Traffic split
Make sure your testing tools are set up correctly, split traffic evenly, and introduce no bias into your experiment data.
Understand how much your conversion rates naturally fluctuate so you can spot real lift when it happens.
Verify that your sensitivity thresholds are properly calibrated to your traffic volume so future tests are accurate and reliable.
Ensure your testing platform and analytics tools are reporting the same numbers before you start experimenting.
Choose your target URL, and our platform will automatically generate an identical clone.
Select the conversion events you want to track and optimize for across both test variations.
Set sample size and test duration to capture representative data.
A successful A/A test should result in no statistical significance. This confirms your environment is stable and any lift in future experiments is real, not technical noise or baseline variance.
If the test reports a "winner," it signals an underlying issue like a tracking bug, bot interference, or sample ratio mismatch. A/A testing helps you catch and fix these issues before they compromise your experiments.

Lock your traffic at an exact 50/50 split, so both versions receive an equal share of visitors.
Our platform randomly assigns visitors to each variation to prevent selection bias and skewed audience distribution.
Rule out platform-specific bugs by checking for significance across browsers, devices, and segments.
Get automatic warnings if your traffic split drifts beyond a 1% margin, indicating sample ratio mismatch.
Receive real-time alerts if our platform detects a "winner" where none should exist.
Our CRO experts audit and validate your entire experimentation setup—from platform integration and tracking accuracy to statistical calibration—so you can scale your testing program with full confidence that every result is reliable.
