If you've ever wondered why two advertisers bidding the same amount end up paying very different costs per click — or why one ad appears at the top of the page while the other barely shows up at all — the answer almost always comes down to Quality Score.

Quality Score is one of Google's most important (and most misunderstood) metrics. Get it right, and you can outrank bigger competitors while spending less. Ignore it, and you'll keep burning budget without knowing why.

In this guide, we'll break down exactly what Quality Score is, how it's calculated, and the proven strategies you can use to improve it — so your campaigns become more efficient, more visible, and more profitable.

What Is Google Ads Quality Score?

Quality Score is a diagnostic metric Google assigns to each keyword in your account, on a scale of 1 to 10. A score of 10 is the best possible, while 1 indicates your ads are highly misaligned with what users are searching for. Google uses Quality Score as one of the primary inputs in its Ad Rank formula — the algorithm that determines where your ad appears on the search results page and how much you actually pay per click.

Here's the key insight: a higher Quality Score means lower costs and better ad positions. You can outbid a competitor in terms of raw spend and still lose the top spot if their Quality Score is significantly higher than yours.

Quality Score is determined by three core components:

Expected Click-Through Rate (CTR):

How likely Google thinks your ad is to be clicked when shown for a given keyword, compared to other advertisers.

Ad Relevance:

How closely your ad copy matches the intent behind the search query.

Landing Page Experience:

How relevant, useful, and trustworthy your landing page is for someone who clicks your ad. Each of these components is rated as "Above Average," "Average," or "Below Average." Improving all three is how you push your Quality Score higher — and your costs lower.

Why Quality Score Matters More Than Your Bid

Most advertisers focus almost entirely on their bids. That's understandable — it feels like the most direct lever to pull. But Google's Ad Rank formula actually multiplies your bid by your Quality Score (along with other factors like ad extensions). This means that a modest bid paired with a high Quality Score can easily beat a much larger bid with a poor Quality Score.

The practical implication: a Quality Score of 8–10 can reduce your cost per click by 30–50% compared to a score of 4–5. That's money staying in your pocket on every single click, every single day your campaigns run. At Praxxii Global, improving Quality Score across client accounts is one of the first things we tackle — because the ROI compound effect is enormous over the life of a campaign.

How to Check Your Quality Score Before you can improve your Quality Score, you need to see it. Here's how:

Navigate to your Google Ads account and click on Keywords in the left sidebar. Then click the column icon and add the following columns: Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience. This gives you a breakdown of every keyword's score and its three component ratings, so you know exactly where the problem lies.

Focus first on high-spend, low-score keywords — these are where improvements will have the biggest financial impact.

7 Proven Strategies to Improve Your Quality Score

1. Tighten Your Ad Groups

One of the most common causes of low Quality Scores is overstuffed ad groups. When you pack dozens of loosely related keywords into a single ad group and write one generic ad to cover them all, relevance suffers — and so does your score. The fix is to use Single Keyword Ad Groups (SKAGs) or tightly themed ad groups containing 3–5 closely related keywords. This allows you to write highly specific ad copy that directly mirrors each keyword, which dramatically improves both Expected CTR and Ad Relevance. Yes, this means more ad groups to manage. But the performance gains are worth it — and tools like Google Ads Editor make bulk management much easier.

2. Write Ad Copy That Mirrors Search Intent

Your ad copy needs to speak directly to what the user typed. If someone searches for "affordable Google Ads management for small business," your headline should reflect those specific themes — not something generic like "Digital Marketing Services." Use your target keyword in the first headline whenever possible. Google bolds keywords that match the search query, which makes your ad stand out and signals strong relevance. Write compelling descriptions that address the user's pain point and include a clear call to action.

Responsive Search Ads (RSAs) are a useful tool here — they allow you to input up to 15 headlines and 4 descriptions, and Google tests combinations to find the best-performing pairings. Over time, this improves Expected CTR as better-performing combinations are shown more often.

3. Optimise Your Landing Page for Relevance

This is where many advertisers lose Quality Score points without realising it. You can have a brilliant ad with a great CTR, but if the landing page doesn't deliver on what the ad promised, your Landing Page Experience score will suffer.

