Quality Score Fundamentals

What is Quality Score?

Quality Score is a 1-10 diagnostic metric that estimates the quality of your ads, keywords, and landing pages. It's calculated at the keyword level and composed of three sub-components.

Important: QS is a diagnostic tool, not a direct input to the auction. The actual auction uses real-time signals that are more granular than the 1-10 QS score.

The Three Components

Component	Weight (est.)	What It Measures	Data Source
Expected CTR	~39%	Likelihood of ad being clicked	Historical CTR, adjusted for position
Ad Relevance	~22%	How well ad matches search intent	Keyword-to-ad text relevance
Landing Page Experience	~39%	Post-click user experience	Page speed, content relevance, navigation

Each component is rated: Above Average, Average, or Below Average

QS to Component Mapping (Approximate)

QS	Expected CTR	Ad Relevance	Landing Page
10	Above Avg	Above Avg	Above Avg
9	Above Avg	Above Avg	Average
8	Above Avg	Average	Above Avg
7	Average	Above Avg	Above Avg
7	Above Avg	Above Avg	Below Avg
6	Average	Average	Above Avg
6	Above Avg	Average	Average
5	Average	Average	Average
4	Average	Below Avg	Average
4	Below Avg	Average	Average
3	Below Avg	Below Avg	Average
3	Average	Average	Below Avg
2	Below Avg	Below Avg	Below Avg
1	Below Avg	Below Avg	Below Avg

QS Impact on CPC and Ad Rank

Ad Rank Formula

Ad Rank = Max CPC Bid × Quality Score × Expected Impact of Extensions

Simplified for QS analysis:
Ad Rank ≈ Bid × QS

Actual CPC Formula

Actual CPC = (Ad Rank of advertiser below you / Your Quality Score) + $0.01

QS Impact on CPC (Relative to QS 5 Baseline)

Quality Score	CPC Modifier	CPC Impact
1	+400%	Pay 5× more
2	+150%	Pay 2.5× more
3	+67%	Pay 1.67× more
4	+25%	Pay 1.25× more
5	Baseline	Normal CPC
6	-17%	Save 17%
7	-29%	Save 29%
8	-38%	Save 38%
9	-44%	Save 44%
10	-50%	Save 50%

Financial Impact Example

Current state:
  Keywords: 500
  Avg QS: 5.2
  Monthly spend: $50,000
  Avg CPC: $3.20
  Clicks: 15,625

If improved to Avg QS 7.0:
  CPC reduction: ~29%
  New CPC: $2.27
  Same spend → 22,026 clicks (+41%)
  OR same clicks → $35,500 spend (-29%, saving $14,500/month)

GAQL Queries for QS Analysis

Query 1: Current QS Overview

SELECT
  ad_group.name,
  ad_group_criterion.keyword.text,
  ad_group_criterion.keyword.match_type,
  ad_group_criterion.quality_info.quality_score,
  ad_group_criterion.quality_info.creative_quality_score,

  change_event.change_date_time,
  change_event.change_resource_type,
  change_event.old_resource,
  change_event.new_resource,

  change_event.change_resource_type = 'AD_GROUP_CRITERION'
  AND change_event.change_date_time DURING LAST_30_DAYS
ORDER BY change_event.change_date_time DESC
LIMIT 1000

Improvement Playbooks

Playbook 1: Expected CTR (Below Average → Above Average)

Root cause: Your ads get clicked less often than competitors for the same queries.

