What's an Ad Quality Score?
Running Google Ads isn't just about bidding more than your competitors. In fact, throwing more money at your campaigns isn't always the answer. Google also looks at how relevant and useful your ads are to the people searching, and that's where your ad quality score comes in.
If you've ever wondered what an ad quality score is, why it matters, or how to improve it, you're in the right place. In this guide, we'll break it all down in plain English so you can build better campaigns, improve your results, and get more value from your advertising budget.
Key Takeaways
An ad quality score is Google's 1–10 rating of how relevant and useful your ads are.
Google evaluates expected click-through rate, ad relevance, and landing page experience.
A higher Google ad quality score can help improve visibility while lowering advertising costs.
Quality Score is a diagnostic tool, not a performance metric.
Improving your users' experience is the best way to improve your score over time.
What's an Ad Quality Score?
An ad quality score is Google's rating of how relevant and useful your search ads, keywords, and landing pages are for someone searching on Google.
Quality Score is measured on a scale from 1 to 10, with 10 being the highest. Google assigns this score at the keyword level, giving advertisers insight into how well their ads match what users are looking for.
Think of it like a report card.
Google isn't grading how much money you're spending. Instead, it's grading how well you're serving your audience.
A high score generally means your ads closely match the searcher's intent and provide a positive experience after someone clicks. A lower score usually indicates opportunities to improve your ads, keywords, or landing pages.
One important thing to remember is that Quality Score is a diagnostic tool, not a goal in itself. Google specifically recommends using it to identify areas for improvement rather than treating it like a key performance indicator.
Why Does Google Use an Ad Quality Score?
Google's entire business depends on delivering relevant search results. They want you to come to their search engine, ask your question, and find the answer faster than any other search engine.
If users constantly clicked on ads that didn't answer their questions, they'd lose trust in Google. That's why Google rewards advertisers who create helpful, relevant experiences.
The better your ads serve users, the better they often perform.
Google uses ad quality score to encourage advertisers to:
Create ads that match search intent
Send visitors to useful landing pages
Improve the overall search experience
Reduce irrelevant or misleading advertising
When everyone creates better ads, everyone wins. Users find what they're looking for faster, advertisers receive more qualified traffic, and Google continues providing a search experience people trust.
How Does Google Calculate Ad Quality Score?
Your Google ad quality score is based on three primary factors.
1. Expected Click-Through Rate (CTR)
Expected click-through rate is Google's prediction of how likely someone is to click your ad when it's shown.
It's based on historical performance and other signals, not simply how your ad performs today.
Google looks at questions like:
Does your headline grab attention?
Does your offer match what someone searched?
Have similar ads historically earned clicks?
If your expected CTR is below average, consider:
Writing stronger headlines
Highlighting unique benefits
Including a clear call to action
Matching your ad copy to the keyword
The goal isn't simply more clicks. It's attracting the right clicks.
2. Ad Relevance
Ad relevance measures how closely your ad matches the keyword and the searcher's intent.
Imagine someone searches:
"Emergency roof repair."
An ad that simply says:
"We do roofing."
is far less relevant than one that says:
"Emergency Roof Repair Available Today | Free Inspection | Licensed Roofing Experts."
The closer your messaging matches the search, the better your ad relevance tends to be.
One of the easiest ways to improve this is to organize your campaigns into tightly themed ad groups rather than placing dozens of unrelated keywords in a single group.
3. Landing Page Experience
Getting someone to click your ad is only half the battle.
Once they arrive, your landing page needs to deliver exactly what your ad promised.
Google looks at factors like:
Does the page answer the user's question?
Is it easy to navigate?
Does it load quickly?
Is it mobile-friendly?
Is the information trustworthy and useful?
For example, if your ad promotes "custom kitchen remodeling," visitors shouldn't land on your homepage and be forced to search for that information themselves.
Instead, they should land on a page dedicated to your kitchen remodeling services.
Is Quality Score the Same as Ad Rank?
This is one of the biggest misconceptions about Google Ads.
No, they're not the same thing.
Quality Score is simply a diagnostic tool that helps you understand where improvements can be made.
Ad Rank, on the other hand, determines where your ad actually appears in Google's search results.
While ad quality influences Ad Rank, Google also considers factors like:
Your bid amount
Auction-time signals
Competition
Ad assets
Search context
Device
User location
That's why improving your Quality Score can help your campaigns, but it isn't the only factor determining success.
