Google Ads Quality Score: How to Improve It and Lower Your CPC

What Is Google Ads Quality Score and Why Does It Matter?

⠀

Google Ads Quality Score is a diagnostic metric that rates the relevance and quality of your keywords, ads, and landing pages on a scale of 1 to 10. It is one of the most misunderstood numbers in paid search, yet it directly shapes how much you pay for each click and where your ads appear on the page.

Google calculates Quality Score using three core components: expected click-through rate (CTR), ad relevance, and landing page experience. Each component receives a rating of Below Average, Average, or Above Average. Together, they produce the final 1–10 score you see in your account.

Why should you care? Because Quality Score is a key input in the Ad Rank formula. Higher Ad Rank means better positions at lower costs. Two advertisers bidding the same amount for a keyword can see wildly different costs-per-click if one has a Quality Score of 8 and the other has a 4. The advertiser with the higher score pays less for better placement — a significant competitive advantage.

How Google Calculates Each Component ve Google Ads Quality Score

⠀

Understanding the three sub-components gives you a clear roadmap for improvement.

Expected Click-Through Rate

⠀

This predicts how likely your ad is to be clicked when it appears for a given keyword. Google compares your historical CTR to other advertisers competing on the same keyword, adjusting for ad position. A high expected CTR signals that your ad is compelling and relevant to searchers.

Ad Relevance

⠀

This measures how closely your ad copy matches the intent of the keyword being searched. If someone searches "running shoes for flat feet" and your ad talks generically about athletic footwear, your ad relevance will suffer. Tight thematic alignment between keyword and ad copy is essential.

Landing Page Experience

⠀

Google evaluates the page users land on after clicking your ad. It looks at whether the page content is relevant to the keyword, how fast the page loads, whether it is mobile-friendly, and whether it makes it easy for visitors to find what they are looking for. A poor landing page experience drags down your score even if your ad copy is excellent.

Five Proven Tactics to Improve Your Quality Score

⠀

Improving your google ads quality score is not a one-day project, but these five tactics produce consistent results.

1. Restructure into tightly themed ad groups. One of the most effective changes you can make is moving away from broad ad groups with dozens of keywords. Instead, group keywords into tight themes — sometimes called Single Keyword Ad Groups (SKAGs) or close variants thereof. When every keyword in a group shares the same core meaning, your ad copy can match it precisely, lifting both ad relevance and expected CTR.

2. Write ads that mirror the search query. Use Dynamic Keyword Insertion sparingly, but make sure your headline 1 contains the keyword the ad group targets. Address the exact problem the searcher has. If your keyword is "emergency plumber London," your headline should say "Emergency Plumber London — 24/7 Fast Response." Generic headlines hurt ad relevance scores.

3. Optimize for mobile landing page speed. Google's landing page experience component weighs mobile performance heavily. Use Google PageSpeed Insights to identify issues and aim for a Largest Contentful Paint (LCP) under 2.5 seconds. Compress images, eliminate render-blocking scripts, and use a reliable CDN.

4. Align landing page content with keyword intent. Your landing page must deliver exactly what the ad promised. If you advertise "free SEO audit," the landing page must feature that audit form above the fold — not a generic homepage. Map each ad group to a specific, purpose-built landing page.

5. Eliminate low-CTR keywords. Keywords with consistently poor CTR drag down your account's historical performance signals. Pause or delete keywords sitting at a CTR below 0.5% for more than a few hundred impressions. This keeps your account's relevance signals clean.

Understanding Quality Score at the Account Level

⠀

Many advertisers focus exclusively on keyword-level Quality Scores, but account-level health matters too. Google looks at your overall account history — your CTR across all keywords, your ad disapproval rate, and your conversion data — when assessing new keywords and campaigns.

This means that cleaning up old, underperforming campaigns has positive ripple effects. Removing keywords that haven't received clicks in six months, pausing campaigns with CTRs below 1%, and ensuring all ads are policy-compliant contribute to a healthier account baseline.

Also pay attention to your search impression share. If you are losing impression share due to Quality Score (rather than budget), it is a clear signal that relevance improvements are needed before increasing bids.

Quality Score Myths You Should Stop Believing

⠀

Several misconceptions circulate about Quality Score, and believing them can lead to wasted effort.

Myth 1: Pausing keywords resets their Quality Score. Paused keywords retain their Quality Score. When you reactivate them, the historical data comes back with them. If a keyword had a low score, pausing it does not help.

Myth 2: Quality Score directly determines Ad Rank. Quality Score is a component of Ad Rank, but it is not the only one. Bid, auction-time signals, and ad format also factor in. Focusing exclusively on Quality Score while ignoring bid strategy is a mistake.

Myth 3: A score of 7/10 is good enough. For highly competitive keywords, the difference between a 7 and a 10 can translate to hundreds or thousands of dollars in savings per month. Always push for improvement, especially on your highest-volume keywords.

Myth 4: Quality Score is calculated the same way for all keyword match types. Google evaluates Quality Score at the keyword level, but the auction-time quality signals adapt based on the actual search query matched. Broad match keywords therefore benefit from tight negative keyword lists that prevent irrelevant matches from damaging performance.

How to Track Quality Score Progress Over Time

⠀

Quality Score is not displayed in the standard Google Ads columns by default. You need to manually add it. Go to the Keywords tab, click the Columns button, and add Quality Score, Landing Page Exp., Ad Relevance, and Exp. CTR. This gives you full visibility into every component.

Because Quality Score updates dynamically as new data comes in, check it weekly rather than daily. Track your average Quality Score for top keywords in a spreadsheet. Over time, you want to see the average move toward 7–10 across your best-performing keywords.

Agencies like Blakfy use structured Quality Score audits as the first step in any PPC engagement — because fixing a poor score is often the highest-leverage action before increasing budget.

Frequently Asked Questions

⠀

Q: How long does it take to improve a Google Ads Quality Score?

A: It depends on impression and click volume. Keywords with high traffic can show changes within days of copy and landing page improvements. Low-volume keywords may take weeks to accumulate enough data for Google to update the score. Focus on high-volume keywords first for faster results.

Q: Does Quality Score affect Google Shopping campaigns?

A: Google Shopping does not use the same 1–10 Quality Score visible in search campaigns. However, Shopping campaigns have their own relevance signals — primarily product feed quality and landing page experience. Optimizing these improves Shopping performance in the same spirit as Quality Score optimization.

Q: Can a high Quality Score offset a low bid?

A: Yes, partially. Because Ad Rank = Bid × Quality Score (simplified), a significantly higher Quality Score can help a lower-bidding advertiser outrank a competitor with a higher bid but poor quality. However, in very competitive auctions, bid still plays a major role and there is a floor below which even a perfect Quality Score cannot compensate.
