A low Quality Score is a symptom, not a cause. It signals that something in your account is misaligned with what Google expects: either your keywords, ads, and landing pages don't fit together logically, or your ad copy isn't resonating with search intent. Fixing the wrong problem wastes time and budget. This post walks you through isolating whether your Quality Score pain is structural (account organization) or textual (ad copy), so you can prioritize the fix that matters.
Why This Distinction Matters
Account structure and ad copy feed different signals to Google's Quality Score algorithm. Structure determines relevance at the keyword level. Ad copy determines click-through rate (CTR) and user engagement. Both affect your score, but they require different fixes.
If your structure is broken (keywords grouped with unrelated ads, or landing pages that don't match intent), you can write perfect ad copy and still see mediocre Quality Scores. If your structure is sound but ad copy is generic or unclear, you'll see lower CTR and weak engagement metrics, dragging the score down despite good relevance.
Diagnosing correctly means you fix the bottleneck first, not the symptom.
Quick Diagnostic: Check Your Account Structure First
Account structure is the foundation. Start here because a structural fix often lifts Quality Scores across multiple ad groups at once.
Open your Google Ads account and navigate to the Campaigns tab. Select one campaign with low Quality Scores. Then examine these three layers:
- Campaign to ad group fit: Does each ad group have a clear, single topic? For example, one ad group for "blue running shoes" and a separate one for "trail running shoes," not both mixed together.
- Keywords to ad copy fit: Do all keywords in an ad group appear naturally in at least one of your ads? If you're bidding on "affordable blue running shoes" but your ad only says "Running Shoes On Sale," there's a gap.
- Ad copy to landing page fit: Do your ads promise what the landing page delivers? If your ad highlights "free shipping," does the landing page mention it in the first fold, or does the user have to search for it?
Run through this checklist for three low-scoring ad groups. If you find mismatches in all three layers, structure is your primary problem.
Structural Red Flags: Signs Your Account Organization Is the Issue
These patterns indicate that account structure is dragging down your Quality Scores.
Broad keyword groupings in one ad group. You have 50+ keywords in a single ad group covering multiple topics (e.g., "running shoes," "trail shoes," "cross-training shoes" all in one ad group). Google cannot match keywords to relevant ads when the ad group is too wide. Result: low relevance scores across the board.
Generic ads that don't match keyword intent. Your ad group bids on "emergency plumber near me" and "24-hour plumber," but your ad says only "Plumbing Services." Neither keyword appears in the headline or description. Google sees low relevance between the search query and the ad.
Landing pages that don't align with keyword promises. Your ad group bids on "blue running shoes size 10" but sends all traffic to a generic "shoes" category page, not a filtered product page. The user lands on a page where they have to search again. Bounce rate spikes, dwell time drops, and Google penalizes relevance.
One ad group per campaign. All keywords and ads live in a single ad group. This is the most extreme structure issue. Google cannot differentiate relevance between keyword and ad, so Quality Scores stay flat and low.
Quality Scores consistently low across all ad groups in a campaign. If you see Quality Scores of 4–6 across the board (not just one ad group), structure is likely the culprit. Ad copy issues typically affect individual ad groups or campaigns, not the entire account uniformly.
How to Fix Structure Problems
Restructuring takes time but pays off quickly. Start with your lowest-performing campaign.
Step 1: Group keywords by intent and topic. Create new ad groups. One ad group should contain keywords that would use the same ad. For example, group "blue running shoes," "cobalt running shoes," and "navy running shoes" together (same product, same intent). Create a separate ad group for "running shoe reviews" or "best running shoes for flat feet" (different intent, different ad needed).
Step 2: Write ads that match each ad group's keywords. Include the primary keyword or a close variant in at least one headline. If your ad group is about "affordable blue running shoes," your headline should include "blue" or "affordable" or both. Avoid generic language.
Step 3: Map landing pages to ad group intent. If your ad group bids on "blue running shoes size 10," send that traffic to a product page filtered for blue shoes and size 10, not a category page. Use URL parameters or landing page variants to ensure the user lands where the ad promised.
Step 4: Monitor Quality Score changes. After restructuring, give the ad group 1–2 weeks of traffic (at least 100 impressions) for Google to re-evaluate. You should see Quality Score improvements if structure was the issue.
Ad Copy Red Flags: Signs Your Ad Text Is the Problem
If your account structure is sound but Quality Scores remain low, weak ad copy is likely the culprit.
Low click-through rate relative to industry benchmarks. Check your campaign's average CTR. If it's below 2% for search (industry average is 3–5% depending on vertical), your ads aren't compelling enough. Users see your ad and skip it. Google interprets low CTR as low relevance.
High impression share but low CTR. Your ads show up frequently, but few people click. This signals that your ad copy isn't differentiating you from competitors or isn't matching user expectations set by the search query.
One or two ads in an ad group, unchanged for months. Stale ads perform worse over time. Users who see the same ad multiple times are less likely to click. If you haven't tested new ad copy in 3+ months, ad copy is likely the problem.
Quality Scores improve after ad restructuring but plateau. You fixed structure, Quality Scores went from 4 to 6, but now they're stuck. Ad copy is the next lever. Your structure is sound, but your ads aren't compelling enough to push Quality Scores higher.
One ad group has a low Quality Score while similar ad groups perform well. This is a classic ad copy signal. The structure is fine (other ad groups prove it), but the underperforming ad group's ads are weaker, less relevant, or missing key messaging.
How to Fix Ad Copy Problems
Ad copy improvements are faster to test than structural changes. Start with your lowest-CTR ad groups.
Step 1: Include the primary keyword in at least one headline. If your ad group bids on "affordable running shoes," use "Affordable Running Shoes" or "Budget Running Shoes" in a headline. Exact match isn't required, but the concept should appear.
