Before installation
Confirm whether your host or another plugin already handles page caching and check its compatibility guidance. Remove overlapping optimization features rather than letting several tools compete over the same HTML, CSS, or JavaScript.
Take a reliable backup and note critical flows such as login, forms, cart, checkout, account pages, search, and dynamic content.
Install and establish the cache baseline
Install and activate WP Rocket, then verify that representative public pages behave correctly. WP Rocket is designed to apply caching automatically, so do not rush into advanced file optimizations before confirming the basic site state.

Move through file optimization, media, preloading, database, and CDN settings with a test after each meaningful change. When a problem appears, revert the most recent change instead of stacking more tweaks on top.
Validate the result
Test more than the home page. Include a long article, category/archive page, conversion page, mobile viewport, and ecommerce templates where relevant. Performance work is complete only when speed improves without breaking the user journey.
