Tips to Increase Website Speed: How to Speed Up Websites

Why Does Website Speed Matter?

In today's digital age, speed is essential. According to research, people will abandon a slow-loading website after waiting between 0.3 and 3 seconds. Websites that load quickly have fewer bounce rates, higher conversion rates, and better ranks in organic search results, resulting in a better overall user experience.

Factors affecting site speed

A variety of issues can cause your website to slow down:

• Heavy CSS and JavaScript use
• Poor server/hosting plan.
• Large image sizes.
• Not using the browser cache.
• Too many widgets and plugins.
• Hotlinking pictures and other materials from sluggish servers.
• High traffic volume.
• Older browsers
• Slow network connections, particularly for mobile devices

Measuring Website Performance

Before you make any changes, assess your website's existing performance. This allows you to compare the outcomes before and after optimizations. The key metrics to monitor are:

• Largest Contentful Paint (LCP): Determines how rapidly the largest element on a page loads.

• First Input Delay (FID): Determines how long it takes a page to respond to user input.

• Cumulative Layout Shift (CLS): Assesses the visual stability of a page's parts.

These metrics can be measured with tools such as Google Lighthouse and Cloudflare Observatory. Aim for this:

• LCP: < 2500ms (good); > 4000ms (poor).
• FID: < 100ms (good); > 300ms (poor).
• CLS: ≤ 0.1 (good); > 0.25 (poor).

Best Practices for Improving Website Performance

1. Optimize images.

Large graphics might substantially slow down your website. Reduce the resolution, dimensions, and file size. Use the proper file types: JPEG for photos and PNG for minimal graphics.

2. Reduce HTTP requests.

Each webpage usually necessitates several HTTP requests for pictures, scripts, and CSS files. Reduce the quantity of these queries to speed up your site. Files should be combined and compressed whenever possible.

3. Enable Browser HTTP Caching.

Utilize browser caching to save static files locally, avoiding the need to re-download them on future visits. This can be accomplished via HTTP response headers.

4. Minify CSS and JavaScript.

Remove any unneeded characters from your code without harming its functionality. Minified files are smaller and load more quickly.

5. Limit external scripts.

Reduce your reliance on external scripts, which might slow down page loading. Use only the essential external resources, and consider loading scripts asynchronously.

6. Limit Redirect Usage

Redirects increase load time. Reduce their utilization and constantly analyze your website to remove any superfluous redirects.

7. Use a Content Delivery Network (CDN)

CDNs store static files in many places globally, allowing for speedier delivery to users based on their location.

8. Select a Reliable Hosting Plan.

Choose a hosting plan that meets your needs. Shared hosting is cost-effective yet may be sluggish. Consider VPS, dedicated, or serverless hosting for improved performance.

9. Implement Gzip compression.

Set up Gzip compression on your server to reduce the size of your HTML, CSS, and JavaScript files.

10. Create mobile-first code.

Optimize your site for mobile devices first, then improve it for desktop users. This improves performance on mobile devices, which frequently have poor connections.

11. Use Prefetch, Preconnect, and Prerender.

These approaches assist the browser predict the resources it will use next, decreasing load times:

• DNS Prefetch: Resolves domain names before the browser requests them.
• TCP Preconnect: Creates connections before they are needed.
• Prefetching resources means downloading them before they are requested.
• Prerender: Preloads complete pages that the user is likely to visit next.

Monitoring and Continuous Improvement.

Use cloud-based monitoring tools to continuously measure and enhance your website's performance. Synthetic monitoring and real-user monitoring (RUM) provide useful information about your website's performance and user experience.

Implementing these recommended practices will greatly enhance your website's speed, resulting in a better user experience and higher search engine rankings. Regularly analyze your site's performance to identify areas for improvement.