Step 2: Write benefit-driven descriptions. Instead of "We sell running shoes," write "Free shipping on orders over $50. Same-day delivery in select areas." Show the user why they should click your ad, not just what you sell.
Step 3: Match the tone to the search intent. If the keyword is "emergency plumber," your ad tone should be urgent and reassuring, not casual. If the keyword is "best budget running shoes," your tone should be helpful and comparative, not salesy.
Step 4: Test multiple ad variations. Google Ads lets you create 3 headlines and 2 descriptions per ad. Use different combinations: one ad emphasizes price, another emphasizes speed, another emphasizes selection. Let Google's system show the best-performing combo to users. Test for 2–4 weeks before drawing conclusions.
Step 5: Monitor CTR and Quality Score weekly. After deploying new ad copy, track CTR changes in your ad group. CTR improvements typically appear within 1–2 weeks. Quality Score updates may lag by a few days.
The Diagnostic Workflow: Which Problem Are You Solving?
Use this simple decision tree to pinpoint your bottleneck:
- Open a low-scoring ad group. Count the number of unique keyword topics. If it's more than three distinct topics (e.g., product type, location, price range, use case all mixed), structure is the problem. Reorganize ad groups.
- If structure looks clean (keywords are tightly grouped), check your three most recent ads. Do they include the primary keyword or a close variant? If not, ad copy is the problem. Rewrite ads.
- If ads include the keyword, check your landing page. Does it match the ad's promise in the first fold? If not, structure is the problem. Update landing page routing.
- If structure and landing pages align, check your CTR. Is it below 2%? If yes, ad copy is the problem. Test new ad variations.
- If CTR is healthy (above 3%) but Quality Score is still low, check your account for other signals (bid strategy misalignment, negative keywords missing, or recent account changes). This is less common but possible.
Most accounts have both problems to some degree. The diagnostic workflow helps you fix the bigger bottleneck first. Structure fixes typically yield faster Quality Score gains than ad copy alone, so prioritize structure if both are broken.
Reality Check: What This Approach Won't Fix
Quality Score is influenced by factors beyond structure and ad copy. If you fix both and Quality Scores still don't improve, check these:
Landing page experience: Google measures page speed, mobile usability, and content clarity. A slow or poorly designed landing page can suppress Quality Scores even with perfect ads and structure. Test your landing page in Google PageSpeed Insights and fix any "Poor" or "Needs Improvement" scores.
Account history: If your account has a history of low Quality Scores, high bounce rates, or poor conversion rates, Google may be cautious even after improvements. Quality Score recovery can take 2–4 weeks of consistent good performance.
Bid strategy and budget: Underbidding or running out of budget can suppress impressions and CTR, which indirectly affects Quality Score perception. Make sure your bids are competitive for your target keywords.
Competitive landscape: If competitors have higher-quality ads or landing pages, your Quality Scores may be lower regardless of your effort. Audit your top 3 competitors' ads and landing pages to benchmark your own.
What to Do Next
Start with one low-performing campaign. Run through the diagnostic workflow above. Identify whether structure or ad copy is the primary bottleneck. Fix that first. Give it 1–2 weeks of traffic, then re-evaluate. If you need help auditing your entire account structure or running a full Quality Score assessment, a Google Ads audit can accelerate the diagnosis.
FAQs
How long does it take to see Quality Score improvements after fixing structure?
Google typically re-evaluates Quality Score within 1–2 weeks of structural changes, assuming your ad group receives at least 100 impressions. Larger changes may take longer.
Can I have a high Quality Score with low CTR?
No. CTR is a major factor in Quality Score. If CTR is low, Quality Score will be low, even if structure and landing pages are perfect.
Should I restructure my entire account at once or do it campaign by campaign?
Campaign by campaign is safer. It lets you test changes and avoid disrupting your entire account. Start with your lowest-performing campaign.
What's the ideal number of keywords per ad group?
10–20 tightly themed keywords per ad group is typical. Fewer is fine if they're highly specific. More than 30 is usually a sign of poor organization.
People Also Ask
What is Quality Score in Google Ads?
Quality Score is Google's rating of the relevance and quality of your keywords, ads, and landing pages on a scale of 1–10. It affects your cost per click and ad rank. Higher scores mean lower costs and better ad placement.
How does Quality Score affect my Google Ads cost?
Quality Score directly impacts your cost per click (CPC). A higher Quality Score can lower your CPC by 50% or more compared to a lower score bidding on the same keyword. It also affects your ad rank, determining whether your ad shows at all.
Can I see Quality Score for individual keywords?
Yes. In Google Ads, go to Keywords tab, select Columns, and add Quality Score. You'll see a 1–10 rating for each keyword, plus historical trends.
What's the average Quality Score?
Google doesn't publish an official average, but most accounts see Quality Scores between 5–7. Scores above 8 are considered excellent and are typical for highly optimized, mature accounts.
Does Quality Score affect organic search rankings?
No. Quality Score only applies to Google Ads (paid search). It doesn't affect your organic search rankings. Those are determined by separate SEO factors.
How often does Google update Quality Score?
Google updates Quality Score continuously as your ads receive impressions and clicks. However, visible changes in the UI may take 1–2 weeks to reflect.
Can I improve Quality Score by increasing my bid?
Increasing your bid alone won't improve Quality Score. Quality Score is based on relevance and performance, not spend. However, higher bids can increase impressions, which may give Google more data to evaluate your ads fairly.
What's the difference between Quality Score and Ad Strength?
Quality Score rates keyword and ad relevance on a 1–10 scale. Ad Strength rates how well your ad copy and assets are put together (Poor, Average, Good, Excellent). They're separate metrics that both affect performance.
