How to Optimise Website Images for Better SEO Performance
Image optimisation is essential to your SEO performance, it is the reduction of file sizes and dimensions, without losing quality. When you reduce the image file size, you speed up your page loading time, which is a major ranking fact for search engines.
What you need to realise is that image file size is not the only image optimisation step you must take to boost SEO performance in the long run.
Images are essential to your website. They have a direct impact on user experience (UX), visibility, and ranking.
Here are some important things you need to know:
There are a number of optimisation steps to take for website images to improve SEO performance.
Image sizes are the dimensions of your images. The file size tells you how much space is needed to store the image on the server, usually in kilobytes. High resolution images with large dimensions can slow down the page loading times. Scaling down the image, ensures your image works on your site, speeding up page loading times and improving user experience (UX).
File names are important to your SEO efforts. Adding relevant and descriptive keywords, you can optimise your image file name to boost SEO. Add your targeted keywords at the beginning of the name and separate them using hyphens, do not use underscores, as search engines don't understand them. Choose a file name that will resonate with your audience and with search engines.
Unique images receive higher rankings in search engine results pages (SERPs), over stock images.
The type of image you select also plays a role in SEO. You want to use supported and web-friendly image formats, these include JPEG, PNG, or WebP. These balance the image quality and size, helping to speed up page loading times.
Search engine crawlers need information regarding your images, so they understand the content. Alt text, or alternative text, provides the search engine with the information it needs, so it can index and rank you images. Alt-text is also important when improving the accessibility of your website for visually impaired users, helping them understand the context of the images.
Responsive images have the ability to adapt to any resolution and screen size, boosting user experience. It ensures your visitors can view the image in good quality on any device and any screen size.
Content delivery networks (CDNs) help to reduce images, delivering them accurately to any device and sending the images instantly from the network. They are able to improve page loading speeds considerably, and in turn your SEO performance gets a boost, along with user experience.
