Anomaly digests with spam detection

Statistical spike and drop detection across traffic sources, devices, countries, pages, and events — every finding ranked by business impact, so the change that matters most is always at the top. Daily or weekly, sent only when something is statistically significant. Zero-data alerts run daily.

  • Flags likely spam clusters — fake referrals and bot patterns grouped and labeled, not scattered across ten line items
  • Compares 7/30/90-day windows against the prior period
  • Watch all events or just the ones you care about

Zero-data alerts

Broken tracking is silent — GA4 never tells you an event stopped firing. Every morning at 6 AM (your property's timezone) we check yesterday for events and pages that normally get traffic but flatlined.

  • Catches tag, consent, and release regressions fast
  • Baselines from the prior 7 days — no thresholds to tune
  • Alerts only when something flatlines, never “all clear” spam

Questions, answered

What access do you need to my Google Analytics?+

Read-only. Signing in with Google is both your login and your GA4 connection — we request read-only Analytics scopes and can never change anything in your property. Credentials are encrypted and you can delete them any time.

What counts as a monitored property?+

A distinct GA4 property with either alert type turned on. Anomaly digests and zero-data alerts on the same property count as one.

Is there a free plan?+

Yes — monitor 1 GA4 property free forever. Upgrade when you need more properties. No card required to start.

How do Slack alerts work?+

Connect Slack with one click from your account or settings page, or paste an incoming-webhook URL for the channel you want. Email alerts go to your sign-in address. You can use either or both, per property.

How does spam detection work?+

The anomaly digest groups suspicious traffic — like a surge tied to one referral source or screen resolution with near-zero engagement — and labels it as a likely spam cluster. You see one clear callout instead of chasing ten confusing line items, and you know not to celebrate a fake traffic spike.

Will I get an alert every day?+

Only when something is actually wrong or unusual. Quiet days send nothing — no noise, no “everything is fine” emails.

Can I cancel anytime?+

Yes — self-serve from the billing portal, effective at the end of your billing period. Your alert configuration is kept in case you come back.
