Website Design for Speed: Optimise for Ranking and User Experience


As website developers in Hamilton, NZ, we know how critical website speed is in delivering a positive user experience and achieving optimal performance. In this guide, we’ll explore why website speed matters, the factors affecting it, techniques for optimisation, and tools for measuring website speed.

Why Website Speed Matters

Imagine this scenario: you’re browsing the internet, and think you’ve finally found what you’re looking for, but the website takes forever to load. Frustrating, right? Well, you’re not alone. Research shows that users typically have very little patience for slow-loading websites, often abandoning them if they don’t load quickly. This is one reason why website speed is so crucial.

Slow-loading websites leads to higher bounce rates, lower engagement, and decreased conversions. Even if your website is visually appealing and well-designed, if it takes too long to load, users are likely to leave. 

Not only does this result in lost opportunities for engagement and conversion, but it also sends negative signals to search engines (aka Google), impacting your SEO rankings.

Speaking of SEO, website speed is a significant factor that search engines like Google consider when ranking websites. For additional insights on the technical aspects of website performance, Google Developers offers a comprehensive guide.

Google has stated that website speed is a ranking factor in its algorithm, underscoring the importance of delivering fast and responsive websites to users. Websites that load quickly not only provide a better user experience but also rank higher in search results, driving organic traffic and visibility.

By prioritising speed optimisation in your website design, you can enhance user satisfaction, reduce bounce rates, improve conversions, and boost your search engine rankings accordingly.

Factors Impacting Website Speed

Now that we’ve established why website speed is so crucial, we can discuss the factors that can impact your site’s loading speeds. As a website owner, it’s a good idea to have some idea of what causes poor website performance.

Hosting Provider and Server Location

Your choice of hosting provider and server location can significantly influence website loading speeds. Opting for a reputable hosting provider with robust infrastructure and servers (ideally located closer to your target audience) can help reduce latency and improve loading times significantly.

Image Optimisation

Images are often the largest elements on a web page, meaning they can contribute a great deal to slow loading times if they have not been optimised properly. 

Code Optimisation

Bloated, unnecessary, or inefficient code can vastly slow down your website’s performance. Minifying CSS, JavaScript, and HTML files by removing unnecessary characters and whitespace can help streamline code and reduce loading times. Explore W3C’s guidelines for efficient scripting to enhance your site’s performance.

Browser Caching

Browser caching allows browsers to store static resources such as images, CSS files, and JavaScript files locally; this reduces the need to re-download them each time a user visits your website. 

Content Delivery Networks (CDNs)

CDNs distribute website content across multiple servers worldwide, delivering it to users from the server nearest to their location. This reduces latency and improves loading times, especially for users accessing your website from different geographic regions. 

Tools for Measuring Website Speed

Let’s have a look at some tools that measure website speed. This will give you a way to evaluate the performance of your websites and identify areas for improvement. 

Tools for testing and measuring website speed for optimisation

Google PageSpeed Insights

Google PageSpeed Insights analyses the performance of your website on both mobile and desktop devices. This tool provides actionable insights and recommendations to improve your website speed, such as optimising images, leveraging browser caching, and reducing server response times.


GTmetrix provides detailed reports on page load times, page sizes, and other performance metrics, along with recommendations for improving speed and performance. It also offers a feature called Waterfall Chart, which visually displays the loading sequence of various page elements, helping you identify bottlenecks and areas for optimisation.

Pingdom Website Speed Test

The Pingdom Website Speed Test tool allows you to test the loading time of your website from various locations around the world. It provides performance grades, detailed performance insights, and recommendations for improvement, empowering you to enhance website speed and performance.

By regularly using these tools to measure website speed and identify areas for improvement, you can ensure that your websites are fast, responsive, and optimised for an exceptional user experience.

Techniques for Speed Optimisation

Now that we’ve identified some of the factors that can affect website speed, let’s explore some practical techniques that you can take to optimise the speed of your website. As website developers, we think it’s essential to have an understanding about these techniques so you can improve or get your developer to improve the speed and responsiveness of your website. 

Image Optimisation

Images are often the largest files on a web page; as such, they can significantly impact loading times. With this in mind, a great solution is to use tools such as Smush or WPOptimize to compress images without sacrificing quality. Additionally, implementing lazy loading can help defer the loading of images until they are needed, thereby reducing initial page load times.

Code Minification

Minifying CSS, JavaScript, and HTML files can help reduce file sizes, thus improving the website’s loading speed. Tools such as Minify, UglifyJS, and HTMLMinifier automatically remove unnecessary characters and whitespace from code files, thereby streamlining the code and reducing loading times.

Enable Gzip Compression

Gzip compression reduces the size of web page files by compressing them before sending them to the browser. This can lead to significant reductions in file sizes and much faster loading times. These days, most web servers support Gzip compression; as such, it is often a straightforward process.

Utilise Browser Caching

Browser caching allows you to instruct browsers to store certain resources locally, such as images, CSS files, and JavaScript files; as such, they don’t need to be re-downloaded each time a user visits your website, saving download times. You can configure caching settings using directives in your server configuration or plugins for popular content management systems like WordPress.

Implement Content Delivery Networks (CDNs)

CDNs distribute website content across multiple servers worldwide, delivering it to users from the server nearest to their location. By delivering content from servers that are closer to users, CDNs can significantly reduce latency and improve website speed. Popular CDNs include Cloudflare, Amazon CloudFront, and Akamai.

By incorporating these speed optimisation techniques into the website development and maintenance process, developers can ensure fast, responsive, and user-friendly websites that deliver an exceptional user experience and drive positive results for your clients.
