WordPress website's performance is crucial for providing a great user experience. In this blog, I'll share some practical tips for optimizing your website's performance and achieving a perfect score of 100 in Google PageSpeed Insights. I'll cover topics such as image optimization, leveraging caching and CDNs, and minimizing HTTP requests. I'll also discuss how to optimize your website's code and databases, and highlight some of the best plugins and tools that can help you improve your website's performance.
