For free options, WP Super Cache and W3 Total Cache are excellent choices. The “best” plugin ultimately depends on your specific needs, technical expertise, and budget.

Critical CSS is extracted and loaded first, while non-essential scripts are deferred until after the page renders.

How many plugins should I have for WordPress speed optimization?

For most WordPress sites, you only need 2-3 essential performance plugins:
A caching plugin (like WP Rocket or WP Super Cache)
An image optimization plugin (like Smush)
