10 SEO Trends for 2023: 9. Focusing on Core Web Vitals

Search engine optimization (SEO) is a constantly evolving field, and website owners must stay up-to-date with the latest trends and best practices to ensure that their sites rank well in search results. In 2023, one trend that is expected to be a major focus in SEO is the optimization of core web vitals.

What are Core Web Vitals?

Core web vitals are a set of metrics that measure the user experience of a website. They are designed to help website owners understand how users perceive their website’s speed, interactivity, and visual stability. Google has identified three specific metrics as core web vitals:

  1. Largest Contentful Paint (LCP): measures the loading speed of a website’s main content. This metric should be less than 2.5 seconds.
  2. First Input Delay (FID): measures the interactivity of a website. This metric should be less than 100 milliseconds.
  3. Cumulative Layout Shift (CLS): measures the visual stability of a website. This metric should be less than 0.1.

Why do Core Web Vitals Matter for SEO?

Google has always prioritized user experience in its search algorithm. In May 2021, Google officially announced that it would use core web vitals as a ranking factor. This means that websites with better core web vitals are more likely to rank higher in search results.

In addition to improving search engine rankings, optimizing core web vitals can also lead to improvements in user engagement and conversions. Users are more likely to stay on a website that loads quickly and functions smoothly, and they are more likely to complete a purchase or take some other desired action if the website is easy to use.

How to Optimize Your Website for Core Web Vitals?

  1. Improve Page Speed: To improve LCP, website owners can optimize images and videos, minify code, and use a content delivery network (CDN) to reduce server response times.
  2. Optimize Interactivity: To improve FID, website owners can reduce third-party scripts, optimize JavaScript and CSS, and use a faster web host.
  3. Enhance Visual Stability: To improve CLS, website owners can use appropriate image and video sizes, reserve space for dynamic content, and avoid using intrusive pop-ups.
  4. Use Tools to Measure and Monitor Core Web Vitals: Google provides several tools to measure core web vitals, including PageSpeed Insights, Lighthouse, and Search Console. Website owners can use these tools to identify areas for improvement and track progress over time.
