Engine Calibration Benchmark
We claim our engine scores match Google PageSpeed Insights. To prove it, we built a calibration harness that audits a fixed corpus of 50 real-world sites and publishes the variance.
Pass Rate (≤5 pts)
96.0%
48 out of 50 sites matched PSI within the 5-point variance limit.
Median Drift
±2 pts
The median difference between ScanoraAI's mobile score and Google's raw mobile score.
Outliers
2
Sites exceeding 5-point drift, usually caused by heavy A/B testing or transient CDNs.
Score Variance Distribution
0 - 2 points

Methodology: This calibration runs locally during our CI pipeline. We fire simultaneous, uncached requests to our own analysis engine and the official Google PageSpeed Insights REST API. We capture the mobile performance score from both, diff them, and plot the variance above.
