Web Performance Optimization: 5 Tips for Speeding Up Your Website
Published at July 18, 2023

Website speed plays a crucial role in the world of websites game. To meet these demands, web performance optimization (WPO) is essential.  

Users expect fast-loading websites, and search engines prioritise sites that offer a seamless browsing experience. 

The performance of a website sets the initial impression for any online business. The first moments when users arrive on your site can determine whether they will convert or not.

For e-commerce businesses, understanding the importance of optimal web performance is crucial. A sluggish website can lead to customer frustration and missed sales opportunities.

But first thing first, let’s explore why it is important for your website.

The Matters of Web Performance 

A slow-loading or non-performant website can have detrimental effects on customer experiences and conversion rates. 

According to Statista, the number of online shoppers reached 2.14 billion by the close of 2021. However, only a mere 2.17% of all online visits resulted in successful transactions.

This statistic highlights the importance of web performance optimisation as a means to bridge the gap between website visits and successful conversions. 

Businesses must prioritise and invest in improving web performance. So you can ensure a seamless user experience and maximise their chances of converting visitors into loyal customers.

An Overview of Web Performance and Performance Optimisation

Web performance refers to the speed, responsiveness, and overall efficiency of a website. It encompasses factors such as page load times, server response times, and the seamless delivery of content to users.

Performance optimization, on the other hand, involves the process of improving web performance through various techniques and strategies. It aims to enhance the user experience by reducing page load times, minimising server response times, and optimising resource delivery. 

Performance optimization techniques may include implementing caching mechanisms, compressing files, optimising images, and leveraging content delivery networks (CDNs).

Let's explore some of the web page performance techniques below:

1. Review/Audit your web performance 

Before diving into website optimisation, it is essential to conduct a review or audit to assess the current performance of your site. Here are some tools that can help in this process. Some popular options include:

Google Analytics and Search Console 

Google's free tools provide valuable performance statistics that can kickstart your audits. They offer insights into your website's performance and user experience. 

Additionally, Google Pagespeed Insights, which focuses on mobile and desktop devices, can provide recommendations for improving performance. It also utilises CrUX, the Chrome UX Report, which contains real user experience data from millions of websites.


GTmetrix is a web performance analysis tool that grades your page's speed and offers actionable recommendations for improvement. 

It evaluates factors such as page load time, and compliance with web performance best practices (e.g., CDN usage, image optimisation, CSS and JavaScript minification). 

By following GTmetrix's recommendations, you can enhance your page's speed and positively impact SEO. It also allows you to monitor performance changes over time.


WebPageTest evaluates web performance by conducting tests across multiple browsers and from diverse global locations.

It is suitable for web experts seeking detailed performance analysis and resolution optimization. While the reports from WebPageTest may take longer to generate, they provide comprehensive insights into your site's performance.

2. Accelerating Website

Accelerating a website with web performance optimization can be done with some techniques here:

Content Delivery Network (CDN)

Content Delivery Network (CDN) is a geographically distributed network of servers that stores cached copies of your website's static content. By serving content from the nearest server to the user's location, CDNs reduce latency and speed up content delivery.

Caching Mechanisms

Implementing caching mechanisms such as browser caching and server-side caching can significantly improve website speed. Caching allows storing frequently accessed data, reducing the need for repeated requests.

Compressing Files

Compressing files, such as HTML, CSS, and JavaScript, can significantly reduce their size and improve website loading times. Gzip compression is a widely used technique that reduces file sizes without sacrificing quality.

3. Avoid Excessive Use of Third-Party

Incorporating third-party tools and resources into your website can offer useful functionalities recommended by external parties. But, it is crucial to be mindful of the potential drawbacks. The more external resources are added, the greater the demand for system resources. 

Consequently, this can lead to slower website performance and potential security vulnerabilities. It is advisable to conduct a thorough review of all installed plugins and remove any unnecessary ones.

The best approach is to retain only essential plugins and ensure they are regularly updated to maintain optimal functionality and minimise any negative impact on your site's performance.

4. Tracking 404 errors

A crucial aspect of web performance optimization is monitoring and addressing 404 errors. 

A 404 error occurs when a requested page or resource cannot be found on a website. These errors can negatively impact user experience, SEO, and overall website performance.

Further, 404 errors often occur when there are broken or outdated backlinks pointing to non-existent pages on your website. These broken backlinks can result in missed opportunities for traffic and potential conversions.

5. Make a mobile priority 

With more people using smartphones and tablets to browse the internet, it's important to ensure that your site is mobile-friendly. Here's why it matters:

  • User Behaviour: Many people now access the internet through their mobile devices. By prioritizing the mobile experience, you cater to the preferences of a large user base, making them happy and engaged.
  • Mobile-First Indexing: Search engines like Google give priority to mobile-friendly websites. They use the mobile version of your site for indexing and ranking. When you prioritise the mobile experience, you increase your visibility in search results and attract more organic traffic.
  • Page Speed: Mobile users expect fast-loading websites. Slow-loading pages can make people leave your site quickly. By optimising your site for mobile devices, like compressing images and minimising server requests, you can improve page speed and overall performance.
