Website Speed: How to Make Your Online Store Load Faster

A slow store loses sales before anyone sees a product. This Insight covers how to measure your site’s speed, the Core Web Vitals Google uses, where online stores usually lose time, and the fixes that matter most.

Introduction to Website Optimisation

Website optimisation is the process of enhancing a website’s performance, user experience, and search engine rankings. It involves employing various techniques and tools to increase website speed, improve user engagement, and drive more conversions. By optimising a website, businesses can boost their online visibility, increase revenue, and stay ahead of competitors.

A crucial aspect of website optimisation is search engine optimisation (SEO). SEO helps websites rank higher in search engine results pages (SERPs), driving more organic traffic. This involves optimising various elements of the website, including content, technical aspects, and user experience, to meet search engine criteria. Ultimately, a well-optimised website not only performs better in search results but also provides a superior experience for visitors, leading to higher engagement and conversion rates.

Key Takeaways

• Website speed affects user experience, conversion rates and how Google assesses your pages.
• Regular analysis of current website speed and performance using tools like Google PageSpeed Insights and DebugBear is essential for identifying improvement areas.
• Compressing images, removing scripts you don’t need and caching pages can make a store noticeably faster.

Why Website Speed Performance Matters

Fast loading webpages significantly enhance user experience and encourage users to engage with the content. When users quickly find what they’re looking for without delay, they’re more likely to stay, explore, and convert. Slow pages do the opposite: more people leave before they buy.

Speed also plays a part in search. Google uses Core Web Vitals as part of how it assesses page experience. Relevant content still matters most, but a good page experience can help a page compete.

Analysing Your Current Website Speed

Before exploring optimisation techniques, evaluating your current website speed is necessary. One effective way to check page speed is by entering your website URL in PageSpeed Insights, which analyses performance for both mobile and desktop. Tools like Google Analytics and Search Console can track user behaviour and offer insights into your website’s performance. This initial assessment is crucial for identifying areas that need improvement.

Google measures how fast a page feels with three Core Web Vitals, and a page passes when at least 75% of visits meet each target. Largest Contentful Paint (LCP) measures how quickly the main content appears, and should be 2.5 seconds or less. Interaction to Next Paint (INP) measures how quickly the page responds when someone taps or clicks, and should be 200 milliseconds or less. INP replaced First Input Delay in March 2024. Cumulative Layout Shift (CLS) measures how much the page jumps around while it loads, and should be 0.1 or less.

Google’s PageSpeed Insights offers suggestions for enhancing page speed, focusing on metrics like First Contentful Paint and Largest Contentful Paint, which measure user experience. First Contentful Paint measures the time for the initial content to appear, impacting user perception of loading speed. Largest Contentful Paint assesses when the largest visible element on a webpage loads, reflecting overall user experience.

For more detailed performance analysis, DebugBear’s real-user monitoring offers critical data on how actual website visitors experience your website. Evaluating your website speed is necessary for identifying areas for improvement and enhancing user experience. With these tools, you can gather actionable data to guide your website optimisation efforts effectively, using real user metrics.

Key Factors Affecting Page Load Time

Understanding the factors that impact website speed is the first step toward effective optimisation. Server response time depends on your hosting and how efficiently your site runs. A slow server delays everything else on the page.

Large HTML and CSS files can also lead to poor website performance due to increased loading times. Poorly structured code and superfluous elements add unnecessary complexity, further slowing down your website. Large image and file sizes are another common culprit, as they can notably impact the loading speed of web pages.

Minimising HTTP requests is necessary because each request can slow down website loading. Techniques such as image compression, enabling browser caching, and removing large page elements can reduce load time. Understanding these factors allows website owners to implement targeted optimisation strategies to enhance site performance.

Best Practices for Improving Website Speed Performance

A combination of best practices that address different site components is required to improve website speed performance. An initial audit of site performance and identifying pain points is necessary for effective optimisation. Utilising a page speed checker can reveal opportunities to enhance page load time and highlight areas that need attention.

Optimising images, minimising HTTP requests, and enabling browser caching are key practices in the optimisation process. These strategies not only improve page performance but also contribute to a better user experience. Each is covered below.

Optimise Images

Images often make up a significant portion of a webpage’s load size. Compressing images is a key strategy for enhancing website performance. Tools like EWWW Image Optimizer automate this with little visible loss in quality, and can convert images to WebP, which is usually much smaller than JPEG or PNG.

Optimising image alt text not only improves accessibility but also enhances image search rankings, contributing to overall site optimisation.

Lazy loading, which reduces initial load time by only loading images as they enter the viewport, is another effective technique. Identifying images that can be optimised is essential to keep your site lightweight and fast. By implementing these techniques, you can significantly reduce page load time, address slow loading pages, and enhance user experience.

Minimise HTTP Requests

Every file your page loads adds to the load time, but on modern hosting the size and type of each file matter more than the count. The biggest wins usually come from removing what you don’t need: unused plugins, old tracking pixels and apps that load scripts on every page.

