Google Ads Quality Score Explained: Everything You Need to Know
Quality Score is one of the most discussed and misunderstood metrics in Google Ads. Many advertisers obsess over getting a perfect 10/10 score, while others ignore it completely. The truth sits somewhere in the middle.
Understanding how Quality Score works can help you improve campaign performance, lower advertising costs, and create a better experience for potential customers. However, many outdated explanations of Quality Score no longer reflect how Google Ads operates today.
In this guide, we’ll break down exactly what Quality Score is, how it affects your campaigns, and what you should focus on to improve it effectively.
What Is Google Ads Quality Score?
Quality Score is a rating Google assigns to keywords within your Google Ads campaigns. It ranges from 1 to 10:
- 1 = Very poor
- 10 = Excellent
The score acts as an indicator of how relevant and useful Google believes your ads are to users searching for specific terms.
Google calculates Quality Score using three main factors:
- Expected click-through rate (CTR)
- Ad relevance
- Landing page experience
Together, these determine how effectively your ads match a user’s search intent and how likely users are to have a positive experience after clicking your ad.
The Three Factors That Influence Quality Score
1. Landing Page Experience
Landing page experience is often the most misunderstood element of Quality Score because Google describes it in fairly broad terms.
In simple terms, Google wants to know whether your website provides a good experience for users after they click your ad.
What Makes a Good Landing Page Experience?
Relevant and Useful Content
Your landing page should directly address the user’s search query.
For example:
- If someone searches for “emergency plumber in Manchester”, your page should specifically discuss emergency plumbing services in Manchester.
- Generic service pages with vague information tend to perform poorly.
Google also values:
- Unique content
- Helpful explanations
- Clear value propositions
- Information that genuinely assists the user
Duplicate content across multiple pages can negatively affect how Google evaluates your landing pages.
Easy Website Navigation
Users should be able to quickly find what they need.
Ask yourself:
- Can visitors locate important information within one click?
- Is the navigation menu clear?
- Are contact details easy to find?
- Can users easily move between related services?
A confusing website structure creates a poor landing page experience.
Mobile Optimisation
This is no longer optional.
If your website performs badly on mobile devices or tablets, your Quality Score will almost certainly suffer.
Your site should:
- Load quickly
- Display correctly on all screen sizes
- Be easy to navigate using touch controls
- Avoid intrusive pop-ups
In 2026, mobile usability is a fundamental requirement.
2. Expected Click-Through Rate (CTR)
Expected CTR measures how likely Google believes users are to click your ad when it appears.
A higher expected CTR usually indicates that your ad is appealing and relevant to searchers.
Google uses historical data to estimate this likelihood.
How to Improve Expected CTR
The most obvious tactic is including keywords in your ads. However, nearly every advertiser does this, so it’s rarely enough on its own.
To stand out, focus on:
- Strong unique selling points (USPs)
- Compelling offers
- Clear benefits
- Emotional triggers
- Strong calls to action
Examples include:
- Free delivery
- Same-day service
- 24/7 support
- Price guarantees
- Exclusive discounts
The goal is to make users choose your ad over competitors.
3. Ad Relevance
Ad relevance measures how closely your ad matches the user’s search intent.
Google wants your ad copy to align naturally with the keywords triggering the ad.
Responsive Search Ads and Relevance
Google Ads now provides direct feedback inside Responsive Search Ads by highlighting whether your keywords appear in headlines and descriptions.
This helps advertisers ensure:
- Keywords are properly integrated
- Ads remain tightly themed
- Messaging matches search intent
However, keyword inclusion alone is not enough.
The Importance of Copywriting
Strong copywriting is now a major differentiator.
Because everyone is targeting similar keywords, advertisers must focus on:
- Persuasive wording
- Clear messaging
- Concise communication
- Strong value propositions
Writing effective ads with limited character counts is a specialised skill that can dramatically influence performance.
How Long Does It Take to Improve Quality Score?
One of the most common questions advertisers ask is:
“How quickly will my Quality Score improve after optimisation?”
Unfortunately, there is no fixed answer.
Sometimes Improvements Happen Quickly
In poorly optimised campaigns, major improvements can happen within 24 hours after:
- Fixing landing pages
- Improving ad relevance
- Updating outdated ad formats
- Enhancing website usability
Sometimes It Takes Much Longer
In other cases, improvements happen slowly because Google needs enough data to evaluate performance changes.
