Fundamentals of Test Documentation
001. Formulate Test Hypotheses
Every test begins with a clear, measurable hypothesis. This should be specific, testable and relevant to SEO goals.
Example Hypothesis:
"If we extend the meta description from 120 to 160 characters, then CTR will increase by at least 5% within 4 weeks."
002. Define Test Parameters
All relevant parameters must be established before test start:
- Test Duration: At least 4 weeks for statistical significance
- Metrics: CTR, Rankings, Traffic, Conversions
- Control Group: Comparison pages without changes
- Test Group: Pages with planned changes
Test Parameters
8 points: Hypothesis, Duration, Metrics, Control Group, etc.
003. Capture Baseline Metrics
Before any change, current values must be documented:
Test Documentation in Practice
001. Create Test Protocol
A structured protocol should contain the following elements:
Test Information:
- Test ID and Name
- Start and End Date
- Responsible Person
- Status (Running/Completed/Aborted)
Hypothesis:
- Clear formulation of expected effect
- Justification based on SEO theory or experience
Methodology:
- Description of implemented changes
- Technical details of implementation
- Tools and tracking methods

002. Systematically Capture Results
During the test, data must be collected regularly:
Daily Measurements:
- Ranking positions for target keywords
- Technical metrics (Core Web Vitals)
- Crawling status
Weekly Measurements:
- Traffic development
- CTR changes
- Conversion rate
Monthly Measurements:
- Comprehensive performance analysis
- Comparison with control group
- Statistical significance testing
003. Document Disturbing Factors
External influences can distort test results:
- Google Updates: Algorithm changes during the test
- Seasonality: Special events or trends
- Technical Problems: Server failures or crawling issues
- Competitor Activities: New competitors or their changes
Important
Disturbing factors must be considered in result interpretation

Avoid Common Mistakes
001. Insufficient Test Duration
Tests should run for at least 4 weeks to account for seasonal fluctuations and Google updates.
002. Missing Control Group
Without a comparison group, results cannot be clearly attributed to the test measure.
003. Too Many Variables Simultaneously
Simultaneous changes to multiple factors make it impossible to isolate the effect of individual measures.
004. Unclear Success Criteria
Before test start, clear criteria for success or failure must be defined.
