Google is fickle when it comes to providing information that can be helpful for publishers. They rarely publish SEO guidelines and are equally silent on algorithm changes overall apart from self-serving tweets from a few key employees.
One tool that Google does provide that website operators can use is PageSpeed Insights. This service is designed to score your site on a 100 point scale which is somewhat analogous to site speed. The higher your score, the “faster” your site is as perceived by Google. Whether this score itself is an SEO factor remains to be seen, but many experts would say that the technical components that go into the score most certainly are. But if we were to ignore this altogether, the simple truth is that if Google shares tools that can help publishers, you'll do well to at least look into it more.
In this guide, we wanted to breakdown how we look at PageSpeed Insights, and highlight several ways you may be able to improve your PSI score as well.
