There are tools to help monitor page performance and assess your improvements. One of the best is PageSpeed Insights. It’s available as a web application and as the Lighthouse tab in Chrome’s DevTools (the same DevTools are also available in Edge, Opera, Brave, and Vivaldi).
Web page performance is more important than ever. Users expect a slick and responsive experience that rivals desktop applications. In addition, Google’s Core Web Vitals measure page performance – it influences PageRank and your Search Engine Optimization efforts.
WordPress runs more than a third of all websites but performance is affected by ineffective hosting, slow themes, and an over-reliance on plugins. You can fix most problems by switching to a good web host and using best practice performance techniques.
