How Is Quality Score Calculated? The Complete Guide
Quality Score is Google’s rating of the quality and relevance of both your keywords and PPC ads. It’s used to determine your cost per click (CPC) and multiplied by your maximum bid to determine your ad rank in the ad auction process.
Understanding how Quality Score is calculated can help you optimize your Google Ads campaigns for better performance and lower costs. This comprehensive guide will explain everything you need to know about Quality Score calculation.
What Is Quality Score?
Quality Score is a diagnostic tool that gives you an idea of how well your ad quality compares to other advertisers. Scores range from 1 to 10, with 10 being the best possible score. Higher Quality Scores typically lead to lower costs and better ad positions.
The three main components that determine your Quality Score are:
- Expected click-through rate (CTR): The likelihood that your ad will be clicked when shown
- Ad relevance: How closely your ad matches the intent behind a user’s search
- Landing page experience: How relevant and useful your landing page is to people who click your ad
How Quality Score Is Calculated
While Google doesn’t reveal the exact algorithm for calculating Quality Score, we know it’s determined by both current and historical performance data. Here’s how each component contributes:
1. Expected Click-Through Rate (40% weight)
This is the most important factor in Quality Score calculation. Google estimates how likely your ad is to be clicked when shown for a particular keyword. This estimation is based on:
- Your ad’s historical CTR for that keyword
- The CTR of other advertisers showing ads for that keyword
- The position your ad appears in on the page
- Other format factors (like ad extensions)
Google compares your expected CTR to other advertisers and rates it as:
- Above average (top 33% of advertisers)
- Average (middle 33% of advertisers)
- Below average (bottom 33% of advertisers)
2. Ad Relevance (30% weight)
Ad relevance measures how closely your ad matches the intent behind a user’s search query. Google analyzes:
- The keywords in your ad groups
- The text in your ads
- The search queries that trigger your ads
- How well these elements align with each other
Like expected CTR, ad relevance is rated as above average, average, or below average compared to other advertisers.
3. Landing Page Experience (30% weight)
This measures how relevant, transparent, and easy-to-navigate your landing page is for people who click your ad. Google evaluates:
- Relevance of content to the ad and keyword
- Transparency about your business
- Ease of navigation
- Page load speed
- Mobile-friendliness
- Amount of original content
| Quality Score Component | Weight in Calculation | How to Improve |
|---|---|---|
| Expected CTR | 40% | Write compelling ad copy, use relevant keywords, improve ad positioning |
| Ad Relevance | 30% | Create tightly themed ad groups, match ad text to keywords, use dynamic keyword insertion |
| Landing Page Experience | 30% | Improve page speed, ensure content matches ad promise, make navigation intuitive, optimize for mobile |
Quality Score Thresholds and What They Mean
While Quality Scores range from 1 to 10, here’s generally what each range means for your account performance:
- 1-3: Poor – Your ads are rarely showing or are very expensive when they do
- 4-6: Average – Your ads are showing but could perform better
- 7-8: Good – Your ads are performing well with decent CTR and relevance
- 9-10: Excellent – Your ads are highly relevant with strong performance
| Quality Score | Classification | Estimated CPC Impact | Percentage of Advertisers |
|---|---|---|---|
| 1-3 | Poor | Up to 400% higher CPC | ~15% |
| 4-6 | Average | Neutral to 50% higher CPC | ~60% |
| 7-8 | Good | Up to 30% lower CPC | ~20% |
| 9-10 | Excellent | Up to 50% lower CPC | ~5% |
How Quality Score Affects Your Ad Rank and CPC
Quality Score directly impacts two crucial aspects of your PPC performance:
- Ad Rank: Determines your ad position on the search results page
- Actual CPC: Determines how much you actually pay for each click
The formula for Ad Rank is:
Ad Rank = Max CPC Bid × Quality Score
For Actual CPC, Google uses this formula:
Actual CPC = (Ad Rank of ad below you / Your Quality Score) + $0.01
This means that with a higher Quality Score:
- You can achieve higher ad positions with lower bids
- You’ll pay less per click than competitors with lower Quality Scores
- Your ads will show more frequently for the same budget
How to Improve Your Quality Score
Improving your Quality Score requires optimizing each of the three main components. Here are specific strategies for each:
1. Improving Expected CTR
- Write compelling ad copy: Highlight unique selling points and include strong calls-to-action
- Use ad extensions: Sitelinks, callouts, and structured snippets can improve CTR
- Test different ad variations: Try different headlines and descriptions to find what works best
- Improve ad positioning: Higher positions generally have better CTR
- Use negative keywords: Prevent your ads from showing for irrelevant searches
2. Improving Ad Relevance
- Create tightly themed ad groups: Group similar keywords together with highly relevant ads
- Use keyword insertion: Dynamically insert the search keyword into your ad text
- Match ad text to landing pages: Ensure your ad promises match what’s on the landing page
- Use all available ad text: Maximize character limits in headlines and descriptions
- Test different match types: Exact match often performs better for relevance
3. Improving Landing Page Experience
- Match content to ads: Deliver exactly what your ad promises
- Improve page speed: Use Google’s PageSpeed Insights to identify opportunities
- Make navigation intuitive: Help users find what they’re looking for quickly
- Optimize for mobile: Ensure your page works well on all devices
- Be transparent: Clearly display your business information and policies
- Reduce bounce rate: Keep visitors engaged with relevant content
Common Quality Score Myths Debunked
There are many misconceptions about Quality Score that can lead to poor optimization decisions. Let’s clarify some common myths:
- Myth: Quality Score is the most important metric in Google Ads.
Reality: While important, it’s just one of many metrics to consider. Don’t sacrifice conversions just to improve Quality Score. - Myth: You need a Quality Score of 10 to be successful.
Reality: A score of 7-8 is generally excellent. Focus on performance, not just the number. - Myth: Quality Score affects your actual CPC directly.

Reality: If those keywords are converting profitably, keep them. Quality Score isn’t everything. - Myth: Quality Score is calculated in real-time for each auction.
Reality: It’s updated periodically based on historical data, not in real-time.
