What Is Quality Score in Google Ads and How It Works

The Quality Score in Google Ads is a rating from 1 to 10 that measures how relevant and useful your ads, keywords, and landing pages are to users. It affects your ad position and cost per click, helping Google show better ads to people searching.

How It Works

Think of Quality Score as a report card for your ads. Google looks at how well your ad matches what people are searching for, how often people click on your ad compared to others, and how good your landing page is. If your ad is very relevant and helpful, Google gives you a higher score.

This score helps Google decide which ads to show first and how much you pay when someone clicks. A higher Quality Score means your ad can appear in a better spot and cost less per click, just like getting a discount for being a good student.

Google combines three main parts to calculate this score: expected click-through rate (how likely people are to click your ad), ad relevance (how closely your ad matches the search), and landing page experience (how useful and easy your website is after clicking).

Example

This simple example shows how you might calculate a basic Quality Score based on three factors, each rated from 1 to 10, then averaged.

python

def calculate_quality_score(expected_ctr, ad_relevance, landing_page_experience):
    """Calculate average Quality Score from three factors."""
    score = (expected_ctr + ad_relevance + landing_page_experience) / 3
    return round(score, 1)

# Example values
expected_ctr = 8  # Expected click-through rate
ad_relevance = 9  # How relevant the ad is
landing_page_experience = 7  # Quality of landing page

quality_score = calculate_quality_score(expected_ctr, ad_relevance, landing_page_experience)
print(f"Quality Score: {quality_score}")

Output

Quality Score: 8.0

When to Use

Use Quality Score to improve your Google Ads campaigns by focusing on relevance and user experience. If your score is low, it means your ads or landing pages might not be matching what users want, so you should update your keywords, ad text, or website.

Marketers use Quality Score to lower costs and get better ad placements. For example, if you run an online store, improving Quality Score can help your ads show higher when people search for your products, making your ads more effective and affordable.
