Google Ads Quality Score: Types, Importance, and How to Improve It

In the world of Google Ads, most marketers know that setting the right budget and choosing the right keywords are key to running successful campaigns. But what often gets overlooked is a powerful hidden metric that directly affects ad performance and cost: Google Ads Quality Score.

If you've ever wondered why your ads aren't ranking well—or why you're paying more than competitors for the same keywords—the answer may lie in your Quality Score. In this guide, we'll break down what Quality Score is, the different types, why it matters, and what you can do to optimize it.

What Is Google Ads Quality Score?

Google Ads Quality Score is a score ranging from 1 to 10 assigned by Google to each keyword in your account. It reflects how relevant and useful your ads, keywords, and landing pages are to people seeing your ads. A higher score means Google sees your ad as more helpful to users.

The score is based on three primary components:

• Expected Click-Through Rate (CTR): How likely your ad is to be clicked when shown.
• Ad Relevance: How closely your ad matches the searcher's intent.
• Landing Page Experience: How useful and user-friendly your landing page is for visitors who click your ad.

Each of these components is rated as “Below Average,” “Average,” or “Above Average.” These ratings contribute to your keyword-level Quality Score and ultimately affect where your ad appears and what you pay per click.

Why Quality Score Matters

Improving your Quality Score doesn’t just improve your ad rank—it can also lower your cost-per-click (CPC), increase your return on investment (ROI), and improve your ad visibility.

Here’s how Quality Score benefits your campaign:

• Lower CPC: A high score allows you to pay less than competitors for the same ad position.
• Better Ad Positions: Higher scores contribute to a better Ad Rank, placing you higher in search results.
• Increased ROI: Lower costs and higher conversion potential mean more return from your ad spend.
• Level Playing Field: Even smaller advertisers with smaller budgets can compete if they focus on ad quality.

How to Check Quality Score in Your Google Ads Account

Google lets you see Quality Score at the keyword level. Here’s how to access it:

Types of Quality Score

Google doesn't just use one single Quality Score across your account. There are several layers, each influencing performance differently:

1. Keyword-Level Quality Score

This is the score you can view in your dashboard. It's specific to each keyword and is based on how well your ad and landing page match the intent behind that keyword.

How to improve:

• Match ad copy to keyword intent
• Use relevant landing pages
• Improve CTR with better calls-to-action

2. Ad Group-Level Quality Score

This is the average Quality Score of all keywords in an ad group. If some keywords are pulling the average down, the whole group may perform poorly.

Tips:

• Group similar keywords together
• Align ad text with group themes
• Remove low-performing keywords

3. Campaign-Level or Account-Level Quality Score

This is not visible in the interface, but Google uses your overall account performance as a signal when assigning scores to new keywords.

Improve it by:

• Maintaining consistent performance
• Avoiding large volumes of irrelevant keywords
• Regularly cleaning up underperforming ads

4. Ad-Level Quality Score

This isn’t displayed as a number, but ads that are highly relevant and engaging contribute positively to the Quality Score of the associated keywords.

Optimization advice:

• A/B test headlines and descriptions
• Include keywords in the ad text
• Use clear and benefit-focused messaging

5. Landing Page Experience Score

This component assesses how well your landing page answers the user’s query. It’s a big factor in the total score.

Improve it with:

• Fast load times (under 3 seconds)
• Mobile responsiveness
• Relevant content that matches the ad
• Easy-to-use navigation

6. Display Network Quality Score

For display campaigns, Google also evaluates ad relevance and performance across placements.

Optimize by:

• Using responsive display ads
• Targeting audiences precisely
• Excluding poor-performing placements

How Google Calculates Quality Score

Although Google doesn’t reveal the exact formula, research suggests approximate weights:

• Expected CTR: 39%
• Landing Page Experience: 39%
• Ad Relevance: 22%

Example:
If a keyword has

• Above-average CTR (3.9 points)
• Average ad relevance (2.2 points)
• Above-average landing page experience (3.9 points)
  → Total score: 1 (base) + 3.9 + 2.2 + 3.9 = 11 → rounded down to 10

That means focusing on CTR and landing page experience will often give you the highest return on optimization.

7 Proven Ways to Improve Your Google Ads Quality Score1. Use Long-Tail Keywords

Specific, intent-rich keywords improve CTR and ad relevance.
Example: Use “buy eco-friendly yoga mats USA” instead of “yoga mats.”

2. Match Ad Copy to Search Intent

Customize each ad group’s copy to match its keywords.
Include the keyword in headlines and descriptions.

3. Optimize Your Landing Pages

Your landing page should reflect your ad promise.
Ensure fast load speed, mobile responsiveness, and relevant content.

4. Add Negative Keywords

Prevent your ads from showing for irrelevant queries.
Check the Search Terms report weekly.

5. A/B Test Ads Regularly

Test variations of ad headlines and CTAs to improve engagement.

6. Use Ad Extensions

Sitelinks, callouts, and structured snippets enhance ad visibility and CTR.

7. Structure Campaigns Clearly

Group keywords by theme and ensure ad copy speaks directly to them.

Why Quality Score Helps Small Advertisers Compete

Quality Score isn’t just a tool for saving money—it’s a competitive equalizer.

If a smaller advertiser writes highly relevant ads and uses great landing pages, they can outperform bigger brands with higher budgets. That’s because Google prioritizes user experience—not just the size of your wallet.

How Quality Score Affects CPC and Ad Rank

Google calculates Ad Rank using this formula:

Ad Rank = Max CPC × Quality Score

If your competitor bids $4 with a Quality Score of 5, their Ad Rank is 20.
If you bid $2 with a Quality Score of 10, your Ad Rank is also 20.
But you pay less per click—and potentially rank higher.

That’s why improving your Quality Score is one of the best ways to stretch your budget without sacrificing performance.
