Google are intent on making the web faster.
The speed your page loads has become an important part of their ranking criteria. So it is a good idea to optimise your site as best as you possibly can.
You can test your web page’s speed using Googles free page speed analyser here: https://developers.google.com/speed/pagespeed/insights
Ultimately, you should be aiming for the feedback after the test to say ” this page already follows these best practices. Good job!”
