The importance of website speed and how to optimise it

People these days have incredibly reduced attention spans. So much so, that if your website takes longer than 3 seconds to load, you’ll increase your bounce rate by a whopping 47% on top of your usual bounce rate. 

And with most of Australia still running on 3G networks, bounce rates are a constant hindrance when it comes to website traffic. If you’re wondering what you can do to improve the bounce rate of your website in Australia, then read on.

Minimise HTTP requests

One of the most important things to keep in mind when optimising the speed of your blog is to minimise the number of HTTP requests it makes. When a user visits your blog, their browser sends requests to the server for all of the files needed to display the page, such as images, stylesheets, and JavaScript files. The more requests that are made, the longer it takes for the page to load.

To reduce the number of HTTP requests your blog makes, there are several things you can do:

  1. Combine files: Combining multiple CSS or JavaScript files into a single file can significantly reduce the number of requests the browser needs to make. This technique is known as "concatenation." Be sure to test the concatenated files thoroughly to ensure they still work as expected.
  2. Use CSS Sprites: If your blog uses multiple small images, using CSS Sprites can help reduce the number of requests the browser needs to make. CSS Sprites combine multiple images into a single larger image, which is then used to display each image individually.
  3. Minify files: Minifying your files removes all unnecessary characters from your code, such as comments and whitespace. This reduces the file size and helps speed up the loading process. There are many tools available online that can do this automatically.
  4. Reduce image sizes: Large images can take a long time to load, so it's important to optimise them for the web. You can reduce the size of your images by compressing them or resizing them. Be sure to find a balance between image quality and file size.

By implementing these strategies, you can significantly reduce the number of HTTP requests your blog makes, leading to faster load times and a better user experience.

Optimise images

Images are an essential part of any blog as they can help to make your content more engaging and visually appealing. However, large image files can significantly slow down your blog's loading times, which can negatively impact the user experience.

To optimise your images for the web, you can follow these tips:

  1. Compress your images: Image compression reduces the file size of your images without sacrificing quality. You can use a tool like Adobe Photoshop or online tools like TinyPNG or Compressor.io to compress your images. Aim for a balance between file size and image quality.
  2. Resize your images: Large images take longer to load, so it's important to resize your images to a reasonable size before uploading them to your blog. You can use tools like Adobe Photoshop or online tools like PicResize or Canva to resize your images to the correct dimensions.
  3. Choose the right file format: Different file formats are better suited for different types of images. JPEG is best for photographs, PNG is best for images with transparency, and GIF is best for simple animations. Choose the appropriate file format for each image on your blog.
  4. Use lazy loading: Lazy loading is a technique that defers loading images until the user scrolls to them. This can help to reduce the initial load time of your blog and improve the user experience.

By optimising your images using these tips, you can significantly improve your blog's loading times, leading to a better user experience and higher engagement with your content.

Use a content delivery network (CDN)

A content delivery network (CDN) is a group of servers distributed around the world that work together to deliver content to users more quickly and efficiently. By using a CDN for your blog, you can improve the loading times for your readers, regardless of where they are located in the world.

To use a CDN for your blog, follow these steps:

  1. Choose a CDN provider: There are many CDN providers available, including Cloudflare, Amazon CloudFront, and Google Cloud CDN. Each provider has its strengths and weaknesses, so be sure to research and compare them before making a decision.
  2. Configure your CDN: Once you have chosen a CDN provider, you will need to configure it to work with your blog. This may involve updating your DNS settings and configuring your CDN settings.
  3. Test your CDN: After you have configured your CDN, be sure to test it thoroughly to ensure that it is working correctly. Test your blog's loading times from different locations around the world to see if there is any improvement.

Using a CDN for your blog can significantly improve the loading times for your readers, especially for readers located far away from your server. By reducing the distance that data has to travel, a CDN can help to improve the user experience and keep readers engaged with your content.

Minimise code

Minimising the code on your blog can help to reduce the loading times and improve the user experience. When a user visits your blog, their browser needs to download and process all of the code before it can display the page. The more code there is, the longer it will take for the page to load.

To minimise the code on your blog, follow these tips:

  1. Remove unnecessary code: Go through your blog's code and remove any code that is unnecessary or redundant. This can include unused CSS styles or JavaScript functions that are not being used.
  2. Use code minification: Code minification removes all unnecessary characters from your code, such as comments and whitespace. This reduces the file size of your code and helps to speed up the loading process. There are many tools available online that can do this automatically.
  3. Use a caching plugin: A caching plugin can help to speed up your blog by storing frequently accessed data in the user's browser. This can include images, CSS, and JavaScript files. By storing this data locally, your blog can load more quickly, improving the user experience.
  4. Use a simple and lightweight theme: Choosing a simple and lightweight theme for your blog can help to reduce the amount of code that needs to be downloaded and processed by the user's browser. Avoid themes that come with many pre-built features that you may not use as they tend to be bulky and slow.

By minimising the code on your blog, you can significantly reduce the loading times and improve the user experience. This can help to keep your readers engaged with your content and improve your blog's overall performance.

Enable browser caching

Browser caching is a technique that allows your blog to store certain types of data, such as images, CSS, and JavaScript files, on the user's computer or device. By storing this data locally, the user's browser can load your blog more quickly, improving the user experience.

To enable browser caching for your blog, follow these steps:

  1. Edit your server's .htaccess file: The .htaccess file controls how your server handles certain types of requests. By adding a few lines of code to this file, you can enable browser caching for your blog.
  2. Set an expiration date for your files: When a file is downloaded from your blog, the browser checks the expiration date to see if it needs to be downloaded again. By setting an appropriate expiration date for your files, you can ensure that they are stored locally for as long as possible, reducing the number of requests to your server.
  3. Use versioning for your files: When you make changes to a file, such as a CSS or JavaScript file, the browser may still use the old version until the expiration date has passed. By using versioning, you can force the browser to download the new version of the file, even if the expiration date has not yet passed.

By enabling browser caching for your blog, you can significantly improve the loading times and reduce the number of requests to your server. This can help to improve the user experience and keep readers engaged with your content.
