SEO Image Optimisation – Tips for Your Images

SEO Image Optimisation – Tips for Your Images

Search engine optimisation (SEO) are various methods used to improve website ranking on search engine result pages (SERPs) like Google. With proper SEO in place, a website is easier to find on search engines, meaning more organic traffic and potential sales.

One of the more often-overlooked components of SEO is image optimisation. While most understandably focus on target keywords and website copy, images also need to be optimised for SEO ranking.

What is SEO Image Optimisation?

Image optimisation is the process of adjusting images to ensure that they don’t impact website performance.

While it may not be obvious, website images may be causing performance issues, such as slowing loading speeds. If a website takes too long to load, users are guaranteed to head elsewhere, highlighting the importance of SEO optimisation.

In most cases, SEO image optimisation involves making slight tweaks to the size and format of the website images. The goal is to make images the smallest size possible while retaining the highest quality.

Tips for SEO Image Optimisation

Image optimisation is a simple yet effective strategy for improving SEO of a website. Here are some of the best strategies you can use to optimise your images for SEO:

Focus on Image Quality

You always want to ensure your website images have the best quality possible without being an excessive size. Poor quality images with low resolutions and lots of pixels don’t send the best message to users about your site. In fact, if your images aren’t up to scratch, they might be turning away potential customers!

Ensure that you focus on optimising images to the highest quality possible. Original images typically have the highest quality and rank best for SEO. Stock images are a cost-effective alternative, offering quality and reliability for a more affordable rate.

Use the Right Image File Names

Google doesn’t just crawl website text for SEO – it also reads image file names. So, if your images have generic titles, you’re missing out on the opportunity to integrate keywords. Consider renaming each image file with a target keyword to improve SEO ranking.

Resize Images

Bigger is not always better when it comes to image sizes on your website. In fact, larger images may be actively turning users away from your website because they’re slowing loading times.

Therefore, it is recommended that you resize all your images to ensure that they are no larger than 150kb. It may take some time to resize lots of images, in which case you might want to outsource the process to SEO specialists to save time and resources.

Don’t Forget About Captions

A caption is a simple line of text beneath the image to explain what it is. While a simple method, the result can be surprisingly effective, making site images more noticeable to browsing users. 

Consider integrating keywords into your image captions to guide users to products they’ve already searched for.


SEO image optimisation ensures that website images aren’t hindering your business. If a website has unoptimized images, it will cause the website to slowly load, turning away potential customers.

Optimising images is a quick and easy process that will improve rankings on search engines, making it a worthwhile effort for any business website.