Check which scripts load on your product and checkout pages, then remove or delay anything that isn’t needed there.

Enable Browser Caching

Browser caching can significantly enhance speed for returning visitors by storing web data locally. This reduces the need for repeated resource downloads on subsequent visits.

Caching headers on your web server control how long resources are stored before refreshing. Caching mechanisms can reduce server response time, thereby improving overall website performance.

Advanced Techniques for Speed Optimisation

Advanced techniques can offer significant speed improvements for those looking to elevate their optimisation efforts. Content Delivery Networks (CDNs) reduce loading time by delivering website content from servers closer to the user. Other advanced methods include reducing server response time and utilising asynchronous loading.

Here is how each one works.

Implementing a Content Delivery Network (CDN)

A CDN reduces latency and speeds up website loading times by loading the site from the closest server to the user. Utilising multiple geographically distributed servers, CDNs decrease the distance data travels.

A CDN improves user experience and optimises server load by efficiently distributing content. This approach is especially advantageous for websites targeting a global audience, as it helps keep loading times fast wherever visitors are.

Reducing Server Response Time

A reliable hosting provider can significantly impact server response times. Database query optimisation is also necessary for decreasing server response times.

A combination of reliable hosting and optimised database queries results in better server response times and overall website speed. These steps are crucial for maintaining a fast and efficient website.

Utilising Asynchronous Loading

By default, the browser pauses building the page while it downloads and runs each script. The ‘async’ attribute for JavaScript files enables non-blocking loading, improving page rendering times.

The ‘defer’ attribute ensures JavaScript executes only after the HTML has been fully parsed. Placing script tags at the bottom of the HTML document can further improve page load times. These techniques help in rendering pages faster, enhancing user experience.

Technical SEO

Technical SEO is a critical component of website optimisation that focuses on improving a website’s technical aspects to enhance search engine rankings and user experience. This includes optimising page load time, ensuring mobile responsiveness, and enhancing website security.

Optimising website code, images, and other media can significantly reduce page load time, improving website speed. Ensuring that your website is mobile-friendly is also crucial, as a significant portion of web traffic comes from mobile devices. Additionally, maintaining a secure website builds trust with users and search engines alike.

By addressing these technical aspects, businesses can enhance their search engine rankings, attract more traffic, and boost conversion rates. Technical SEO is an ongoing process that requires regular updates and monitoring to maintain optimal performance.

Where Online Stores Usually Lose Speed

Most of the speed problems we see on eCommerce sites come from the same few places.

• Product and collection images. Photos uploaded straight from a shoot, with no compression or resizing, are the most common cause of a slow product page.
• Apps, plugins and third-party scripts. Reviews widgets, live chat, tracking pixels and pop-ups each add code, often on every page. They build up over time, and few stores remove the ones they stop using.
• Sliders and hero video. A full-width slider or video at the top of the home page is often the largest element on screen, so it decides your LCP.
• Basket, checkout and account pages. On WooCommerce these pages are personal to each shopper, so they can’t be served from the page cache. They depend on fast hosting and a lean set of plugins.

Test a product page and your checkout, not just the home page. They are the pages where the sale happens.

Monitoring and Continuous Improvement

Continuous monitoring spots performance issues early, before customers notice them. Alerts can quickly identify performance drops or downtime, minimising potential visitor frustration.

Run a speed check after every major change, such as a new plugin, app or theme update.

Regular use of performance analysis tools is necessary for tracking website speed and optimising accordingly. Consistently reviewing website analytics can reveal user behaviour patterns, guiding further optimisation efforts. This ongoing process is vital for maintaining an optimised website.

Website Optimisation Tools to Help You Optimise Website Speed

Google PageSpeed Insights tests a single page on mobile and desktop, and shows real-user data alongside the lab test when the page has enough traffic. The Core Web Vitals report in Google Search Console shows which groups of pages pass or fail across your whole site. Screaming Frog is a crawler rather than a speed test, but it finds broken links, redirect chains and oversized images across the site.

DebugBear adds continuous monitoring and real-user data, so you can see how speed changes over time rather than on a single test. Test on mobile first, because that is where most stores are slowest.

Common Mistakes to Avoid

The most common mistake is testing only the home page, on a fast office connection. Test your product pages and checkout as well, and test them on mobile.

Other mistakes we see often: chasing a perfect lab score instead of improving real-user data, adding a new plugin or app for every small feature, uploading images straight from the camera, and putting an autoplay video at the top of the home page.

Summary

In summary, website speed is a critical factor in user experience, conversion rates, and search engine ranking. By understanding the key factors affecting website speed and implementing best practices and advanced techniques, you can significantly improve your site’s performance. Continuous monitoring and optimisation are essential to maintain these improvements.

Effective website optimisation can transform your site into a powerful conversion tool, attracting and converting visitors into loyal, paying customers.

A fast store keeps shoppers moving towards checkout, and helps your pages compete in search.
