How it works
Spot traffic drops and spikes before they escalate.
Link your GSC property. The tool analyses your historical data to establish normal patterns for traffic, impressions, and rankings.
As new GSC data comes in, the detector compares it against your baseline. Deviations beyond the normal variance threshold are flagged as anomalies.
Click any anomaly to see the affected pages and queries. Drill into whether it's a ranking change, indexing issue, or seasonal pattern.
Why use it
Spot traffic drops and spikes before they escalate.
Most SEOs notice traffic problems in their monthly review. The Anomaly Detector flags issues as they emerge so you can act while there's still time to recover quickly.
Day-to-day fluctuation is normal. The detector uses statistical thresholds calibrated to your site's own variance, so you're not chasing false alarms.
Monitors at the site level, page level, and query level simultaneously. A drop on a single product page doesn't hide in aggregate numbers.
Sudden spikes are flagged as well - useful for understanding what's working so you can replicate it, and for verifying that a new piece of content is picking up traction.
Each anomaly comes with the relevant data breakdown - which queries changed, which pages are affected, whether position or CTR drove it - so you're not starting your investigation from zero.
