Best Practices for Website Speed Optimization:

1. Reduce the Number of HTTP Requests

http request

One of the most effective ways to speed up your website is by reducing the number of HTTP requests made by the browser. Each request adds overhead in establishing a connection with the web server, especially with HTTP/1.1. Additionally, browsers have a limit on the number of parallel network requests, so excessive requests can lead to blocking and slower loading times.

To optimize this, start by eliminating unnecessary requests. Determine the minimum resources required for your website’s rendering and load only those. Remove any redundant images, JavaScript files, stylesheets, fonts, and unnecessary plugins if you’re using a CMS like WordPress.

Once you have trimmed down the resources, the next step is to optimize the remaining ones. Consider compressing your CSS and JavaScript files. Optimized websites often load all the required CSS and JavaScript in a single request. Monitoring tools like Sematext Experience can help you identify slow-loading resources and HTTP requests for real user monitoring.

2. Switch to HTTP/2


HTTP/2 is an improved protocol over HTTP/1.1, offering several advantages in terms of website performance. One key benefit is the ability to send multiple files simultaneously over the same connection, avoiding the overhead of multiple requests. By switching your website to HTTP/2, you can enhance its loading speed.

The process of migrating to HTTP/2 depends on your hosting provider. Consult their documentation or support to enable HTTP/2 for your website. The transition can significantly reduce the load time by leveraging the protocol’s efficient handling of multiple requests.

3. Optimize Image Sizes

Images often play a crucial role in web design, but if not optimized, they can significantly impact your website’s performance. To ensure faster loading times, it’s essential to consider image size optimization.

Start by evaluating the resolution of your images. Using excessively high-resolution images intended for high-density displays, such as retina screens, can waste bandwidth and slow down loading, especially for users on slower mobile data connections. Implement responsive image techniques, specifying multiple sizes to enable the browser to select the appropriate image based on the screen resolution.

Next, focus on optimizing the file size of your images. Remove any unnecessary metadata or unused color information. Tools like Shopify can assist you in effectively reducing image size without compromising quality. Remember to use the appropriate file type: JPEG for images with lots of colors and PNG for simpler graphics.

4. Use a Content Delivery Network (CDN)


Utilizing a Content Delivery Network (CDN) is a smart choice for optimizing the delivery of static files on your website. CDNs are services designed specifically for this purpose, enhancing the performance of CSS, images, fonts, and JavaScript files by serving them from geographically distributed servers. By leveraging CDNs, the server closest to each visitor serves the files, ensuring consistent load times regardless of the user’s location. This approach is especially beneficial when serving static files from your own servers, as load times can increase for users far away from the server.

Setting up a CDN is typically straightforward. Explore different CDN providers and follow their documentation to integrate the service with your website. Tools like Sematext Experience enable you to monitor CDN-hosted files’ performance, helping you determine the effectiveness of outsourcing this part of your infrastructure.

5. Write Mobile-First Code

With the increasing dominance of mobile devices, it’s crucial to prioritize mobile optimization in your web development process. Instead of developing and optimizing your website primarily for desktop devices, adopt a mobile-first approach.

To ensure an optimized experience for mobile users, consider using a Real User Monitoring (RUM) solution like Sematext Experience or analytics tools like Google Analytics to understand your user base and their devices. By testing and developing your website with mobile devices or emulators, you can create a user experience that is inherently optimized for mobile screens and slower network connections.

Responsive web design plays a significant role in mobile optimization. It allows your website to adapt its layout and content based on the screen size, ensuring readability and usability across a variety of devices. Implement responsive design techniques using CSS media queries to achieve this flexibility. Regularly test your website on various mobile devices and simulate different network conditions to identify areas for improvement. Tools like Google’s Mobile-Friendly Test can help you assess your website’s mobile performance and provide suggestions for optimization.

Check out Nestify plans here.

8. Implement Gzip Compression:


Enable gzip compression on your web server to reduce the size of HTTP responses for compatible file types. Gzip compression compresses files before sending them to the browser, reducing bandwidth usage and improving load times. By configuring your server to compress files such as HTML, CSS, and JavaScript, you can enhance website performance and provide faster page rendering for visitors.

9. Minify and Combine CSS, JavaScript, and HTML Files:


Minification involves removing unnecessary characters, such as whitespace and comments, from CSS, JavaScript, and HTML files. This reduces the file sizes and improves load times. Additionally, combine multiple CSS and JavaScript files into single bundles to minimize the number of network requests required to load these resources. This optimization technique reduces latency and enhances overall website performance.

10. Load JavaScript Asynchronously:


By using the “async” attribute on <script> tags, you can load JavaScript files asynchronously. This means that the browser can continue rendering the page without waiting for the JavaScript file to finish loading. Asynchronous loading improves the perceived performance of the website, as the page becomes usable even before all JavaScript files are fully loaded.

11. Consider Using Prefetch, Preconnect, and Prerender Techniques:


Leverage techniques like DNS prefetching, TCP preconnect, prefetching, and prerendering to optimize resource loading and improve perceived performance. DNS prefetching allows the browser to resolve DNS requests in advance, preconnect establishes early connections to necessary domains, prefetching loads resources in the background, and prerendering anticipates user actions and preloads relevant pages. By implementing these techniques, you can reduce latency and provide a smoother browsing experience.

12. Reduce the Number of Plugins:

Evaluate the plugins installed on your website and remove any unnecessary ones. Each plugin can add additional CSS, JavaScript, and server processing overhead, impacting website performance. Keep only the essential plugins that provide significant functionality and consider alternative approaches for features that can be achieved without plugins. Regularly review and update your plugin selection to ensure optimal performance.

13. Use Website Caching:

web caching

Enable browser caching by setting appropriate cache headers on your server. Caching allows the browser to store static files locally, such as images, CSS, and JavaScript, after the first visit. When the visitor returns, the browser can retrieve these files from the cache instead of making requests to the server, reducing server workload and improving load times. Implementing efficient caching mechanisms can significantly enhance website performance, particularly for returning visitors.

14. Adopt Cloud-Based Website Monitoring:
