What are Core Web Vitals?

Google's Core Web Vitals are a set of specific factors that Google considers important in a webpage's overall user experience. They form part of Google's page experience score, which measures how users interact with a web page beyond its pure informational value. Core Web Vitals consist of three elements:

  1. Largest Contentful Paint (LCP): This measures the loading performance of a webpage. To provide a good user experience, Google recommends an LCP of 2.5 seconds or faster.
  2. First Input Delay (FID): This quantifies the interactivity and responsiveness of a webpage. To offer a smooth user experience, pages should have an FID of less than 100 milliseconds.
  3. Cumulative Layout Shift (CLS): This reflects the visual stability of a webpage. Pages should maintain a CLS of less than 0.1 for a pleasant user experience.

Why are Core Web Vitals Important for SEO?

With the introduction of Core Web Vitals, Google is making a clear statement about the importance of user experience in its search algorithm. But why is this important for SEO?

  1. Search Ranking: Google has confirmed that Core Web Vitals are a ranking factor. Websites that don't meet the threshold for good Core Web Vitals may suffer a decrease in their search rankings, while those that do might get a boost.
  2. User Engagement: Speedy, interactive, and stable websites can lead to higher user engagement. Better user experience translates into lower bounce rates and higher time-on-page, both of which are positive signals to Google's algorithm.
  3. Conversion Rates: Improved user experience can also lead to higher conversion rates. A slow, unresponsive, or unstable website is likely to turn visitors away, reducing the likelihood of conversions.

How to Optimize for Core Web Vitals

Given their importance, the next logical question is, "How can I optimize my website for Core Web Vitals?" Here's a step-by-step guide:

1. Measure Your Core Web Vitals: Google has several tools, like PageSpeed Insights, Search Console, and the Chrome User Experience Report, that can help you measure and understand your website's Core Web Vitals.

2. Optimize LCP: Several strategies can help improve your LCP score:

  • Optimize your server response time: Consider using a Content Delivery Network (CDN), optimizing your server software and resources, and implementing caching.
  • Optimize images: Use appropriate image sizes, formats, and compression levels to ensure they load as fast as possible.
  • Minimize render-blocking JavaScript and CSS: By deferring non-critical JavaScript and CSS, you can ensure that the main content loads quickly.

3. Improve FID: For a good FID score, minimize heavy JavaScript execution. Breaking up long tasks, optimizing your page for interaction readiness, and using a web worker can also help.

4. Minimize CLS: Always include size attributes on your images and video elements or reserve the required space with CSS aspect ratio boxes to avoid layout shifts. Additionally, avoid inserting content above existing content unless it's in response to user interaction.


In today's competitive digital landscape, providing a great user experience is essential for SEO and overall business success. By focusing on Google's Core Web Vitals, you can improve your site's user experience, search ranking, and potentially even your conversion rates. As Google's algorithms continue to evolve, keeping user experience at the forefront of your SEO strategy is a sound approach.
