SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Helps support and analytics engineers rapidly determine root causes for missing or inaccurate web analytics in PostHog by guiding a systematic investigation of event ingestion, SDK setup, session attribution, and discrepancies with other analytics tools.

Core Features & Use Cases

  • Event ingestion checks: Verify presence and volume of $pageview, $pageleave, and autocapture events to detect SDK or capture failures.
  • Installation and SPA diagnosis: Identify common SDK misconfigurations, router integration gaps, and framework-specific client navigation issues.
  • Attribution and accuracy analysis: Troubleshoot missing UTM data, channel misattribution, ad blocker losses, and session or bounce-rate anomalies, and compare results with Google Analytics.
  • Search for known bugs: Run targeted GitHub issue searches and consult live documentation to surface product bugs or required SDK versions.
  • Use case: Triage a ticket reporting zero pageviews or inconsistent traffic versus GA and produce a prioritized checklist and recommended fixes.

Quick Start

Use the posthog-web-analytics-diagnosis workflow to triage a ticket about missing pageviews and produce a concise diagnostic report with likely causes and recommended remediations.

How do I troubleshoot missing UTM parameters and channel attribution in PostHog?▼

Troubleshoot missing UTM parameters and channel attribution in PostHog by analyzing session accuracy, checking for channel misattribution, and verifying that attribution data is correctly captured during event ingestion.

Why does PostHog show different traffic numbers compared to Google Analytics?▼

PostHog shows different traffic numbers compared to Google Analytics due to discrepancies in event ingestion, ad blocker losses, and session attribution logic. Investigate these areas to reconcile the differences during support investigations.

How do I find known bugs causing PostHog bounce rate anomalies?▼
