Google Ads Quality Score in 2026: What Actually Affects It

Quality Score is the metric advertisers obsess over and the metric that means the least to your actual results in 2026.

That's a strange combination. Let's untangle it.

Quality Score is Google's 1-10 rating shown for each keyword in your account. It's calculated based on three components:

• Expected click-through rate
• Ad relevance to the keyword
• Landing page experience

Higher Quality Score = lower CPCs (theoretically). Most advertisers fixate on improving Quality Score from 6 to 7, expecting magical performance improvements. They rarely see them.

Here's why — and what to focus on instead.

What Quality Score actually represents

Quality Score is a snapshot of historical performance for each keyword, scored on a 1-10 scale. It's calculated AFTER auctions happen, based on what already occurred.

The auction itself uses different metrics — Ad Rank, Expected CTR, expected impact of extensions, all calculated in real-time per query. These are WAY more dynamic than the Quality Score number you see in your interface.

So when you "improve" your Quality Score from 6 to 7, you've usually already had improving performance — the score is reflecting it, not causing it.

This is why obsessing over Quality Score directly is mostly cargo-cult optimization. The interventions that improve Quality Score are the same interventions that improve auction performance directly. Doing them produces results regardless of whether the Quality Score number changes.

The three Quality Score factors, explained

1. Expected CTR (most important)

Google predicts how likely your ad is to be clicked when shown for a query. Higher predicted CTR = higher Quality Score component.

Predicted CTR is influenced by:

• Historical CTR for this keyword in your account
• Ad relevance to the specific query
• Ad copy quality (specific, compelling, benefit-driven)
• Position bid (higher positions get higher CTR baselines)

2. Ad Relevance

How closely your ad copy matches the search query.

Optimized for:

• Including the keyword in your headline (literal match preferred)
• Mentioning the user's specific search intent
• Avoiding generic claims that don't address the query

3. Landing Page Experience

How your destination page is judged on:

• Relevance to the query (mentions the same thing the ad mentions)
• Load speed (especially on mobile)
• Mobile-friendliness
• Original content (not duplicate or thin)
• Easy navigation
• Trust signals (HTTPS, real contact info, professional design)
• No deceptive content or pop-ups

The 2026 changes most people don't know about

Quality Score has evolved in subtle but important ways since 2020:

1. Mobile experience matters more than ever

In 2026, mobile traffic is 65-75% of most accounts. Google's Quality Score weights mobile landing page experience heavily. A site that loads in 2 seconds on desktop but 6 seconds on mobile gets penalized — heavily.

2. Core Web Vitals integration

Google's page experience signals (LCP, INP, CLS) now feed directly into Quality Score's landing page component. If your Core Web Vitals are poor, your Quality Score will be capped at 5-6 even with perfect ad copy.

3. AI-generated content detection

Google's algorithms in 2026 detect AI-generated landing page content. Pages that are obviously LLM-spun without human editing get reduced landing page experience scores. Original, human-edited content always wins.

4. Brand recognition impact

For high-volume brands with strong organic search presence, Quality Scores tend to be higher across the board. This is partly because their ads have established CTR patterns and partly because brand familiarity drives click behavior.

What actually moves Quality Score

If you want to improve Quality Score (and the resulting auction performance), here's what works:

High-leverage actions:

1. Match keywords to specific ad groups — one ad group should target one tight cluster of keywords. Don't put 50 different keywords in one ad group with one generic ad.

2. Include the keyword in the headline — Google literally tells you to do this. If your keyword is "personal injury attorney Boston," your headline should contain "Personal Injury Attorney" or "Boston Personal Injury."

3. Match landing page to keyword — the page someone lands on after clicking should mention the same thing the ad mentioned. Sending "personal injury attorney Boston" traffic to a generic homepage hurts your score.

4. Improve mobile load speed — anything over 3 seconds is hurting you. Use Google's PageSpeed Insights to diagnose.

5. Increase ad relevance through specificity — generic ads ("expert legal services") perform worse than specific ones ("Hit by a rideshare driver in Boston? Free case review.")

