What is Page Speed?

Page speed is measured by the time duration it takes a web page for a user to fully load.

Faster page speeds are crucial because they enhance user experience by reducing wait times, and they positively impact SEO rankings, as search engines favor websites that offer quick and efficient user experiences.

What Influences the Page Speed?

Several factors contribute to how quickly a webpage loads, and understanding these can help you optimize your site’s performance.

1. Server Response Time

The period it takes for a server to respond to a user’s request plays a significant role in page speed. Optimizing server performance can reduce delays.

2. File Sizes

Large files, such as high-resolution images and extensive scripts, can slow down page loading times. Compressing files and optimizing images can significantly enhance speed.

3. Browser Caching

Browser caching allows frequently accessed resources to be saved locally on users’ devices, which speeds up repeat visits.

4. Code Efficiency

Clean, efficient code with minimized CSS, JavaScript, and HTML can reduce the time it takes for a browser to process and render a webpage.

5. Content Delivery Network (CDN)

Using a CDN can distribute the load by serving content from the server closest to the user, thereby speeding up page load times.

How Core Web Vitals Affect Page Speed?

Core Web Vitals are a group of distinct aspects that Google considers essential for providing a great user experience on the web. These include:

  • Largest Contentful Paint (LCP): Calculates the time it takes for a page’s primary content to load. An ideal LCP is 2.5 seconds or faster.
  • First Input Delay (FID): Calculates the time between a user’s initial interaction with a page and the browser’s response to that interaction. The optimal FID is less than 100 milliseconds.
  • Cumulative Layout Shift (CLS): Measures a page’s visual stability, which ensures that components do not shift abruptly. An ideal CLS score is under 0.1.
