There can be several reasons why most of your URLs are failing the Core Web Vitals metrics in Google Search Console. Core Web Vitals are a set of performance metrics that measure the user experience of your website, focusing on key factors like page loading speed, interactivity, and visual stability. Failing these metrics can have a negative impact on your search engine rankings and user engagement. Here are some possible reasons why your URLs may be failing:

  1. Page size and content: Large page sizes with heavy media content such as images, videos, or scripts can significantly impact the loading speed of your pages. Optimize your content by compressing images, minifying scripts, and leveraging browser caching to improve loading times.

  2. Server response time: Slow server response times can cause delays in rendering your website's content. Check for any issues with your server configuration or hosting provider and ensure that it is capable of handling the expected traffic.

  3. Render-blocking resources: Render-blocking resources such as JavaScript and CSS files can prevent the browser from rendering the page until the scripts are fully loaded. Optimize your code by removing or deferring unnecessary scripts, and ensure that critical resources are loaded asynchronously to improve page interactivity.

  4. Cumulative Layout Shift (CLS): CLS measures the visual stability of your pages by quantifying how elements move around as the page loads. Unexpected shifts in content, such as ads, images, or dynamic elements, can negatively impact this metric. Avoid placing ads in locations that may cause layout shifts, specify dimensions for media elements, and use proper placeholders to prevent visual instability.

  5. Third-party scripts and plugins: Third-party scripts and plugins can introduce additional performance bottlenecks to your website. Evaluate the necessity and impact of each third-party element, and consider removing or optimizing them to improve page performance.

  6. Mobile optimization: Mobile optimization is crucial for Core Web Vitals, as Google puts a strong emphasis on mobile-first indexing and user experience. Make sure your website is responsive and uses mobile-friendly design practices, such as touch-friendly buttons and font sizes that are easy to read on mobile devices.

To address these issues and improve the Core Web Vitals metrics for your URLs, consider implementing the following best practices:

  • Use a content delivery network (CDN) to optimize the delivery of your website content.
  • Enable browser caching to reduce the amount of data that needs to be downloaded on subsequent visits.
  • Optimize images and use modern image formats like WebP to reduce file sizes without sacrificing quality.
  • Minify and compress CSS and JavaScript files to reduce their file sizes.
  • Load critical CSS inline and asynchronously load non-critical CSS to prevent render-blocking.
  • Prioritize and optimize above-the-fold content to ensure a fast first paint.
  • Lazy load images and videos to improve page load times.
  • Monitor your website's performance using tools like Google PageSpeed Insights or WebPageTest to identify areas for improvement.

By addressing these issues and implementing performance optimization techniques, you can improve the Core Web Vitals metrics for your URLs and enhance the user experience of your website, leading to better search engine rankings and increased user engagement.
