Ever noticed a web site that loads particularly slowly, and wondered whether it's a problem with your internet connection or just a badly-constructed page?
Google PageSpeed is a free service that can help to provide the answers. And if you have your own web site, which you want to ensure is using all the best techiques for the optimum speed, PageSpeed will help you too.
Just head to https://developers.google.com/...d/pagespeed/insights and enter the address of the web page you want to check. Within a couple of seconds you'll get lots of useful tips about whether the page is running as fast as possible and, if not, what you can do to help speed it up.
