What Is Quality Score?

QUALITY SCORE FUNDAMENTALS
══════════════════════════

Quality Score = Google's assessment of your ad quality
Score: 1-10 (10 = best)

Google uses REAL-TIME quality signals in every auction.

Quality Score Impact

QS and CPC Relationship

QUALITY SCORE IMPACT ON CPC
════════════════════════════

FORMULA:
Ad Rank = Max CPC x Quality Score (simplified)
Actual CPC = (Ad Rank of advertiser below you / Your QS) + 0.01

┌────────────────┬─────────────────┬──────────────────────────────┐
│ Quality Score  │ CPC Impact      │ Comparison (base QS=5)       │
├────────────────┼─────────────────┼──────────────────────────────┤
│ QS 10          │ -50% CPC        │ Pay half for same position   │
│ QS 8           │ -25% CPC        │ Significant advantage        │
│ QS 7           │ -15% CPC        │ Small advantage              │
│ QS 5           │ Baseline        │ Average                      │
│ QS 3           │ +35% CPC        │ Disadvantage, inefficient    │
│ QS 1           │ +400% CPC       │ Not competitive              │
└────────────────┴─────────────────┴──────────────────────────────┘

PRACTICAL EXAMPLE:
────────────────────
Keyword: "buy running shoes"
Market average CPC: $1.00

├── With QS 10: You pay ~$0.50
├── With QS 7:  You pay ~$0.85
├── With QS 5:  You pay ~$1.00 (baseline)
├── With QS 3:  You pay ~$1.35
└── With QS 1:  You pay ~$5.00 (often not shown)

ANNUAL IMPACT ($50k ad spend):
──────────────────────────────
QS 5 → QS 7:  Save ~$7,500/year
QS 5 → QS 8:  Save ~$12,500/year
QS 5 → QS 10: Save ~$25,000/year

Expected CTR Optimization

CTR Improvement Strategies

CTR OPTIMIZATION FRAMEWORK
═══════════════════════════

1. HEADLINE OPTIMIZATION
─────────────────────────
HIGH-CTR HEADLINE FORMULAS:

□ Include Keyword (Direct Match)
├── Keyword: "women's running shoes"
├── Headline: "Women's Running Shoes - Shop Now"
└── Impact: +20-40% CTR

□ Numbers & Specifics
├── "50+ Running Shoe Models"
├── "Starting at $49.95"
├── "4.8 Star Rating"
└── Impact: +15-30% CTR

□ Urgency/Scarcity
├── "Same-Day Delivery"
├── "This Week Only -30%"
├── "Last Items"
└── Impact: +10-25% CTR (use sparingly)

□ Power Words
├── "Free Shipping"
├── "Authorized Dealer"
├── "100% Authentic"
└── Impact: +10-20% CTR

2. DESCRIPTION OPTIMIZATION
────────────────────────────
□ First 90 characters = most visible
□ Include primary keyword
□ Clear CTA (Shop Now, Order Direct)
□ Benefit-focused, not feature-focused
□ Social proof (reviews, awards)

3. AD ASSETS IMPACT (formerly "Extensions")
────────────────────────────────────────────
Assets increase visual footprint = higher CTR
Note: Google rebranded "Extensions" to "Assets" in 2022.
The Google Ads API uses asset_group for PMax,
ad_group_ad_asset_view for Search ads.

CTR IMPACT PER ASSET TYPE:
├── Sitelinks: +10-15%
├── Callouts: +5-10%
├── Structured Snippets: +5-8%
├── Call Asset: +5-10%
├── Location Asset: +5-10%
└── Price Asset: +10-20%

USING ALL ASSETS = Up to +30% CTR boost
