Measuring and Improving Site Performance With Core Web Vitals

Since the dawn of the Internet, improvements to website performance have mainly been focused on speed. 

While speed is certainly important, today’s definition of website performance should also include an emphasis on the overall end-user or page experience encountered by a site visitor.

With the rollout of Google’s page experience update, which amplifies Core Web Vitals as ranking factors in search, your website’s position in the world’s most widely-used search results is now directly tied to a more user-centric definition of performance. 

This ebook, which was co-authored with Google and 10up, a WP Engine Agency Partner,  explains why website performance matters more than ever, with specific steps site owners and developers can take to measure and improve website performance using Core Web Vitals.

Why Website Performance Matters

Beyond the importance of search engine rankings, building high-performing sites with a focus on page experience affects that crucial moment when a user decides to further engage with you, either by consuming additional content or making a purchase. 

Speed is important here, as fast-loading sites prevent users from exiting a page or abandoning a shopping cart. However,  in order to provide an exceptional page experience for each and every user, performance should also include additional factors aimed at creating visually stable websites that are responsive on any device.

Core Web Vitals offer a framework for creating sites that check all of these boxes. For site owners and developers, this larger view of performance must be front and center in order to create new and innovative experiences that engage users while increasing business-driven metrics.

Measuring Page Experience

Optimizing for page experience is key to the long-term success of any site. Getting it right requires appropriate focus on the right areas as well as ongoing attention and investment. 

Core Web Vitals have been introduced with this in mind, and represent a larger effort to provide unified guidance for quality signals that are essential to delivering a great page experience. 

While the list is set to evolve over time, Core Web Vitals currently measure page experience using the following three metrics: 

List of Google's Core Web Vitals
  • Largest Contentful Paint (LCP): measures loading performance. To provide a good user experience, LCP should occur within 2.5 seconds of when a page first starts loading.
  • First Input Delay (FID): measures interactivity. To provide a good user experience, pages should have a FID of less than 100 milliseconds.
  • Cumulative Layout Shift (CLS): measures visual stability. To provide a good user experience, pages should maintain a CLS of less than 0.1.
