How to Improve Your Website Speed: A Comprehensive Guide for Business Owners

Website speed is crucial for user experience (by things loading fast on 4G, 5G, and Wifi) and search engine optimization (SEO). A slow-loading website can lead to high bounce rates and lost revenue. Fortunately, tools like Google PageSpeed Insights provide valuable insights into your website's performance and offer actionable recommendations for improvement. In this guide, we will explore various categories of site speed improvements based on key metrics from Google PageSpeed Insights, helping you enhance your website's speed effectively.

Understanding Google PageSpeed Insights

Google PageSpeed Insights analyzes your website's performance on both mobile and desktop devices, providing a score between 0 and 100. A higher score indicates better performance. The tool evaluates several metrics, includingLargest Contentful Paint (LCP),Cumulative Layout Shift (CLS), andFirst Input Delay (FID), which are essential components of Google's Core Web Vitals.

Key Metrics to Focus On

Largest Contentful Paint (LCP): Measures loading performance. Ideally, LCP should occur within 2.5 seconds of the page starting to load.
Cumulative Layout Shift (CLS): Measures visual stability. A CLS score of less than 0.1 is considered good.
First Input Delay (FID): Measures interactivity. A FID of less than 100 milliseconds is ideal.

Categories of Site Speed Improvements

1. Optimize Loading Performance

Largest Contentful Paint (LCP)is a critical metric that reflects how quickly the main content of your page loads. If your LCP is at 3,610 ms, here are some strategies to improve it:

Optimize Images: Compress images and use modern formats like WebP to reduce load times.
Minimize Server Response Time: Ensure your server responds quickly to requests. Aim for a response time of under 200 ms.
Use a Content Delivery Network (CDN): CDNs distribute your content across multiple servers worldwide, reducing latency.

2. Reduce Unused JavaScript

Your report indicates potential savings of 133 KiB by reducing unused JavaScript. Here’s how to tackle this:

Audit Your JavaScript: Identify and remove any scripts that are not necessary for your page.
Code Splitting: Break your JavaScript into smaller chunks that can be loaded on demand rather than all at once.
Defer Non-Critical JavaScript: Use the defer attribute to load scripts after the main content has loaded.

3. Serve Static Assets with an Efficient Cache Policy

With 54 resources found that could benefit from caching, implementing an effective caching strategy is essential:

Leverage Browser Caching: Set expiration dates for static resources to reduce load times for returning visitors.
Use Cache-Control Headers: Specify how long browsers should cache your resources.

4. Remove Duplicate Modules in JavaScript Bundles

Your report suggests potential savings of 33 KiB by removing duplicate modules. To address this:

Analyze Your Bundles: Use tools like Webpack Bundle Analyzer to identify and eliminate duplicate modules.
Consolidate Libraries: If you’re using multiple libraries that serve similar purposes, consider consolidating them into a single library.

5. Avoid Serving Legacy JavaScript to Modern Browsers

With potential savings of 5 KiB, ensure that your website serves only the necessary JavaScript for modern browsers:

Use Feature Detection: Serve different scripts based on the capabilities of the user's browser.
Transpile Modern JavaScript: Use tools like Babel to convert modern JavaScript into a format compatible with older browsers.

6. Minimize Layout Shifts

Your report indicates one layout shift, which can negatively impact user experience. To minimize layout shifts:

Specify Dimensions for Images and Videos: Always set width and height attributes to prevent content from shifting during loading.
Avoid Inserting Content Above Existing Content: Ensure that new content is added below existing content to maintain layout stability.

7. Optimize Server Response Time

With an initial server response time of 70 ms, you’re on the right track, but there’s always room for improvement:

Choose a Reliable Hosting Provider: Ensure your hosting provider offers fast server response times.
Optimize Your Database: Regularly clean up your database and optimize queries to improve performance.

8. Avoid Enormous Network Payloads

Your report indicates a total size of 726 KiB, which can slow down loading times. To reduce payload size:

Minify CSS and JavaScript: Remove unnecessary characters from your code to reduce file sizes.
Optimize Fonts: Limit the number of font weights and styles you use to decrease load times.

9. Minimize DOM Size

With 190 elements in your DOM, a large DOM can lead to performance issues. To minimize DOM size:

Reduce the Number of Elements: Simplify your HTML structure by removing unnecessary elements.
Use CSS for Styling: Avoid using excessive inline styles and instead use CSS classes.

10. Avoid Chaining Critical Requests

Your report shows five chains found, which can delay loading times. To avoid chaining:

Prioritize Critical Resources: Load essential resources first to ensure that the main content is displayed quickly.
Use Preload: Use the <link rel="preload"> tag to load critical resources early.

11. Optimize JavaScript Execution Time

With a JavaScript execution time of 0.2 seconds, you’re doing well, but consider these tips to further optimize:

Reduce JavaScript Complexity: Simplify your scripts to reduce execution time.
Use Web Workers: Offload heavy computations to Web Workers to keep the main thread responsive.

12. Minimize Third-Party Usage

Your report indicates that third-party code blocked the main thread for 0 ms, which is excellent. However, it’s essential to keep third-party scripts to a minimum:

Limit Third-Party Scripts: Only use essential third-party scripts to reduce potential performance bottlenecks.
Load Third-Party Scripts Asynchronously: Use the async attribute to load third-party scripts without blocking the main thread.

Improving your website's speed is not just about enhancing user experience; it also plays a significant role in your SEO efforts.
