What Is Google Ads Quality Score?

A grading system used by Google to decide whether an ad is good enough to be shown in the sponsored space of the search results, at what position it will be shown and how much to charge for each click.

Your ad's cost-per-click (CPC) depends on it, as shown in the formula:

This formula was revelead by Google in 2009. Today, we do not know everything that goes into the number a, but we can assume that whatever goes into it is divided by Quality Score, which results in wide differences in costs as shown below:
Here are the Quality Score penalties and discounts, and how they translate into percentage increases or decreases in cost-per-click (CPC).

Your ad's position (AdRank) on Google's search results depends on Quality Score. The higher the AdRank, the better the position. The first ad on Google is always the one that has the highest AdRank.

This formula was also revelead by Google in 2009. Today, we do not know everything that goes into the number b, but we can assume that whatever goes into it is multiplied by Quality Score.
Below is a real world example of the cost-per-click at each quality score of one advertiser. Join Tenscores to see this data for your own Google Ads account.

HOW TO See Quality Score?

In campaigns that are targeted on Google Search, each keyword has a Quality Score. But it is hidden by default. Here's how to show it in your Google Ads account:

  1. Click the "Keywords" tab..
  2. Click "Columns" then "Modify columns".
  3. Choose "Quality Score" in this new section.
  4. Select "Quality Score" in the list of options.
  5. Click "Apply" to save.

You should now have a Quality Score column in your data as shown below.



The official factors are: Expected Clickthrough Rate, Ad Relevance and Landing Page Experience.

That is a simplifed view of quality score components and they can be seen in your Google Ads account.

In practice, there are more factors.


The base
User Experience

"Relevance" and "Landing Page Experience" can be combined under the umbrella of User Experience. They simply mean that the user finds what was promised in the ad, and that they have a good experience when they reach your website.


Keywords, ads and landing page must be related to each other. Absolutely.

Landing page relevance
LP Experience

Your landing page should provide a good user experience. Not great, but good enough.

The Boost

Historical click-through-rates have an overwhelming impact on Quality Score. Users vote on the quality of your ads with their clicks. If you have a proven history of getting better CTR than others in your market, you get the best score.

  • Geo History

When there's no history in your account, Google will use other advertisers' historical performance on specific keywords to evaluate what Quality Score you should be granted. It is up to you to exceed performance.

A 7/10 Quality Score is the recommended number and is sufficient. Going above 7 is great but not always achievable and may not be worth the effort. Anything below 7 is a sign that something is wrong and should be worked on.

  • 10
  • Dead If you get a 1/10, you're in trouble. Google has or is about to ban your website. You'll hardly get any traffic and your costs will be exorbitant.
  • Sick At 2/10 and 3/10, your keywords are suffering. You're not getting all the traffic you could and you'll be charged very high prices for such bad scores. To go from 2 or 3 to 7/10 will require quite some expertise.
  • Weak These keywords need your attention and getting them above 7 should be accomplished without much trouble. Simply follow the flow chart at the bottom of this page. You'll most likely need to regroup your ad groups and write better ads.
  • Good You've accomplished what you needed in terms of quality. Google likes what you're doing in comparison to other advertisers and you're not being penalized in terms of traffic or costs.
  • Excellent The holy grail. At this point, you've surpassed Google's expectations and your performance is above average compared to other advertisers. Your costs are being discounted and your ads are appearing in prominent positions and more frequently.
  • The jump from 7/10 to anything above is not linear and sometimes doesn't make sense. Keywords often go from 7/10 immediately to 10/10 with no transition to 8 and 9.


You're in the right place, and just getting started. First, in every single case, getting a 10/10 Quality Score happens when your ad click-through-rate (CTR) is much higher than all other advertisers competing in your ad auctions. 2X or 3X higher. That's what you want to acheive. It is not easy to get there, but on that journey, you will learn a lot about the people you're trying to reach. Start by following the flowchart below.

How to improve Google Adwords Quality Score?

It's on every PPC practitioner's mind. First make sure that you meet all the requirements: decent landing page with privacy policy and keywords that are grouped in tight themes relating to a particular intent for a particular ad (Tenscores can do this automatically for you). Then second, focus 100% of your time on testing new ads for your top 3 keywords. Do this until their Quality Scores are above 7/10, then move on to next top 3 keywords. If you have low performing keywords in terms of CTR, pause them for a while. If you can advertise on high performing keywords like your brand terms or highly specific keywords for your niche, start with those and use them to build a good history of high CTR. It's not that hard if you follow that advice, and most importantly if you improve your ad writing skills.
