A slow website is like a closed door for visitors. With 40% of users abandoning sites that take longer than 3 seconds to load, caching plugins have become non-negotiable for WordPress sites. These tools create static copies of your dynamic pages, reducing server load and speeding up content delivery. Let’s explore the top caching plugins to keep your site lightning-fast – and why pairing them with image optimization tools like Photozilla can take performance to the next level.
