Core Web Vitals

1. Understanding the Three Core Web Vitals Metrics

Largest Contentful Paint (LCP)

LCP measures the time it takes for the largest content element on a web page to become visible to users. This element is often an image, video, or block-level element. A fast LCP is crucial as it ensures that users see meaningful content quickly, reducing bounce rates and keeping users engaged.

To improve LCP, consider the following:

1. Optimize and compress images without compromising quality.
2. Use lazy loading for images and videos to prioritize content above the fold.
3. Upgrade your hosting plan to ensure faster server response times.
4. Don’t use Slideshow
5. Don’t use Any Animation

1. Swap Google Font Display – For Font
2. Async javascript – For Rander Blocking Javascript Resources
3. Autoptimize or Wp Rocket – Minify HTML, CSS, JS Code. 

Procedure* (JS, CSS,& HTML – Javascript options – Optimize Javascript code – Optimize CSS Code – Optimize HTML Code – Save Change & Empty Cache)

  4. Webp Converter for Media – Convert image to Webp (Settings – Webp Converter – Select Image Quality – Regenerate All)

First Input Delay (FID)

FID evaluates the time between a user’s first interaction (clicking a link, tapping a button) and the browser’s response to that interaction. A low FID is essential for providing a responsive and interactive user experience. First Input Delay is Closely related to Total Block Time. If TBT High FID also high.

To enhance FID, follow these tips:

1. Minimize JavaScript execution time by removing unused code and optimizing critical scripts.
2. Use browser caching to reduce the loading time of external scripts.
3. Consider using a content delivery network (CDN) to serve assets from servers closer to users.
4. Reduce Third Party Code.
5. Minimize Main Thread Work.

Cumulative Layout Shift (CLS)

CLS measures the visual stability of a web page by calculating the sum of all unexpected layout shifts that occur during the page’s lifespan. Websites with a high CLS can frustrate users, especially if they accidentally tap on the wrong element due to shifting page elements.

Improve CLS by implementing these practices:

1. Specify image dimensions to prevent unexpected layout changes caused by media loading.
2. Avoid inserting dynamic content above existing elements that may cause layout shifts.
3. Use CSS animations with proper sizing and positioning to avoid sudden movements.

Optimizing Core Web Vitals for Your Website

Now that we’ve explored the three Core Web Vitals metrics, it’s time to take action and optimize your website for better performance. Follow these steps to enhance your website’s user experience and search rankings:

1. Conduct a Core Web Vitals Audit: Use Google’s PageSpeed Insights or other available tools to assess your website’s performance based on Core Web Vitals metrics. Identify areas that require improvement.

2. Optimize Images and Media: Compress images, use modern formats (WebP), and apply lazy loading to prioritize content delivery.

3. Prioritize Critical Resources: Identify and optimize critical resources (CSS, JavaScript) needed for above-the-fold content to load faster.

4. Minimize Third-Party Scripts: Reduce reliance on third-party scripts, or defer their loading to improve FID.

5. Implement Caching: Leverage browser and server caching to speed up subsequent page loads.

6. Upgrade Hosting: Consider upgrading to a faster and more reliable hosting provider.

7. Use CDNs: Utilize content delivery networks to reduce server response times.

8. Monitor and Iterate: Regularly monitor your website’s performance, and make iterative improvements to address any issues that arise.
