Google PageSpeed Insights is just what it says – insight.
If you were to make all the changes suggested by the tool, the likelihood is that your site would not work or the presentation would be off.
Our focus is on one thing: true loading time. It’s common for a site to have mixed scores but load very quickly. We consider the speed testing tools and what they say and balance their recommendations with your customer’s needs.
What you want are the fastest times possible and a website that looks good and operates like its supposed to.
