Diagnosis

Two GA4 page_view events fired during a single page navigation. This commonly happens when GA4 is installed multiple times (for example via gtag.js and Google Tag Manager) or when SPA navigation triggers duplicate page_view events.

Why this matters

Duplicate page_view tracking can inflate traffic and route-level engagement metrics.

Common symptoms
  • • Page views seem too high
  • • Traffic metrics look inflated
  • • Reports do not match expectations
  • • DebugView shows repeated page_view events
Typical causes
  • • GA4 installed via gtag.js and GTM
  • • SPA navigation triggers duplicate page_view
  • • Multiple GTM containers
  • • Automatic page_view enabled + manual page_view
How to fix
  1. 1
    Check whether GA4 is implemented through both gtag.js and GTM.
  2. 2
    Confirm only one config path is sending page_view on each navigation.
  3. 3
    If this is an SPA, verify page_view only fires once per route change.
  4. 4
    Disable automatic page_view if you intentionally send page_view manually.

FAQ
What does this sample scan test?

This sample demonstrates a complete analytics tracking validation scan including duplicate events, missing events, failed requests, JavaScript errors, and configuration consistency checks.

Does this report use real scan data?

Yes. Sample scan pages render real scan findings and evidence, with a light public wrapper for context and navigation.

Why show technical evidence on a public page?

The technical layer makes the findings defensible and useful to implementers, not just readable to marketers or PMs.

Can I run the same scan on my site?

Yes. The public sample is a published example of the same scan structure used for live user reports. Use the scanner landing page to run the same validation on your own site.
