Anomaly Alerts
Never miss a significant change in your analytics. Get alerted when metrics deviate from their expected patterns.
What are Anomaly Alerts?
Anomaly Alerts use statistical analysis to continuously monitor your GA4 metrics. When a metric deviates significantly from its recent trend, we flag it as an anomaly and notify you. This means you catch traffic spikes, revenue drops, or engagement changes before they become problems.
How It Works
Modified Z-Score with Median Absolute Deviation
We analyze each metric over a 28-day rolling window using the modified Z-score method. This approach is robust to outliers because it uses the median and Median Absolute Deviation (MAD) instead of mean and standard deviation. When today's value falls outside expected bounds, an alert is triggered with a severity level based on the Z-score magnitude.
