How to Improve INP in WordPress

Improve Interaction to Next Paint by reducing long main-thread tasks and unnecessary JavaScript work.

Find the interaction

Use field diagnostics and browser tooling to identify which user interactions are slow rather than optimizing JavaScript blindly.

Reduce script cost

Remove unnecessary libraries and third-party tags, split expensive work and avoid loading features on pages that do not use them.

Delay safely

Delaying non-critical JavaScript can reduce early main-thread competition, but scripts tied to menus, consent, ecommerce or analytics require careful testing.

Theme and builder impact

Complex page builders and large component libraries can add interaction cost. Sometimes the durable fix is reducing front-end complexity rather than adding another optimizer.