Step 1: Analyze current ad copy

• Pull all active RSA headlines and descriptions
• Compare to top competitors (use Ad Preview tool)
• Look for missing elements: numbers, urgency, CTAs, unique value props

Step 2: Headline optimization

Winning headline patterns:

[Number] + [Benefit]: "Save 40% on Enterprise Plans"
[Urgency] + [Action]: "Limited Time — Start Free Trial"
[Social Proof]: "Trusted by 50,000+ Companies"
[Direct Answer]: "Fast Business Insurance Quotes"
[Differentiation]: "No Contracts, Cancel Anytime"

Step 3: Improve ad extensions

Extension	CTR Impact	Priority
Sitelinks (4+)	+10-20% CTR	Critical
Callouts (4+)	+5-10% CTR	High
Structured snippets	+3-8% CTR	High
Call extension	+5-15% CTR (mobile)	High (if phone business)
Price extensions	+5-10% CTR	Medium
Image extensions	+10-15% CTR	High
Lead form	Variable	Test for lead gen

Step 4: Match type alignment

• Exact match keywords should have highly specific ads
• Phrase match should have ads covering the concept
• Broad match should use responsive search ads with maximum headlines

Step 5: RSA pin strategy

• Pin your best-performing headline to Position 1
• Pin brand name headline to Position 2 or 3
• Don't pin descriptions (let Google optimize)
• Monitor "Ad strength" indicator (aim for "Good" or "Excellent")

Timeline: 2-4 weeks to see Expected CTR improvement after changes.

Playbook 2: Ad Relevance (Below Average → Above Average)

Root cause: Your ad text doesn't closely match the search intent of the keyword.

Step 1: Audit keyword-to-ad alignment

For each Below Average keyword:

1. Read the keyword
2. Read all headlines in the ad group's RSAs
3. Ask: "Does ANY headline contain this keyword or a close synonym?"

Step 2: Restructure ad groups

Tightly themed ad groups (STAG method):

Bad structure:
  Ad Group: "Shoes"
  Keywords: running shoes, dress shoes, hiking boots, sandals
  → Single ad can't be relevant to all of these

Good structure:
  Ad Group: "Running Shoes"
  Keywords: running shoes, buy running shoes, best running shoes
  Ad: Headlines include "Running Shoes" prominently

  Ad Group: "Dress Shoes"
  Keywords: dress shoes, formal shoes, men's dress shoes
  Ad: Headlines include "Dress Shoes" prominently

Step 3: Keyword insertion (use sparingly)

Headline: {KeyWord:Quality Shoes}

This dynamically inserts the user's search term into the headline. Use only when keyword grouping is tight. Avoid for brand-sensitive contexts.

Step 4: RSA headline variety with keyword focus

• Include the primary keyword verbatim in 2-3 headlines
• Include synonyms and related terms in 3-4 more headlines
• Include unique value props in remaining headlines
• Each headline should be distinct (no near-duplicates)

Timeline: 1-2 weeks for Ad Relevance to update after restructuring.

Playbook 3: Landing Page Experience (Below Average → Above Average)

Root cause: Your landing page doesn't meet user expectations after clicking the ad.

Step 1: Page speed audit

Metric	Target	Tool
Largest Contentful Paint (LCP)	< 2.5s	PageSpeed Insights
First Input Delay (FID)	< 100ms	PageSpeed Insights
Cumulative Layout Shift (CLS)	< 0.1	PageSpeed Insights
Time to First Byte (TTFB)	< 800ms	WebPageTest
Mobile speed score	> 50	PageSpeed Insights

Step 2: Content relevance

• Page headline must match ad headline closely
• Keywords from the ad group should appear in the page content
• The page should deliver on the ad's promise immediately (above the fold)
• Remove interstitials, pop-ups, and distractions

Step 3: Mobile experience

• Responsive design (no horizontal scrolling)
• Touch-friendly buttons (min 48×48px)
• Readable text without zooming (16px+ body font)
• Fast-loading images (WebP, lazy loading)

Step 4: Trust signals

• SSL certificate (HTTPS required)
• Privacy policy and terms of service links
• Contact information visible
• Social proof (reviews, testimonials, logos)
• Secure payment badges (if e-commerce)

Step 5: Navigation and transparency

• Clear navigation structure
• Easy-to-find contact information
• Transparent pricing (no hidden fees)
• Clear return/refund policy

Timeline: 4-8 weeks for Landing Page Experience to update (Google re-crawls landing pages periodically).

Historical QS Tracking Methodology

Why Track QS Over Time?

Google doesn't provide historical QS reports. You must build your own tracking system.

