Optimise Web Performance

Introduction to Web Performance Optimisation

As a business owner in the UK, having a website is no longer a luxury, but a necessity. However, with the ever-increasing competition online, it's not enough to just have a website – it needs to be fast, efficient, and provide a seamless user experience. This is where web performance optimisation comes in. According to a study by Akamai, a one-second delay in page loading time can result in a 7% reduction in conversions. In this article, we will delve into the technical aspects of web performance optimisation, providing you with a comprehensive guide to improve your website's speed, user experience, and ultimately, your bottom line.

Understanding Web Performance Metrics

Before we dive into the nitty-gritty of web performance optimisation, it's essential to understand the key metrics that measure a website's performance. These include:

• Page Load Time (PLT): The time it takes for a webpage to fully load.
• First Contentful Paint (FCP): The time it takes for the first piece of content to be displayed on the screen.
• Time To Interactive (TTI): The time it takes for a webpage to become interactive, allowing users to click, scroll, and engage with the content.
• Speed Index: A measure of how quickly the content of a webpage is populated.

These metrics can be measured using tools such as WebPageTest, Google PageSpeed Insights, and GTmetrix.

Why Web Performance Matters

A slow website can have a significant impact on your business, leading to:

• Higher Bounce Rates: A study by Forrester found that 57% of users will abandon a website if it takes more than three seconds to load.
• Lower Conversion Rates: As mentioned earlier, a one-second delay in page loading time can result in a 7% reduction in conversions.
• Poor User Experience: A slow website can lead to frustrated users, resulting in negative reviews and a damaged brand reputation.

On the other hand, a fast and efficient website can lead to:

• Increased Conversions: A study by Walmart found that for every one-second improvement in page loading time, they saw a 2% increase in conversions.
• Improved User Experience: A fast website provides a seamless user experience, leading to increased engagement and customer satisfaction.
• Better Search Engine Rankings: Google takes into account page speed when ranking websites, making it essential to optimise your website's performance for better search engine rankings.

Technical Optimisation Techniques

Now that we've covered the importance of web performance optimisation, let's dive into the technical aspects of improving your website's speed and efficiency. Here are some techniques to get you started:

Optimising Images

Images can significantly impact your website's page load time. Here are some techniques to optimise your images:

• Compressing Images: Use tools like TinyPNG or ImageCompressor to compress your images without sacrificing quality.
• Using Image Formats: Use the correct image format for your images, such as JPEG for photographs and PNG for graphics.
• Lazy Loading: Use lazy loading to load images only when they come into view, reducing the initial page load time.

Minimising HTTP Requests

HTTP requests can significantly slow down your website. Here are some techniques to minimise HTTP requests:

• Combining Files: Combine multiple CSS and JavaScript files into a single file to reduce the number of HTTP requests.
• Using Sprites: Use sprites to combine multiple images into a single image, reducing the number of HTTP requests.
• Enabling Keep-Alive: Enable keep-alive to allow multiple requests to be sent over a single connection, reducing the overhead of establishing multiple connections.

Enabling Browser Caching

Browser caching allows frequently-used resources to be stored locally on the user's browser, reducing the need for repeated HTTP requests. Here are some techniques to enable browser caching:

• Setting Cache-Control Headers: Set cache-control headers to specify how long resources should be cached for.
• Using Expires Headers: Use expires headers to specify when resources should expire and be re-fetched.
• Enabling ETags: Enable ETags to allow the browser to validate cached resources and reduce the need for re-fetching.

Optimising Server-Side Performance

Server-side performance can significantly impact your website's speed and efficiency. Here are some techniques to optimise server-side performance:

• Using a Content Delivery Network (CDN): Use a CDN to distribute content across multiple servers, reducing the load on your origin server and improving page load times.
• Enabling Gzip Compression: Enable Gzip compression to reduce the size of HTTP responses and improve page load times.
• Optimising Database Queries: Optimise database queries to reduce the time it takes to retrieve data and improve server-side performance.
