Optimizing WordPress for Google Core Web Vitals
By: Austin Ginder
What are Google's core web vitals?
Why is everyone talking about core web vitals?
"Google will be incorporating Core Web Vitals into its ranking algorithms from May 2021, meaning that your better-performing pages will get a ranking boost, while poorly-performing pages may see a drop in positions."
Core web vitals deal with how preformat your code is, not your server
"To put it simply, while the amount of code will always matter for performance, you also now have to consider how your website loads the code."
Largest Contentful Paint (LCP) measures loading performance. To provide a good user experience, LCP should occur within 2.5 seconds of when the 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.
Where to start
Pagespeed is not web host performance
- Fast web hosting will not solve pagespeed issues
- Same website, same web host can have vastly different scores with different themes and plugins.
How to improve?
- Existing themes: WP Rocket, Jetpack Image CDN, How to Speed Up Your WordPress Site (Ultimate 2021 Guide)
- Switch to a already preformat theme like Blocksy.
