We are all trying to increase our sites speed and give our users a better experience and one often overlooked method is to leverage browser caching.
For anyone who doesn’t know exactly what we are trying to do here, I’ll try and explain. Browser caching stores elements of internet sites for an amount of your time so as to form them load quicker. For instance, if you look at 10 pages on a website and it has the same background image, logo, social media icons and so on, we can store these in the browser in order that they don’t keep being downloaded.
