How often does QueryWatch check for traffic drops?

QueryWatch Pro checks your Search Console properties for traffic changes every six hours. The check runs on the developer’s own relay server in Germany, not on your phone, and only for Pro users who have turned push alerts on. The free tier has no alerts.

What is compared each time?

The relay takes the latest complete day of Search Console data and compares it with the same weekday over the previous four weeks. A Tuesday is compared with earlier Tuesdays, so the normal weekly rhythm of a site does not trigger a false alarm.

An alert fires at a 30 percent change or two standard deviations, whichever you set. Both thresholds are adjustable per property. QueryWatch sends at most one notification per property per day, and each alert stores an evidence snapshot of what the check saw.

Why every six hours and not instantly?

Search Console data is itself days behind, and the “latest complete day” is the newest day Google has finished reporting. Checking more often than Google updates would add noise, not speed. See why Search Console data is days behind for the detail.

What leaves your phone for alerts to work?

A credential leaves the phone only if push alerts are turned on. Without alerts, the iPhone refresh token stays in the Keychain, and on Android Google Play services hold the grant. More in where your Google token goes.

Where can I read more?

The alerts page shows what each alert looks like, and anatomy of a traffic alert walks through one. QueryWatch is independent and not affiliated with Google.
