The Google Ads quality score is an indicator that measures the quality of your ads and keywords on a 1-10 scale; raising it both lowers cost and improves ad position. Below you will find the three components of the score, why it is important, and concrete ways to improve each component.
What Is the Quality Score, Which 3 Components Make It Up?
The Quality Score is an indicator with which Google Ads rates the quality and relevance of your ads and keywords between 1 and 10; 10 is the best. It is shown at the keyword level and rests on three main components.
The components are as follows: expected click-through rate (the likelihood of your ad being clicked when shown), ad relevance (how well your ad text matches the searched word) and landing page experience (how relevant, useful and fast the page the clicker reaches is). Google rates these three as "above average", "average" or "below average". In essence, the quality score is Google's grade for the question "how good an experience does this ad offer the user"; you can also see its definition in Google's help docs.
Why Is the Quality Score Important? (Cost and Ranking)
The quality score is important because it directly affects your ad cost and visibility. Google decides which ad shows in which position with the Ad Rank, and in this ranking, alongside your bid, the quality score plays a big role.
The practical results are clear: a high quality score lets you pay a lower cost per click (CPC) for the same position, increases your ad's chance of showing in higher positions, and raises your return on investment. While managing Google Ads, I have repeatedly seen accounts with a low quality score pay many times more for the same click. Conversely, a low score means paying more for the same position and spending the budget inefficiently. I covered the cost side in detail in my CPC article.
1. Improve the Expected Click-Through Rate (CTR)
The expected click-through rate expresses the likelihood of your ad being clicked; to raise it you need to make the ad more appealing and relevant for the user:
- Attention-grabbing headlines: write headlines that offer what the user searches and a clear benefit; put the keyword in the headline.
- Clear call to action: add a CTA like "Discover now", "Try for free".
- Distinguishing feature: highlight what sets you apart, like a price advantage, campaign, free shipping or guarantee.
- Ad extensions: extensions like sitelinks, descriptions and phone enlarge the ad and increase clicks.
- A/B testing: try different headline and text variations and find the one clicked most.
A high click-through rate both feeds the quality score and lets you use your budget more efficiently with relevant traffic. A well-written and relevant ad text is the key to this component.
2. Increase Ad Relevance
Ad relevance measures how well your ad text matches the keyword the user searches; the way to raise it is a tight "keyword, ad, intent" match. If the term the user searches appears in the ad headline or text, Google and the user find the ad more relevant.
Keep ad groups narrow and focused: instead of stuffing a group with dozens of unrelated words, group similar and close-meaning words; so you can write an ad specific to each group that speaks exactly to that word. Match the search intent (is the user looking to buy, or for information), avoid very general words, and weed out irrelevant words. The basic logic: every ad should make the search it shows on say "this is exactly what I was looking for, here is the answer".
3. Improve the Landing Page Experience
The landing page experience measures the quality of the page the user reaches after clicking the ad and is among the most neglected yet most important components of the quality score; you can find the criteria in Google's landing page guide.
The page must directly meet what the ad promised and what the user searched; direct the visitor not to an irrelevant homepage but to the exact relevant content. The page must load fast and work flawlessly on mobile, because most traffic is mobile. The content must be clear, the user must immediately understand what to do (buy, fill a form, call); a clean design, a prominent action button and trust-building information increase conversion. A good landing page raises both the quality score and the conversion rate; I listed the rules in my conversion-focused landing page article. The ad brings the user to the door, the landing page keeps them inside.
Account Structure, Negative Keywords and Extensions
Three structural elements support the quality score indirectly but strongly. Building the account and campaign structure tidily and on a narrow theme (each group focused on a single topic) lets you write a specific and relevant ad for each group; a messy structure lowers the score.
Negative keywords block the searches on which you do not want your ad to show (irrelevant words that bring no conversion); for example if you sell a paid product, you can add the words "free" and "no cost" as negatives. Ad extensions (sitelinks, descriptions, phone, location) enlarge the ad and offer more click area. Reviewing the three elements regularly, especially looking at the search terms report and adding new negatives, is the basic maintenance work for keeping the score sustainably high; I explained campaign setup step by step in my Google Ads guide.
Are the Quality Score and Optimization Score the Same Thing?
No, the two are different things and are often confused. The quality score is at the keyword level, given between 1-10, and is a measure of your ad and keyword quality (click rate, relevance, landing page); it mainly affects cost and ranking.
The optimization score, on the other hand, is at the account level, shown between 0-100 percent, and is an indicator that estimates how well your account is set up. Google offers you recommendations alongside this score (like bid adjustment, new keyword, adding an ad); applying the recommendations or dismissing them if unsuitable raises the score. The difference in short: the quality score answers "how good are your ads", the optimization score answers "how well is your account structured as recommended". An important note: do not blindly apply the optimization score recommendations, because every recommendation may not fit your goal; pick the sensible ones. I covered lowering cost in my Google Ads optimization article.
