Real User Monitoring vs Lighthouse-Based Testing

Auditzy™ vs GTmetrix

Auditzy™ monitors real-user experiences on your site for captured sessions and page views, with context such as device, network speed, device memory (RAM), operating system, browser, location, page, and configured journey. It also helps brands understand how website speed affects configured conversion funnels. GTmetrix runs Lighthouse-powered browser tests for selected URLs and displays aggregated CrUX field data when eligible.

Short Answer

GTmetrix Tests Selected Pages; Auditzy™ Monitors Production Visitors

A GTmetrix lab report shows how one selected URL performs under configured test conditions and provides technical artifacts for investigating that run. Its CrUX tab can add a 28-day aggregate of eligible Chrome-user experiences, but it does not expose your first-party sessions, page views, or conversion outcomes. Auditzy™ captures real-user experience data directly from your site, reveals variation across production segments, and connects website-speed differences with configured conversion funnels.

Key Differences

What Changes Between Auditzy™ and GTmetrix

01

First-party visitors vs lab and public field data

Auditzy™ monitors captured sessions and page views directly on your site. GTmetrix primarily runs controlled browser tests and supplements eligible reports with aggregated CrUX data from Google.

02

Conversion funnels vs page-test reports

Auditzy™ relates website-speed differences to configured conversion funnels and journey outcomes. GTmetrix reports technical performance for selected URLs rather than your first-party conversion population.

03

Granular segments vs aggregated CrUX

Auditzy™ reveals variation by page, device, network speed, memory, operating system, browser, location, and journey. GTmetrix states that its CrUX view aggregates devices, locations, connections, and Chrome versions.

04

Production impact vs repeatable diagnostics

Auditzy™ shows where performance issues occur across captured traffic and which journeys are affected. GTmetrix helps reproduce page behavior using consistent conditions, waterfalls, video, Lighthouse metrics, and scheduled tests.

Questions, Answered

Auditzy™ vs GTmetrix FAQ

Does GTmetrix provide real-user data?

GTmetrix displays aggregated Chrome UX Report data when a page or origin is eligible. This is public field data from Google, not a first-party collection of your individual production sessions and page views.

Does GTmetrix monitor individual production visitors?

No. Its primary reports come from controlled Lighthouse-powered tests, while its CrUX tab displays aggregated eligible Chrome-user data. It does not expose your individual first-party sessions or page views.

What does Auditzy™ measure that GTmetrix does not?

Auditzy™ monitors captured sessions and page views from actual visitors with context including page, device, network speed, device memory, operating system, browser, location, and configured journey. It also connects website-speed differences with configured conversion funnels.

Can GTmetrix show how website speed affects conversions?

GTmetrix can test and monitor selected URLs, but it does not collect your first-party session-level conversion-funnel outcomes. Auditzy™ is designed to relate real-user website performance to configured conversion journeys.

Why might Auditzy™ and GTmetrix show different performance results?

They use different data sources and time windows. Auditzy™ captures visits across varied production conditions. A GTmetrix lab report reflects its configured test run, while its CrUX section summarizes eligible Chrome-user data over a rolling 28-day period.

When should a team use Auditzy™ or GTmetrix?

Use Auditzy™ to understand real-user performance, affected segments, production reach, and conversion-funnel impact. Use GTmetrix to test selected pages, inspect Lighthouse metrics and waterfalls, and track repeatable lab results. Teams may use both for different stages of diagnosis and validation.