Your landing page should:

  • Clearly reflect the keyword and ad copy themes above the fold
  • Load quickly on both desktop and mobile (Google's PageSpeed Insights is a free tool to check this)
  • Be easy to navigate with a clear call to action
  • Contain original, useful content — not thin copy or duplicate content
  • Be secure (HTTPS) and free from intrusive pop-ups or misleading elements

If you're running Google Ads management services for multiple products or services, never send all traffic to your homepage. Use dedicated, purpose-built landing pages for each ad group or campaign.

4. Improve Your Historical Click-Through Rate

Expected CTR is partly based on your historical performance data. Ads that have consistently earned high click-through rates are rewarded with better Expected CTR scores going forward.

To improve CTR:

Use ad extensions generously — sitelinks, callouts, structured snippets, and call extensions all expand your ad's real estate and increase click opportunities Test ad copy variations constantly and pause underperformers Include numbers, percentages, or specific offers in your headlines ("Save 30%", "Free Consultation", "Results in 30 Days") Use emotional or benefit-driven language that speaks to outcomes, not just features

5. Use Negative Keywords Strategically

Irrelevant clicks don't just waste money — they drag down your CTR, which in turn harms your Expected CTR score. If your ads are showing for searches that aren't a great match, your click-through rate suffers even if the ad itself is well-written. Build a thorough negative keyword list to exclude searches that are unlikely to convert. Review your Search Terms report weekly and add negatives at both the campaign and ad group level. Common categories of negatives include competitor brand terms (if not intentionally targeting them), overly broad informational queries, and location terms outside your service area. This is a core part of our PPC management process at Praxxii Global — and it consistently delivers measurable improvements in Quality Score within the first 30 days.

6. Align Keyword Match Types with Intent

Broad match keywords can generate a lot of impressions from tangentially related searches — many of which won't convert and will lower your CTR. While broad match has its place in discovery campaigns, it should be used carefully with strong negative keyword coverage. Phrase match and exact match keywords tend to produce higher CTRs because they match more specific, intent-driven searches. When structuring campaigns aimed at improving Quality Score, lean toward phrase and exact match for your core converting keywords.

7. Improve Page Load Speed

Google explicitly factors mobile usability and page speed into Landing Page Experience. If your landing page takes more than 3 seconds to load on mobile, you're likely losing points on this component — and losing conversions too. Use Google's free PageSpeed Insights tool to diagnose speed issues. Common fixes include compressing images, reducing unnecessary JavaScript, enabling browser caching, and upgrading to faster hosting. Even shaving a second off your load time can meaningfully improve both Quality Score and conversion rates.

What Quality Score Is Not

It's important to understand what Quality Score doesn't measure. It's not a direct reflection of your conversion rate, your campaign profitability, or the quality of your product. A campaign can have excellent Quality Scores and still perform poorly if the offer isn't compelling, the targeting is off, or the sales process breaks down after the click. Use Quality Score as a diagnostic tool — a signal of how well your ads and landing pages are aligned with user intent — not as the sole measure of campaign success.

How Long Does It Take to See Improvements?

Quality Score updates continuously as Google collects data on your ads' performance. After making significant changes — rewriting ad copy, restructuring ad groups, improving landing pages — you can often see Quality Score movement within 2–4 weeks, provided your keywords are generating enough impressions. High-volume keywords will update faster. Low-traffic keywords may take longer to accumulate enough data for the score to shift. Be patient, keep testing, and prioritise your highest-spend keywords first.

The Compound Effect of a Better Quality Score

Here's what makes Quality Score improvement so powerful as a long-term strategy: the benefits compound. As your scores improve, your Ad Rank improves. Better Ad Rank means better positions. Better positions generate more clicks. More clicks generate more performance data. More performance data refines your Expected CTR further. Over time, accounts with consistently high Quality Scores become significantly more efficient than those that rely on brute-force bidding. You get more visibility, more clicks, and more conversions — often for less money. This is why Quality Score optimisation is a foundational part of how we manage Google Ads campaigns for our clients at Praxxii Global.
