How Quality Score Impacts Your Ad Campaigns & How to Improve It

By Sunil Kumar

Quality Score is a metric used by Google Ads to measure the quality and relevance of an advertiser’s ads and keywords. It is a score ranging from 1 to 10 that indicates how well an ad is likely to perform based on factors such as click-through rate (CTR), ad relevance, and landing page experience.

Why Is Quality Score Important?

Quality Score is important because it directly affects the cost and effectiveness of your ad campaigns. A high-Quality Score can lead to lower costs per click, higher ad rankings, and more impressions. On the other hand, a low-Quality Score can result in higher costs per click, lower ad rankings, and fewer impressions.

How Does Quality Score Impact Ad Campaigns?

The impact of Quality Scores on ad campaigns cannot be overstated. A high-Quality Score can lead to better ad positioning, higher click-through rates, and lower cost per click, resulting in a better return on investment (ROI) for the advertiser. On the other hand, a low-Quality Score can result in lower ad positioning, higher costs per click, and poor ad performance, leading to a lower ROI. Therefore, optimizing for Quality Scores is a key strategy for successful ad campaigns.

What Are the Components of a Quality Score?

The Quality Score is determined by three main components:

  1. Click-through rate (CTR): CTR is the percentage of people who click on your ad after seeing it. A higher CTR indicates that your ad is more relevant and engaging to your target audience.
  2. Ad relevance: Ad relevance refers to how well your ad matches the user’s search intent. A highly relevant ad will have a higher chance of attracting clicks and conversions.
  3. Landing page experience: The landing page experience refers to the relevance, usability, and quality of the page that the user lands on after clicking on your ad. A positive landing page experience can lead to higher conversions and a better user experience.

How Google Calculates Quality Score?

Google calculates Quality Score based on several factors, including the relevance and quality of your ad campaign, the historical performance of your keywords, and the landing page experience. Google uses machine learning algorithms to analyze these factors and determine the Quality Score of your ad campaign.

The exact formula used is not disclosed by Google, but it is known that each component is given a weight based on its importance.

Why does Quality Score Differ Between Search Engines?

Quality Scores can differ between search engines because each search engine has its own algorithm for determining ad relevance and quality. 

For example, Bing and Yahoo use their own algorithms to calculate Quality Scores, which may differ from Google’s algorithm. Additionally, different search engines may place varying levels of importance on different factors when calculating Quality Scores.

What Are the Benefits of a High-Quality Score?

  1. Lower costs per click: A high-Quality Score can result in lower costs per click as search engines reward advertisers who provide relevant and high-quality ads with lower costs.
  2. Higher ad rankings: A high-Quality Score can improve your ad’s position on the search engine results page, leading to increased visibility and clicks.
  3. More impressions: A high-Quality Score can lead to more impressions, as your ad is more likely to be shown to potential customers.

Consequences of a low-Quality Score:

  1. Higher costs per click: A low-Quality Score can result in higher costs per click as search engines may charge you more for displaying less relevant ads.
  2. Lower ad rankings: A low-Quality Score can result in lower ad rankings, leading to fewer clicks and lower visibility.
  3. Fewer impressions: A low-Quality Score can result in fewer impressions, as search engines may show your ad to fewer potential customers.

Quality Score is one of the main factors that search engines use to determine ad rank and cost per click. A higher Quality Score can lead to a higher ad rank and lower costs per click, while a lower Quality Score can result in a lower ad rank and higher costs per click.

How to Improve Quality Score for Better Ad Positioning?

Improving the Quality Score is an important part of optimizing ad campaigns in Google Ads. Here are some key tactics for improving Quality Scores:

  1. Conducting keyword research: Thorough keyword research helps to identify the most relevant and high-performing keywords for your ad campaigns. This ensures that your ads are targeting the right audience and appearing in front of users who are most likely to be interested in your products or services.
  2. Creating relevant ad groups: Organizing your ad groups into tightly themed clusters of keywords ensures that your ads are highly relevant to users’ search queries, which can improve click-through rates and ad performance.
  3. Writing compelling ad copy: Writing compelling ad copy that aligns with users’ search intent and highlights the unique value proposition of your product or service can help to increase click-through rates and improve ad relevance.
  4. Optimizing landing pages: A high-quality landing page that is relevant to the ad and provides a seamless user experience can improve the landing page experience, which is a key component of the Quality Score.
  5. Testing and refining ads: Regularly testing and refining ad copy, targeting, and landing pages can help to identify the most effective tactics for improving Quality Score and achieving optimal ad performance.
  6. Monitoring and adjusting campaigns: Continuously monitoring campaign performance and making adjustments to improve ad relevance, click-through rates, and landing page experience is essential for maintaining a high-Quality Score and achieving long-term success in Google Ads.

What Are the Common Mistakes That Negatively Impact Quality Scores?

  1. Poorly targeted keywords: Choosing irrelevant or broad keywords can negatively impact Quality Score. Instead, focus on targeting keywords that are specific to your product or service.
  2. Lack of ad relevance: Ads that do not align with the search intent of users can lead to a lower Quality Score. Ensure that your ad copy and landing pages are relevant to the user’s search query.
  3. Poor landing page experience: A low-quality landing page that does not provide relevant information or a good user experience can negatively impact Quality Score.
  4. Low click-through rates (CTR): Low CTR indicates that your ads are not relevant or engaging to users, which can lead to a lower Quality Score.
  5. Poor budget: Not allocating enough budget to your ad campaigns can result in low ad positions and low-Quality Scores.

How to Avoid These Mistakes:

  1. Conduct thorough keyword research to identify the most relevant and high-performing keywords for your ad campaigns.
  2. Organize your ad groups into tightly themed clusters of keywords to improve ad relevance.
  3. Ensure that your ad copy and landing pages align with users’ search intent and provide relevant information.
  4. Improve the landing page experience by ensuring that your pages load quickly, are mobile-friendly, and provide a clear call-to-action.
  5. Monitor and adjust your ad campaigns regularly to improve click-through rates and maintain a high-Quality Score.
  6. Ensure that you have allocated an adequate budget to your ad campaigns to achieve optimal ad positioning and maintain a high-Quality Score.


Quality Score is a critical factor in the success of any Google Ads campaign. A high-Quality Score can lead to better ad positions, lower costs per click, and ultimately, more conversions. It is essential to focus on improving the Quality Score by optimizing ad relevance, click-through rate, and landing page experience. 

To achieve success in Google Ads, it is essential to prioritize Quality Score optimization. By regularly monitoring and refining ad campaigns and avoiding common mistakes that can negatively impact Quality scores, advertisers can reach their target audience more effectively and achieve their desired campaign goals.
