PSI is a tool that reports field data from CrUX and field lab from Lighthouse for a given page. Since the data CrUX provides is a rolling average over the previous 28 days, it's not an ideal tool during development, as it will take a fair amount of time for improvements to be reflected in the CrUX dataset. If this is the case for you, you'll need to gather your own field data to understand how your website performs in the field, as CrUX won't be an option. Websites that don't receive enough traffic are not represented in the CrUX dataset. If you currently don't gather any field data for your website, CrUX is especially valuable-provided your website is represented in its dataset. Though CrUX represents a subset of Chrome users, it's helpful to compare your website's field data to see how it aligns with its CrUX data. When to use CrUX #Įven if you gather your own field data, CrUX is still useful. However, the CrUX API can provide field data at the URL level, provided a URL has enough samples in the CrUX dataset. It also presents Core Web Vitals for websites with sufficient traffic, but only at the origin level. Chrome User Experience Report (CrUX) #ĬrUX is a BigQuery dataset of field data gathered from a segment of real Google Chrome users from millions of websites. While such simulations of slower network and device conditions often help surface user experience problems better than native network and device conditions, they're just a single slice of the large variety in network conditions and device capabilities across a website's entire user base.Īs you continue, understand that it's not necessary for you to use all of the tools in this guide-only those that you believe will help you in improving your website's Core Web Vitals. While lab tools are invaluable, the data they provide isn't always predictive of how a website performs for real users.įor example, Lighthouse runs tests with simulated throttling in a simulated desktop or mobile environment. Collect your own field data if possible # Where it ends may depend on which of Google's tools you'll find useful in diagnosing and fixing user experience problems. Field data is also known as Real User Monitoring (RUM).Ī workflow for improving Core Web Vitals for your website will be explored in this guide, but where that workflow begins depends on whether you're collecting your own field data.
