Data problems — a tracking pixel breaking, a checkout error, a sudden traffic spike, or a conversion rate crash — often go undetected for days. BigQuery Scheduled Queries can run automatic health checks on your key metrics, comparing each day's data to expected ranges and alerting your team via email or Slack when something looks wrong. We build anomaly detection queries for your most important metrics, so you know about problems before your clients or leadership do.

Frequently Asked Questions

Scheduled queries run daily, comparing current day metrics to historical averages and expected ranges. If a metric falls outside the expected range, a Cloud Function sends an alert to Slack or email.
Conversion rate, daily order count, daily revenue, key event counts (Add to Cart, Purchase), and tracking data volume (to catch pixel fires stopping). We recommend starting with 5–8 most critical metrics.
By analysing historical metric variance and setting thresholds based on statistically significant deviations (e.g., alert when a metric is more than 2 standard deviations from its 30-day mean).
Yes — by comparing daily event counts to expected levels, a significant drop in a specific event (e.g., Purchase events drop to zero) triggers an immediate alert.
BigQuery allows more sophisticated detection logic and can monitor any metric in your data warehouse — not just GA4 metrics. For complex multi-source monitoring, BigQuery is significantly more powerful.
