Optimising images for faster load times

Images often make up a large portion of a website’s total data. By optimising images, you can significantly reduce the number of HTTP requests and improve load times. Start by compressing images without losing quality. Tools like TinyPNG or ImageOptim can help you achieve this. Additionally, consider using modern image formats like WebP, which offer better compression rates than traditional formats like JPEG and PNG.

Another effective strategy is to use responsive images. This means serving different image sizes based on the user’s device. For instance, a mobile user doesn’t need a high-resolution image meant for desktop screens. By using the `srcset` attribute in your HTML, you can ensure that the appropriate image size is loaded, reducing unnecessary data transfer.

Combining and minifying CSS and JavaScript files

CSS and JavaScript files are essential for a website’s functionality and design, but they can also contribute to a high number of HTTP requests. Combining multiple CSS and JavaScript files into a single file can reduce the number of requests. Tools like Gulp or Webpack can automate this process, making it easier to manage.

Minifying these files is another crucial step. Minification removes unnecessary characters like spaces and comments, reducing the file size. This not only speeds up load times but also decreases the amount of data that needs to be transferred. Our expert developers at iWeb have extensive experience in optimising CSS and JavaScript files, ensuring your website runs smoothly and efficiently.

Leveraging browser caching

Browser caching allows you to store static files on a user’s device, so they don’t have to be reloaded every time the user visits your site. This can drastically reduce the number of HTTP requests and improve load times. By setting appropriate cache headers, you can control how long files are stored in the cache.

For example, you can set a long cache duration for static assets like images, CSS, and JavaScript files. This way, returning visitors will experience faster load times as their browser retrieves these files from the cache instead of making new HTTP requests. The team at iWeb can help you implement effective caching strategies tailored to your website’s needs.

Using content delivery networks (CDNs)

A Content Delivery Network (CDN) can distribute your website’s static files across multiple servers worldwide. This not only reduces the load on your main server but also ensures that users receive content from a server geographically closer to them, speeding up load times. CDNs like Cloudflare or Akamai can significantly reduce the number of HTTP requests by caching your static files.

Moreover, CDNs can handle large traffic spikes, ensuring your website remains fast and responsive even during peak times. With iWeb’s 29 years of e-commerce experience, we can help you integrate a CDN into your website, enhancing its performance and reliability.

Implementing lazy loading for images and videos

Lazy loading is a technique where images and videos are only loaded when they are about to enter the viewport. This reduces the initial number of HTTP requests, speeding up the page load time. By deferring the loading of non-essential media, you can ensure that critical content is displayed to the user as quickly as possible.

Implementing lazy loading is straightforward with modern JavaScript libraries like LazyLoad or by using the `loading=”lazy”` attribute in your HTML. Our talented team at iWeb can assist you in setting up lazy loading, ensuring your website remains fast and efficient.

Reducing the number of plugins and third-party scripts

While plugins and third-party scripts can add valuable functionality to your website, they can also increase the number of HTTP requests. It’s essential to evaluate the necessity of each plugin and script. Remove any that are redundant or not providing significant value.

For essential third-party scripts, consider loading them asynchronously or deferring their loading until after the main content has loaded. This ensures that these scripts don’t block the rendering of your page, improving the overall user experience. iWeb’s e-commerce expertise can help you streamline your website, ensuring it remains functional without unnecessary bloat.

Utilising server-side rendering (SSR)

Server-side rendering (SSR) can improve the performance of your website by generating the HTML on the server rather than the client. This reduces the number of HTTP requests needed to render the page, as the browser receives a fully-formed HTML document. SSR is particularly beneficial for dynamic content and single-page applications (SPAs).

By implementing SSR, you can ensure that your website loads faster and is more accessible to search engines. Our talented in-house team at iWeb can help you set up server-side rendering, leveraging our expertise in e-commerce to enhance your website’s performance.

Implementing HTTP/2

HTTP/2 is a major revision of the HTTP protocol that offers several performance improvements over HTTP/1.1. One of the key features of HTTP/2 is multiplexing, which allows multiple requests to be sent over a single connection. This reduces the overhead associated with multiple HTTP requests, speeding up load times.

Additionally, HTTP/2 supports header compression and prioritisation, further enhancing performance. By upgrading to HTTP/2, you can ensure that your website is taking advantage of the latest web technologies. The team at iWeb can assist you in implementing HTTP/2, ensuring your website remains fast and efficient.
