WordPress powers over 40% of all websites on the internet, making it one of the most popular CMS platforms. However, without proper optimization, your site can become slow, insecure, and less user-friendly. A well-optimized WordPress site improves speed, SEO rankings, and user experience, which ultimately drives more traffic and conversions.
In this post, we’ll cover the top best practices to optimize your WordPress site.

Your hosting provider plays a critical role in your site’s performance. Look for:
