Today, connection speeds are faster. Most resources are compressed by default and many plugins handle image compression, cache deployment, etc. Google’s quest for a faster web persists. PageSpeed Insights (PSI) is still live on web.dev, serving as the best tool to evaluate individual page loads. While many feel that PSI ratings are unnecessarily punitive, it’s still the closest we can get to how Google might weigh and rank sites via page speed signals. To pass the latest iteration of Google’s page speed test, you’ll need to satisfy the Core Web Vitals Assessment. Understanding the Core of metrics integrated into the broader page experience search signals introduced in 2021.

Each metric “represents a distinct facet of the user experience, is measurable in the field, and DB to Data the real-world experience of a critical user-centric outcome,” according to Google. The current set of Core Web Vitals metrics include: First Contentful Paint First Input Delay (to be replaced by Interaction to Next Paint) Interaction to Next Paint Time to First Byte Largest Contentful Paint Cumulative Layout Shift Web.dev explains how each metric works as follows.



First Contentful Paint (FCP) “The First Contentful Paint (FCP) metric measures the time from when the page starts loading to when any part of the page’s content is rendered on the screen. For this metric, “content” refers to text, images (including background images), <svg> elements, or non-white <canvas> elements.” What this means for technical SEOs FCP is fairly easy to understand. As a webpage loads, certain elements arrive (or “are painted”) before others. In this context, “painting” means on-screen rendering. Once any part of the page has been rendered – let’s say the main nav bar loads in before other elements – the FCP will be logged at that point. Think of it as how quickly the page begins visibly loading for users.