Why Does Your Google Ad Quality Score Matter?
Although it isn't a KPI, Quality Score can significantly impact your campaigns.
Better Ad Placement
Relevant ads are more likely to appear in stronger positions because Google wants users to see helpful results first.
Lower Cost Per Click
Higher-quality ads often require less money to compete for the same keywords.
That doesn't mean you'll always pay less, but improving relevance can make your advertising budget work harder.
Better Return on Investment
When your ads closely match user intent, you're more likely to attract qualified visitors who actually want your products or services.
That often leads to better conversion rates, not just more traffic.
Better User Experience
Ultimately, Google rewards advertisers who make life easier for searchers. The better experience you create, the stronger your campaigns typically become.
How to Improve Ad Quality Score
Improving your ad quality score isn't about gaming Google's system. It's about creating a better experience for your audience.
Group Similar Keywords Together
Avoid placing dozens of unrelated keywords into a single ad group.
Instead, organize keywords into tightly related themes so you can write ads that specifically match each search.
Write Better Ads
This seems obvious, but it’s important to understand. Your ads should feel like a natural answer to the user's question.
Use your keywords naturally while highlighting the benefits of your product or service, any of the unique selling points that make you stand out against the competition. Include calls to action, like buy now, or schedule today.
Be sure to also regularly update and include any relevant offers. If you have a sale, let people know so they come to your site.
The more closely your ad matches search intent, the more likely people are to engage.
Improve Your Landing Pages
Your landing page should continue the conversation your ad started.
Ask yourself:
Does this page answer the visitor's question?
Is it fast?
Does it work well on mobile?
Is there a clear next step?
Is the content trustworthy?
A great landing page isn’t just about increasing the Quality Score. You need a landing page that drives people to take your desired conversion action. Make sure the page you’re taking them to does that.
Remove Irrelevant Traffic
Not every search is worth paying for, and that’s okay!
Using negative keywords helps prevent your ads from appearing for searches that aren't a good fit, improving both relevance and efficiency.
Review Performance Regularly
Google Ads isn't a "set it and forget it" platform. Our ad specialist is inside the account every single day, making minor adjustments to make sure we’re always operating at a high level.
Regularly review:
Click-through rate
Conversion rate
Landing page performance
Keyword relevance
Quality Score trends
Small improvements over time often produce the biggest long-term gains.
Common Ad Quality Score Mistakes
Even experienced advertisers make these mistakes.
Mistake #1: Chasing the Score
A Quality Score of 10 doesn't automatically mean your campaign is successful.
Your goal is profitable leads and sales, not a perfect score.
Mistake #2: Sending Every Ad to Your Homepage
Your homepage rarely answers every searcher's question.
Whenever possible, send visitors directly to the most relevant page.
Mistake #3: Using Generic Ads
One ad shouldn't try to serve dozens of unrelated searches.
Specific ads almost always outperform generic ones.
Mistake #4: Ignoring Landing Page Experience
Even an excellent ad can struggle if the landing page is slow, confusing, or unrelated.
Think of your landing page as part of your ad, not an afterthought.
Mistake #5: Focusing Only on Clicks
A high click-through rate doesn't always equal success.
Sometimes slightly fewer clicks produce far better leads.
The goal is to attract qualified visitors, not simply generate traffic.
Quality Score vs. Campaign Performance
This is worth repeating because it's so important.
A campaign with a Quality Score of 6 can outperform a campaign with a score of 9 if it generates more qualified leads, has lower acquisition costs, and drives higher revenue.
That's because Quality Score isn't designed to measure business success.
It's designed to help identify opportunities to improve user experience.
At New Hill Marketing, we don't chase perfect scores.
We focus on building campaigns that generate real business results. If improving your Quality Score helps accomplish that goal, great. But conversions, leads, and revenue will always matter more than a number inside Google Ads.
What's an Ad Quality Score Really About?
At the end of the day, your ad quality score is really about one thing: creating a better experience for your audience.
When your keywords match your ads, your ads match your landing pages, and your landing pages genuinely help visitors, Google notices.
The result is often stronger visibility, lower costs, and more qualified traffic, but more importantly, it's a better experience for the people you're trying to reach.
Focus on helping your audience first, and your Quality Score will usually improve.
