A simple guide to image optimisation


Image optimisation is not something you can afford to skip. It’s a process of delivering high-quality images in the right format, dimensions and resolution while keeping the file size as small as possible. It’s essential if you want your website to load quickly. Optimised images also contain relevant keywords in the file name, helping to boost your site’s SEO

Image optimisation is about reducing the file size of your images as much as possible without sacrificing quality. It’s one of the simplest ways to speed up your website and ensure your page load times stay low.  

Image optimisation is also about image SEO. That is, getting your images to rank highly on Google and other image search engines.  

What is an optimised image anyway?  

An optimised image is a low-res, small file size (usually 10kb – 500kb) with image dimensions no bigger than 2000px for a full screen image or 1200px for a ‘normal’ image size. It’s important to note that lowres doesn’t mean low quality. Highres is perfect for print, but lowres is what you need if you want your images to look good and load quickly on the web.  

To help Google find your images and display them when a user searches for a particular term, optimised images also have keywords in the file name relevant to the content they’re associated with.  

What happens if I don’t optimise images? 

You run the risk of exceeding your hosting limit and causing your site to crash. If you manage to stay online, chances are your website will load slowly. This could be bad news for your business.  

Google penalises slow loading sites, meaning you’ll either rank low or not at all in their search results. Consumers are also super impatient! On average, you have around 3 seconds to win their attention once they’ve landed on your site. Amazon found that if their pages slow by as little as 1 second, they lose $1.6 billion a year.  

Ok, how do i do it?
