What Is Google Ads Quality Score?

It's 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 an advertiser for each click.

But really...

It compares competing ads across different user experience metrics for a specific ad auction, then rewards advertisers that provide a better user experience while punishing those that don't.


Why does Quality score MATTER?

Reason #1

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

CPC = a QS ❏ Expand
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).

Reason #2

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

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.

Differences between Ad Rank and Quality Score

Although both concepts might appear similar on-page, in reality, they are not.

Quality Score is a parameter provided by Google that allows advertisers to monitor the quality of their ads. Google calculates Quality Scores using CTR, Ad Relevance, Landing Page Experience and other factors. Advertisers use the score to determine whether or not their campaign needs optimization.

Ad Rank, on the other hand, is not provided by Google but is a hidden value that their algorithm uses to rank the ads on search results. The ad with the higher Ad Rank gets the first position, and so forth.

From the formula above, it can be seen that Ad Rank and Quality Score are directly correlated. A higher Quality Score can increase your Ad Rank and reduce your ad costs.

Apart from the quality score, there are other factors that influence Ad Rank. Additional factors include your bid amount, ad quality (CTR, Ad Relevance and Landing Page Experience), Ad Rank thresholds, auction competitiveness, the context of search, nature of search term, etc. You can check out all the factors shared by Google itself here.

Hence, we can see that Ad Rank does take into account the factors from which Quality Score is calculated but there are other factors too that Google uses to rank and display the ads to the users which not only depends upon the ad quality but also on the searcher's context (location, query, other user signals and attributes).


Where to find Quality Score in Google Ads

In campaigns that are targeted on Google Search, each keyword has a Quality Score. But it is hidden by default. Here's how to add quality scores column 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.



In theory, the main factors that go into the calculation of Quality Score are:

  1. Expected Clickthrough Rate (CTR)
  2. Ad Relevance
  3. 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's a better way to think about Quality Score factors towards optimizing it effectively.


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 pages must be related to each other.

Landing page relevance
Landing Page Experience

Your landing pages should provide a good user experience by providing what was promised in the ad, by making it easy to find out more about your business and by being explicit about how their information is used.

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.

A 7/10 Quality Score is the recommended number and can be considered 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.

  • 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. By achieving this high quality score, 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.

How To Improve Quality Score

First, in every single case, getting a near 10/10 Quality Score happens when your ad click-through-rate (CTR) is much higher than all advertisers competing in your ad auctions. 2X or 3X higher. In thriving to get a 10/10, you might reach a 7/10, and decide it's good enough. Here are the most important steps to follow:
  1. Structure your ad groups by intent.

    The best ad in the world will fail if it's not talking to the right person. The message you write needs the right foundation: ad groups that are structured in families of search intent, where each keyword shares the same intent as it's neighbors. Tenscores' keyword grouping tool does this automatically and it increases the Ad Relevance factor.
  2. Get a better click-through-rate (CTR) than your competitors

    When structure is right, focus the rest of your time on testing new ads, relentlessly. Test one new ad every 200-500 impressions. You wan't to double or triple your ad CTR. Do this until your Expected CTR is above average.
  3. Use CTR to improve Landing Page Experience.

    What you learn when testing your ads will tell you what to put on your landing pages for a seemless user experience. The ad you write that gets the best attention is only a summary of what the user wants to see on your landing page. You will find that this also improves conversion rates.
It's not that hard if you follow that advice, and most importantly if you improve your ad writing skills. It is not easy to get there, but on that journey, you will learn a lot about the people you're trying to reach in ways that will improve your entire conversion funnel.

How do I start with good Quality Scores?

The keywords you choose are the first step to getting a higher Quality Score. On the spectrum of keyword research, you will find that your brand terms will often have a Quality Score from the start. It's because they are highly relevant: someone is searching for your company, they find it, they stick around. On the other end of the spectrum, you will find that bidding on your competitor terms will have poor Quality Score. It's because your own company is less relevant when someone is searching for your competitors: they will ignore you, most of the time. In knowledge of that, it is best to start advertising on your brand terms first, then work your way down the spectrum figuring out how to serve the searcher at each step and building a history of quality advertising that Google will reward you for.

What about display network quality score (content network quality score)?
