What is Real User Monitoring?

RUM captures performance data for 100% of real traffic via a lightweight tag. How it works, how it differs from synthetic monitoring, and its benefits.

Setting up RUM

Add the RUM JavaScript tag to your site's pages manually or with Google Tag Manager, and check GDPR cookie consent requirements for your country.

Understanding RUM results

Explore RUM data by tab: live view, most visited pages, geography, browsers, and digital sobriety, and filter results with percentiles such as the 75th.

RUM optimization recommendations

Access per-URL optimization audits for your top 10 RUM pages, understand gaps in recommendations, and compare audits to measure the impact of your changes.

Troubleshooting RUM

Fix missing RUM data when a strict Content Security Policy blocks the tag, by adding the Experience Monitoring domains to your CSP directives.
