shown for that keyword, compared to other advertisers at the same position. Calculated on position-adjusted historical data, not your raw CTR. **How to improve:** work on headline copy, include the main keyword in the first headline, and activate relevant extensions.

Ad relevance

Medium weight

How well your ad message matches the search intent. A generic ad that serves many keywords will have low relevance for each of them. **How to improve:** group keywords by intent into small ad groups and write specific ads for each group.

Landing page experience

High weight

The quality and relevance of your landing page: load speed, consistency between what the ad promises and what the page delivers, ease of navigation. This is the most commonly "Below average" component and the highest-leverage fix when improved. **How to improve:** ensure the landing page matches exactly the search intent and the ad message.

## How much each QS point costs — and saves

The impact of QS on CPC is not linear — it is exponential at the low end. Moving from QS 1 to QS 5 has far more impact than moving from QS 7 to QS 10.