For example:
- Keywords generating only a few clicks per day may take weeks to update
- High-volume keywords can update much faster
The more data Google collects, the quicker it can reassess Quality Score.
A Useful Trick for Landing Page Re-Evaluation
Sometimes advertisers improve landing pages significantly but notice no Quality Score change.
One workaround that occasionally helps is:
- Creating a new URL version of the improved landing page
- Updating the ad with the new URL
This can trigger Google to re-evaluate the page from scratch.
However, there are important SEO considerations.
If you duplicate content:
- Use noindex directives on PPC landing pages
- Avoid creating duplicate content issues for organic SEO
Is There a Hidden Account-Level Quality Score?
Google officially states that Quality Score exists at the keyword level only.
However, many PPC professionals believe Google may also evaluate:
- Account-wide performance
- Historical optimisation quality
- Overall advertiser trust
Google has never confirmed this.
Still, the theory makes logical sense.
If one advertiser consistently creates:
- High-performing campaigns
- Relevant ads
- Strong landing pages
…it would not be surprising if Google rewarded that advertiser more favourably when launching new campaigns.
Conversely, poorly managed accounts may struggle to gain momentum.
Although unconfirmed, many advertisers believe account history influences performance indirectly.
Should You Pause Keywords with Low Quality Scores?
Some advertisers wonder whether they should pause low-scoring keywords to improve their average Quality Score.
In most cases, the answer is no.
Why Removing Keywords Can Hurt Performance
Even low Quality Score keywords can still generate conversions.
For example:
- A keyword with a low score may only convert once every 30–60 days
- But that conversion could still be valuable
Removing keywords purely to improve averages can reduce opportunities unnecessarily.
What You Should Do Instead
Focus on optimisation:
- Improve landing pages
- Enhance ad relevance
- Strengthen ad copy
- Increase CTR
Improving keyword performance is far more valuable than artificially manipulating averages.
Why Quality Score Still Matters
Historically, Quality Score played a direct role in Google’s Ad Rank formula:
Max CPC Bid × Quality Score = Ad Rank
This meant higher Quality Scores could significantly reduce advertising costs while improving positioning.
But Google Ads Has Changed
Modern Google Ads uses a far more advanced system involving:
- Automated bidding
- Auction-time signals
- User context
- Device behaviour
- Location
- Intent signals
- Historical performance
Today, Google uses multiple factors to determine Ad Rank.
As a result, Quality Score is now more of a reflection of performance quality rather than the sole driver of ad positioning.
How to Interpret Your Quality Score
Rather than obsessing over achieving a perfect 10/10, think of Quality Score in performance ranges.
Quality Score 8–10
This generally means:
- Your ads are highly relevant
- Your landing pages are strong
- Google sees your campaigns positively
At this level, improving from 8 to 10 usually provides limited practical benefit.
You’re often better off focusing on:
- Conversion rate optimisation
- Bid strategies
- Audience targeting
- Scaling campaigns
Quality Score 5–7
This suggests moderate relevance.
You likely need to improve:
- Ad copy
- Landing page quality
- CTR
- Keyword alignment
There is room for meaningful optimisation here.
Quality Score 1–4
This indicates serious relevance or usability issues.
Google likely views your campaigns as:
- Poorly targeted
- Unhelpful
- Low quality
At this level, you may experience:
- Higher CPCs
- Lower ad visibility
- Poor overall performance
Significant optimisation work is usually required.
Final Thoughts
Quality Score remains an important metric in Google Ads, but not for the reasons many advertisers believe.
It is no longer simply a mathematical multiplier determining ad position. Instead, it acts as a performance indicator showing how Google evaluates your campaigns overall.
The key areas to focus on are:
- Relevant ads
- Strong copywriting
- High CTRs
- Excellent landing page experiences
- Mobile-friendly websites
- Helpful and unique content
Most importantly, don’t obsess over perfection.
If your campaigns consistently achieve Quality Scores between 8 and 10, your time is often better spent improving broader business metrics such as conversion rates, lead quality, and profitability rather than chasing marginal Quality Score gains.
