Top WordPress Plugins for Speed Optimization
Below is a carefully curated list of the best plugins to speed up your WordPress website, categorized by their primary functions.
1. WP Rocket – The Ultimate Caching Plugin

If you’re looking for a free caching plugin, W3 Total Cache is one of the most popular options.
Key Features:
