Understanding the Impact of Core Web Vitals on Your SEO in 2023

As we navigate the digital landscape in 2023, the importance of Search Engine Optimisation (SEO) continues to grow. Businesses, both large and small, are battling for the top spots on Google’s search results, and the competition is fierce. At Promovo, we’re here to guide you through these changes, starting with a crucial aspect of SEO: Core Web Vitals.

What are Core Web Vitals?

Core Web Vitals are a set of metrics Google uses to measure the speed, responsiveness, and visual stability of a webpage. They include:

  • Largest Contentful Paint (LCP): This 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): This measures interactivity. To provide a good user experience, pages should have a FID of fewer than 100 milliseconds.

  • Cumulative Layout Shift (CLS): This measures visual stability. To provide a good user experience, pages should maintain a CLS of fewer than 0.1.

Why Core Web Vitals Matter for SEO

In today’s digital landscape, a user-friendly experience is not just preferred – it’s expected. Google has recognised this and has started to factor in Core Web Vitals into their ranking algorithm. Websites with better scores are likely to rank higher in search results, leading to increased visibility and higher traffic.

How to Measure Core Web Vitals

Google offers several tools to measure Core Web Vitals, including Google Search Console and PageSpeed Insights. These tools provide insights into how your website performs and offer suggestions for improvement.

Improving Your Core Web Vitals

Optimising your Core Web Vitals is a technical process, but here are a few general tips:

  • Optimise images: Compress your images and use the right format. This can drastically reduce LCP.

  • Minimise JavaScript: Excessive JavaScript can increase your FID. Minimise or defer non-critical JavaScript.

  • Improve server response times: Your server's response time can significantly impact your LCP. Use a Content Delivery Network (CDN) and optimise your server to improve response times.
