I recently had the pleasure to listen to Ilya Grigorik give a talk at Velocity in NYC on Breaking the 1000ms Mobile Barrier. During the talk, Ilya used PageSpeed Insights to demonstrate that several high profile websites had overlooked some very simple and common optimizations and resulted in poor PageSpeed scores. For the unfamiliar, Pagespeed Insights is a web based tool created by Google that analyzes the content of a web page, then generates suggestions to make that page faster.
After Ilya’s talk ended, I started to think more about why performance always seems to be an afterthought with developers. As I pondered this thought, I kept coming back to the following question:
How hard is it to get a perfect PageSpeed Insights score?
It can’t be that hard, right? Well…there is only one way to find out!
