The problem
WordPress can load CSS, JavaScript, plugin assets and built-in features that an individual site does not need. That unnecessary work can reduce PageSpeed results and make optimisation harder to control consistently.

What the work changed
WordPress can load CSS, JavaScript, plugin assets and built-in features that an individual site does not need. That unnecessary work can reduce PageSpeed results and make optimisation harder to control consistently.
Optimises WordPress automatically, removes features it does not need to speed it up significantly, and disables updates.
The plugin now runs on eight client websites. Real before-and-after checks showed an observed PageSpeed improvement of around 20%, while centralising performance controls that would otherwise require repeated manual work.
