1. Use appropriate file types

Different file types are best suited for different types of images. For example, JPEG is a good choice for photographs, while PNG is better for graphics with transparent backgrounds. Using the right file type can help reduce the file size and improve loading times.

2. Compress images

Compressing images helps reduce their file size which can improve loading times. There are several tools available that can help you compress images, such as TinyPNG or Kraken.io.

3. Choose the right resolution

Using images with too high of a resolution can slow down loading times and impact the performance of your website. On the other hand, using images with too low of a resolution can result in poor quality and a negative user experience. To find the right balance, use images with a resolution that is appropriate for the size at which they will be displayed.

4. Use descriptive, relevant file names

Using descriptive and relevant file names can help improve the SEO of your website and make it easier for users to find and understand your images. Avoid using generic file names such as "image1.jpg" or "photo.png."

5. Optimise alt text

Alt text, or alternative text, is a description of an image that is displayed if the image is unable to load or if the user is using a screen reader. Including alt text can improve the accessibility of your website and help improve its SEO. Be sure to use descriptive, relevant alt text that accurately describes the content of the image.

6. Use responsive images

With the increasing use of mobile devices, it's important to make sure that your images are responsive and look good on a variety of screen sizes. To do this, you can use the srcset and sizes attributes, which allow you to specify multiple versions of an image at different resolutions.

7. Optimise image thumbnails

Image thumbnails, or small versions of an image, are often used on websites to save space and improve the loading speed of pages. To optimise image thumbnails, use small, compressed versions of the original image and make sure that they are properly scaled.

8. Use lazy loading

Lazy loading is a technique that delays the loading of images until they are needed, which can help improve the loading speed of your website. There are several tools and plugins available that can help you implement lazy loading on your website.

9. Use image sprites

Image sprites are a single image that contains multiple images, which can be displayed using CSS. Using image sprites can help reduce the number of HTTP requests that are made when a web page is loaded, which can improve the page load time and overall performance of the website.

In conclusion, image optimisation is a crucial aspect of digital marketing that should not be overlooked. By implementing the 9 image optimisation tips discussed in this blog, you can significantly improve the performance and user experience of your website or eCommerce store.

Whether you're looking to improve loading times, boost SEO, or enhance the accessibility of your website, these tips can help you achieve your goals.
