If you’re not worried about the page speed of the sites you’re building, you should be. Most of us won’t wait very long for a site to load – research says we have about 3 seconds before our users will go elsewhere.
One of the key ways you can speed up your website is by ensuring that your images are optimized properly.
That means your images are the right size – both dimensionally and are the correct file size – and ensuring that you use the right image types. There’s also an awesome side benefit to optimizing your images – improving your SEO and on-site accessibility. The key thing here though is most of this work happens before you even think about uploading your images to a website.
