Ever browsed through a slow website? Sometimes you won’t even have the patience!
The fast-paced nature of the internet in today’s time means that website platforms cannot afford to ignore slow website loading speeds. Research has shown that a slow loading website can lead to up to 40% of traffic lost and even 7% reduction in conversions.
What’s more, Google has set website loading performance as a key ranking factor for their Core Web Vitals metrics which determines the SEO ranking of a website based on real-user experiences. Websites with a fast loading time are then more likely to be rewarded with a higher SERP ranking than those with a slower speed. Ultimately, by ensuring your loading speed is up to par, your website will reap the benefits of high traffic engagement and high SEO ranking.
In this article, we will go through the key areas of website speed optimization, performance optimization techniques to keep your digital platform up to speed and responsive design practices to maintain speed on cross-platform devices.
What Are the Common Elements That Affect Website Speed?
Regular website maintenance is essential to ensure your platform continues to run smoothly. Conducting audits with tools like SEMRush and Google Search Console can help uncover hidden issues that may not be obvious at first glance.
For content-heavy websites in particular, performance issues often arise that can slow down loading times. By identifying and optimising these issues, you can maintain strong performance and provide a better user experience over time.
What Factors Can Slow Down a Website?
Large Images
High-resolution images may look great but can significantly increase page load times, especially on mobile devices with limited bandwidth.
Inefficient Scripts
Unnecessary scripts, excessive third-party integrations, and bloated code can slow down rendering and execution.
Unoptimized Rendering Practices
Rendering the process of converting code into a visible site, can be slowed by inefficient CSS, lack of caching, or poor coding practices.
Server-Side Issues
Slow server response times due to weak hosting, database bottlenecks, or inefficient queries can harm performance.
In addition, websites must be optimized for multiple screen sizes. Smartphones, tablets, and desktops may process the same site differently due to their varying hardware and interaction methods.
5 Techniques to Optimize Website Speed
Knowing where and how to optimize your website will depend on how complex your website is, as there are as many techniques as there are areas of your platform you can optimize. In this next section we will go through the different areas which you can consider to optimize for faster loading speed. Optimizing Images, Scripts, and Other Resources for Faster Loading Images, scripts and other elements contribute significantly to a website’s overall size. Here’s how to optimize them for faster loading times:
1. Reduce image file size
Use tools like TinyPNG or Smush to compress images without sacrificing significant quality.
2. Utilize appropriate image formats
Employ formats like JPEG for photos and PNG for graphics with transparency.
3. Resize images to their display size
Avoid unnecessarily large images that need to be scaled down in the browser.
4. Apply Lazy Loading
Load images as they appear onto the screen rather than appear all at once
How To Optimizing with Lazy Loading and Deferred Loading
Lazy Loading
Delays the loading of non-critical resources until they are scrolled into view. This improves initial website loading speed as only the content which will be shown on screen is loaded initially.
Deferred Loading
Deferred loading delays the execution of non-critical scripts until after the page content has loaded. This prevents scripts from blocking the rendering of other elements, further improving perceived performance.
How To Optimizing HTTP Requests
Responsive websites adjust to different screen sizes, which can potentially create additional HTTP requests due to various resources required for different devices. Here are some best practices to minimise the number of HTTP requests:
1. Leverage responsive images
Utilize the ‘srcset’ and ‘sizes’ attributes in your HTML code for the most appropriate image size for each device, reducing unnecessary requests for images not needed on specific devices.
2. Combine CSS and JavaScript files
Combine multiple CSS and JavaScript files into fewer files to reduce the number of HTTP requests.
3. Utilise a Content Delivery Network (CDN)
A CDN stores cached copies of your website’s content across globally distributed servers, only delivering content when requested from the nearest server to minimize latency and improve loading times.
How To Optimize Rendering for Browsers
When loading up a website, browsers go through a few steps to read the code, download the resources and ‘paint’ the site onto the screen. To make it as smooth as possible, consider these techniques:
1. Minimize critical render path (CRP) resources
The CRP is the minimum set of resources needed to render the initial view of the page. Prioritize loading and optimizing resources critical for initial rendering.
2. Reduce layout shifts
Layout shifts occur when elements on the page unexpectedly shift positions during loading. Defining explicit widths and heights for certain elements and avoiding layout changes based on user interactions can help avoid this.
3. Utilize browser caching
Leverage browser caching mechanisms to store frequently accessed resources locally on the user’s device, reducing the need to download them again the next time they visit.
How to Optimize Typography and Fonts
Believe it or not, the variety of fonts and text styles you use can also impact your website loading speed. Some best practices to keep this area optimized include:
1. Use relative units
Use relative units like ‘em’ or ‘rem’ for font sizes, line heights, and margins instead of absolute units like pixels. This allows elements to scale proportionally based on the viewport size, ensuring proper readability across devices.
2. Limit the number of web fonts
Each additional web font adds an HTTP request, potentially impacting performance. Use a limited number of web fonts strategically for optimal results.
3. Font display properties
Utilise the font-display property in CSS to control how the browser displays text while the web font is loading. Options like ‘swap’ ‘fallback’ and ‘optional’ allow fine-grained control over the loading behaviour, prioritising initial page rendering if necessary.
4. Font subsetting
Include only the characters used on your website within the web font file, reducing file size and minimizing unnecessary downloads.
5. Font face descriptor strategies
Utilize ‘font-weight’ and ‘font-style’ descriptors in the ‘@font-face’ rule to define different variations of the same font family, allowing for efficient switching between them without additional requests.
How To Measure Your Web Improvements
It’s important to track the results of your performance optimisation efforts. A healthy website should continue to grow with more content and features, which in turn requires ongoing optimisation to run smoothly.
