By extracting information from the Chrome User Experience Report (CrUX) database, Google is able to discern how fast your average user finds your site.
That means that even if your website is lightning-fast on your end, visitors with older smartphones might experience delays — which could impact your speed score, and possibly your website’s ranking. If you haven’t already, it’s time to double down on speed optimization.
I am going to break down Google’s nine PageSpeed Insight Rules, list their best-practice advice, and then dive into some advanced steps you can take to optimize your site speed even more.
