Calculating true AI Overview impact

Baseline establishment methodology

Accurately measure AIO impact through proper baseline comparison:

Pre-AIO performance benchmarking

Data collection period: 90 days before AIO launch
Metrics to capture:
- Daily organic impressions
- Daily organic clicks
- Average CTR by query type
- Position distribution
- Seasonal adjustment factors

Control group identification

Keywords that don't trigger AIOs as control group
Similar search volume and competition levels
Same content types and user intent
Consistent tracking period for valid comparison

Impact calculation formulas

Use these calculations for accurate impact assessment:

Basic CTR impact calculation

AIO Impact % = ((AIO Period CTR - Baseline CTR) / Baseline CTR) × 100

Example:
Baseline CTR: 2.5%
AIO Period CTR: 1.8%
Impact: ((1.8 - 2.5) / 2.5) × 100 = -28%

Volume-adjusted impact analysis

Weighted Impact = (Query Volume × CTR Change) / Total Volume

For multiple queries:
Total Impact = Σ(Query Volume × CTR Change) / Total Portfolio Volume

Statistical significance testing

Sample size calculation:
n = (Z² × p × (1-p)) / E²

Where:
Z = confidence level (1.96 for 95%)
p = baseline CTR
E = margin of error (typically 0.01-0.05)

Advanced measurement techniques

Cohort analysis for AIO impact

Track different groups of keywords over time:

Query intent cohorts

Informational queries: How-to, what-is, guide content
Commercial investigation: Best-of, comparison content
Navigational queries: Brand and product searches
Transactional queries: Purchase-focused terms

Content type cohorts

Blog posts and editorial content
Product pages and commercial content
Tool pages and interactive resources
Local business and service pages

Revenue impact analysis

Measure business impact beyond traffic metrics:

Revenue attribution modeling

Revenue Impact = (Traffic Change × Conversion Rate × Average Order Value)

Example calculation:
- 1000 sessions lost to AIO
- 3% conversion rate
- $100 average order value
- Revenue impact: 1000 × 0.03 × $100 = $3,000 lost

Customer lifetime value considerations

LTV Impact = (Customer Acquisition Change × Average LTV)

Factors to consider:
- Long-term customer value
- Retention rates by traffic source
- Upsell/cross-sell potential
- Brand building value of AIO citations