Method: Weekly QS Snapshot

1. Every Monday, run GAQL Query 1 (Current QS Overview)
2. Store results in a spreadsheet or database with columns:
   • Date, Campaign, Ad Group, Keyword, QS, Expected CTR, Ad Relevance, LP Experience, Impressions, Cost
3. Calculate weekly aggregates:
   • Impression-weighted avg QS = Σ(QS_i × Impressions_i) / Σ(Impressions_i)
   • % of keywords with QS ≥ 7
   • % of spend on QS ≥ 7 keywords

Key Tracking Metrics

Metric	Target	Calculation
Impression-weighted QS	≥ 7.0	Σ(QS × Impr) / Σ(Impr)
% keywords QS ≥ 7	> 60%	Count(QS ≥ 7) / Total keywords
% spend on QS ≥ 7	> 75%	Spend(QS ≥ 7) / Total spend
% keywords QS ≤ 3	< 5%	Count(QS ≤ 3) / Total keywords
QS improvement rate	Positive trend	Week-over-week change

Industry Benchmarks

Average Quality Score by Industry

Industry	Avg QS	Expected CTR (% Above)	Ad Relevance (% Above)	LP (% Above)
E-commerce	6.5	45%	55%	40%
SaaS / Technology	6.8	50%	60%	50%
Finance / Insurance	5.8	35%	45%	35%

Travel	6.3	42%	50%	45%
Local Services	6.1	38%	48%	38%
B2B Services	6.4	42%	52%	42%

QS Targets by Keyword Type

Keyword Type	Target QS	Rationale
Brand keywords	8-10	You ARE the most relevant result
High-intent transactional	7-9	Strong ad + landing page alignment
Non-brand generic	5-7	Competitive, harder to differentiate
Informational long-tail	4-6	Often mismatched landing pages
Competitor keywords	3-5	Intentionally lower (not your brand)

Examples

Example 1: High-Spend Low-QS Rescue

Scenario: Top 10 keywords by spend have avg QS of 4.2. Monthly spend: $25K on these keywords alone.

Analysis:

Keyword	QS	eCTR	AdRel	LP	Spend/mo
"project management software"	4	Below	Avg	Below	$4,200
"task management tool"	3	Below	Below	Below	$3,800
"team collaboration app"	5	Avg	Avg	Avg	$3,500
"workflow automation"	4	Avg	Below	Below	$3,200
...	...	...	...	...	...

Action plan:

1. Landing pages (LP Below × 4): Rebuild landing pages for top keywords. Add keyword in H1, speed optimization, mobile fixes. Timeline: 2 weeks.
2. Ad copy (eCTR Below × 3): Add 5 new headlines per ad group with keyword in headline, add all extensions. Timeline: 1 week.
3. Ad groups (AdRel Below × 3): Split "task management" and "workflow" into separate ad groups with tailored ads. Timeline: 1 week.

Projected impact (6-8 weeks):

• QS improvement: 4.2 → 6.5
• CPC reduction: ~25%
• Savings: ~$6,250/month
• Or: 33% more clicks for same budget

  "sales pipeline" — QS 4, eCTR Below, $1,800/mo spend

Example 3: Competitor Keyword QS Strategy

Scenario: Bidding on 50 competitor brand keywords. Avg QS: 3.1. Should we continue?

Analysis:

• Competitor keywords inherently have lower QS (Google prefers the brand owner)
• Expected QS range for competitor terms: 3-5
• CPC premium: 2-3× higher than non-brand generics

Decision framework:

Condition	Action
CPA on competitor terms < 1.5× non-brand CPA	Continue, it's profitable
CPA on competitor terms 1.5-2.5× non-brand CPA	Selective — keep top 10 converters
CPA on competitor terms > 2.5× non-brand CPA	Pause and reallocate budget

QS improvement for competitor keywords:

• Use competitor comparison landing pages
• Headlines: "Better Than [Competitor]" or "[Your Brand] vs [Competitor]"
• Include comparison tables, switch-from guides
• Realistic target QS: 4-5 (not 7+)
