INP (Interaction to Next Paint) is a new Core Web Vital that measures interactivity by seeing how long it takes for a page to give visual feedback in response to user input. By capturing the worst of these interactions, the INP metrics helps developers understand and debug resources that are contributing to a poor user experience.
The INP metric is already built into a wide variety of testing tools including Web Page Test and Lighthouse. As a WordPress site, plugin or theme developer, it is important to understand what INP is and how you can leverage it to improve the user experience your site or product delivers.
In this talk, we will discuss:
- What INP measures exactly and what poor experiences it helps capture
- How to measure your site’s INP – RUM & lab data
- How to improve your site’s INP – top culprits
- INP best practices for WordPress developers
By the end of this talk, you will have a good understanding of INP and how you can improve your user’s experience by improving your INP!