Medium-leverage actions:

1. Use Responsive Search Ads with 15 headlines — Google needs variety to optimize. Single ads with 3 headlines hurt RSA performance.

2. Run sitelink, callout, and structured snippet extensions — extension usage signals account quality.

3. Maintain a healthy negative keyword list — protects your ads from showing for irrelevant queries (which would hurt CTR predictions).

Low-leverage actions (mostly waste of time):

1. Adjusting Quality Score directly — you can't. It's a calculated metric based on actions.

2. Pausing low-Quality-Score keywords — sometimes correct, but often you're just hiding a problem instead of fixing it.

3. Bidding higher to "force" higher Quality Score — this doesn't work. Quality Score is calculated independently of bid.

Quality Score vs. Ad Strength — what to focus on

Most accounts in 2026 should focus on Ad Strength (the dynamic indicator on each Responsive Search Ad) more than Quality Score.

Ad Strength updates in real-time based on your ad copy variety, relevance, and quality. It directly tells you what to fix:

• "Add more headlines" — do it
• "Make headlines more unique" — do it
• "Include popular keywords" — do it
• "Make headlines more specific" — do it

Improving Ad Strength from "Average" to "Excellent" reliably improves Quality Score AND auction performance. It's a more useful target than the Quality Score number itself.

When low Quality Scores are actually fine

Counterintuitive: sometimes low Quality Scores don't matter.

Examples:

• Brand campaigns: You'll always rank #1 for your brand regardless of Quality Score because no one else is competing as hard for it.
• Niche specialty terms: If you're the only meaningful advertiser for "amish furniture restoration Boston," low competition means you'll rank fine even at QS 5.
• High-margin commerce: If your average sale is $3,000 and your CPC is $4 on a QS 6 keyword, the math works regardless.

Don't optimize Quality Score for its own sake. Optimize for profitable auctions.

Quality Score by match type — the dirty secret

Match type significantly affects Quality Score:

• Exact match keywords typically have highest Quality Scores (better CTR, more relevant clicks)
• Phrase match has middle Quality Scores
• Broad match has the lowest (more irrelevant impressions)

If you have a broad match keyword with QS 4, that doesn't mean the keyword is bad — it might mean the broad match interpretation is bad. Switching to phrase match often jumps QS by 2-3 points overnight.

Quality Score check-in routine

Once a month, run this 15-minute review:

1. Go to Google Ads → Keywords
2. Customize columns to show Quality Score, plus the three components (Exp CTR, Ad Relevance, Landing Page Experience)
3. Filter by keywords with QS 4 or below
4. For each one, identify which component is weakest:
   • Exp CTR weak? Improve ad copy, especially the headline
   • Ad Relevance weak? Add this keyword to the headline or first description
   • Landing Page Exp weak? Send traffic to a more relevant page

Don't try to fix everything at once. Pick the worst 5-10 keywords each month and improve them.

What about Display and YouTube Quality Score?

Display and Video have their own quality scoring, but they're less transparent than Search Quality Score. Focus less on the metric itself and more on:

• Audience signal quality (proper Customer Match data, well-configured audiences)
• Creative quality (clear visuals, strong CTAs, mobile-first)
• Frequency caps (don't spam the same person 20 times)
• Placement quality (block placements that aren't converting)

The compound effect of Quality Score work

While individual Quality Score improvements feel small, they compound:

• 1-point QS improvement = 10-15% lower CPC on average
• Lower CPC = more clicks within the same budget
• More clicks = more conversion data for Smart Bidding
• More conversion data = better algorithm decisions
• Better decisions = higher conversion rate
• Higher conversion rate = higher predicted CTR
• Higher predicted CTR = higher Quality Score
• ... cycle continues

Accounts that maintain disciplined ad-keyword-landing-page alignment compound these gains over time. Accounts that don't get stuck in mediocre Quality Score forever, paying 20-30% more per click than they should.
