• . GA4 Site Speed Report

    Posted by Leo on 28 May 2023 at 2:09 am

    “Hey, I’m struggling to find the Site Speed report from GA3 in GA4. I’ve tried to make a new report but couldn’t find a similar metric. I’ve even checked existing reports and experimented in the explore section. Any ideas?”

    Sorry mate, Google Analytics 4 (GA4) doesn’t have built-in tools the way GA3 does for tracking site speed. You’re going to have to DIY this one – you’ll need to generate your own data using custom metrics on the page_view event and create a tailor-made report.

    They’ve got this interface called PerformanceNavigationTiming with loads of timing information you could use. Have a look. [PerformanceNavigationTiming] (https://developer.mozilla.org/en-US/docs/Web/API/PerformanceNavigationTiming)

    The Core Web Vitals include Largest Contentful Paint (LCP), which is about page load speed. Google Chrome’s developed a library that might come in handy – [web-vitals](https://github.com/GoogleChrome/web-vitals)

    In fact, there’s loads of write-ups online about nailing the Core Web Vitals in GA4, exporting the data to BigQuery, and then pulling up reports in Looker Studio. I’ve even chipped in with my two cents 😁. So, keep experimenting, you’ll figure it out!

    Page speed metrics from Universal Analytics (GA3) are not directly transferred into Google Analytics 4 (GA4) because there are substantial changes in how GA4 measures user behavior. However, Google suggests using Google’s PageSpeed Insights tool or Chrome User Experience Report for similar functionality. In addition, engagement and retention metrics in GA4 provide insights into how site speed and performance might be affecting the user experience. So if you want to measure site speed in GA4, you can use these suggested tools and also check out the new GA4 metrics.
