Google Ads Quality Score
Quality Score is the single biggest lever you have over your cost per click. A score of 7+ can cut your CPC by 30-50% compared to a score of 5.
What Quality Score actually does to your CPC
Quality Score is a 1-to-10 rating Google assigns to each keyword in your account. It measures how relevant your ad and landing page are to that keyword. The score directly affects what you pay per click — not indirectly, not theoretically, directly.
Google multiplies your bid by your Quality Score to determine ad rank. A $3 bid with a Quality Score of 10 outranks a $5 bid with a Quality Score of 5. The advertiser with the lower bid and higher relevance wins a better position and pays less.
Here's roughly how Quality Score translates to CPC adjustments:
| Quality Score | CPC impact | What it means |
|---|---|---|
| 10 | ~50% discount | You pay half what an average advertiser pays |
| 8 | ~25% discount | Solid performance, meaningful savings |
| 7 | Baseline | This is the benchmark — roughly market rate |
| 5 | ~25% premium | You're overpaying compared to relevant competitors |
| 3 | ~67% premium | Google is actively penalizing your irrelevance |
| 1 | ~400% premium | You're paying 4x more per click — pause and fix this |
On a $5,000/month account, moving your average Quality Score from 5 to 7 saves $1,000-1,500 every month. Over a year, that's $12,000-18,000 in savings from the same traffic.
The three components (and which ones actually matter)
Google calculates Quality Score from three factors, each rated Above Average, Average, or Below Average. They are not equally important.
Landing page experience is the hardest to improve but has the biggest impact. Google evaluates page relevance, load speed (aim for under 3 seconds), mobile usability, and whether the content matches the search intent. A slow, generic homepage kills this score. A dedicated landing page that directly addresses the keyword boosts it.
Expected click-through rate (CTR) is the easiest to move. It predicts how likely someone is to click your ad for this keyword, based on your historical CTR adjusted for position. Better headlines, stronger calls to action, and tighter ad group structure all push this up.
Ad relevance is the most straightforward. It measures whether your ad copy matches the keyword's intent. The fix is simple: include the keyword in at least one headline, and make sure the ad copy addresses what someone searching that term actually wants. If someone searches "emergency plumber" and your ad talks about kitchen remodeling, ad relevance tanks — even if both services are yours.
How to improve each component
To improve expected CTR: Write headlines that speak directly to the search query. "Emergency Plumber — Here in 30 Minutes" beats "ABC Plumbing Services — Call Today." Test multiple responsive search ad variations. Tighten your ad groups so each group has 5-10 closely related keywords that the ad copy can actually speak to.
To improve ad relevance: Put the keyword (or a close variant) in your headlines. Match the ad's message to the searcher's intent. If an ad group contains keywords with different intents — "buy running shoes" and "running shoe reviews" — split it. One ad can't be relevant to both buying and research intent.
To improve landing page experience: Send users to a specific, relevant page — never your homepage. If someone searches "teeth whitening pricing," they should land on a page with teeth whitening pricing, not your general dentistry homepage. Load the page in under 3 seconds. Make it mobile-friendly. Include clear calls to action above the fold.
Quality Score myths that need to die
"Account-level Quality Score" is not real. Quality Score is calculated at the keyword level. Period. Some agencies claim there's an account-wide score that drags all your keywords down. Google has never confirmed this exists. Don't let anyone charge you for "account-level QS optimization."
Quality Score is not updated in real-time. It's a lagging indicator based on accumulated impression data. Don't check it hourly. Changes to ad copy take 1-2 weeks to reflect. Landing page changes take 2-4 weeks.
A low Quality Score on a low-volume keyword doesn't matter. If a keyword gets 10 impressions a month, obsessing over its Quality Score is a waste of time. Focus on high-spend keywords where the CPC impact actually adds up.
Where to start: the 80/20 of Quality Score improvement
Pull up your keywords, sort by cost descending, and filter to Quality Score below 7. Those are your highest-impact opportunities. For each one, check which component is Below Average and fix that specific thing.
In most accounts, the single biggest win is tightening ad group structure. When you have 30 keywords in one ad group, the ad copy can't be relevant to all of them. Split into groups of 5-10 related keywords, write ads that directly address each group, and watch relevance and CTR climb.
After that, focus on landing pages. Build dedicated pages for your highest-spend keyword themes. A personal injury firm with separate landing pages for "car accident lawyer," "slip and fall lawyer," and "medical malpractice lawyer" will have dramatically better Quality Scores than one that sends everything to a generic "practice areas" page.
How Fullrun optimizes Quality Score
Fullrun tracks Quality Score across every keyword in your account and pinpoints which component is holding each score back. It restructures ad groups for tighter relevance, rewrites ad copy to boost expected CTR, and flags landing pages that are dragging your scores down — then takes action automatically. Combined with daily negative keyword management to keep your CTR clean, the CPC savings compound month over month.
Frequently asked questions
- What is a good Quality Score?
- 7 or higher. At 7, you're paying roughly the baseline CPC. At 8-10, you're getting a discount of 15-50%. Below 5, you're paying a premium — and at 1-2, you're paying up to 4x what a high-Quality-Score advertiser pays for the same click.
- Does Quality Score directly affect my cost per click?
- Yes. Google uses Quality Score as a multiplier in the ad auction. Going from a Quality Score of 5 to 8 typically cuts your CPC by 30-50%. On a $5,000/month account, that's $1,500-2,500 saved — every single month.
- Can I see Quality Score for all my keywords?
- Yes. In Google Ads, go to Keywords, click the Columns icon, and add Quality Score plus the three sub-components: Expected CTR, Ad Relevance, and Landing Page Experience. Each is rated Above Average, Average, or Below Average. Sort by Quality Score ascending to find your worst performers first.
- How long does it take to improve Quality Score?
- Ad copy changes typically show up in 1-2 weeks. Landing page improvements take 2-4 weeks because Google needs a larger sample of post-click data. Low-volume keywords take longer because Google needs statistically significant impression data before updating the score.
- Is there an account-level Quality Score?
- No. Quality Score is calculated at the keyword level, period. Some agencies claim there's an 'account-level Quality Score' to justify their fees. Google has never confirmed this exists. Focus on improving individual keyword scores, especially on your highest-spend keywords.
- Does Fullrun monitor Quality Score?
- Yes. Fullrun tracks Quality Score across every keyword and identifies which component is dragging each score down. It rewrites ad copy to improve expected CTR, restructures ad groups to boost relevance, and flags landing page issues — then takes action automatically.
