What is INP by funnel point
INP by funnel point breaks down your Interaction to Next Paint (INP) by key user journey events, called funnel points. These funnel points represent critical stages like landing, product, cart, or checkout — and are auto-generated by Uxify for each site (but can be customized in Settings).
INP measures how fast your site responds to user interactions like clicks or taps. Poor responsiveness at key funnel points can directly impact user satisfaction and conversion.
INP by funnel point sample
Should you worry
A healthy INP by funnel point view shows all green — meaning your site is responsive at each step of the user journey.
Even if some funnel points are slightly faster than others, as long as they’re green, you’re in good shape. The more consistently green your INP across funnel points, the smoother your experience feels to users.
Unhealthy INP by funnel point
If you see yellow or red on specific funnel points — like Product or Cart — it’s a strong sign that interaction delays are affecting your most important pages.
Common causes include:
Heavy JavaScript blocking button clicks.
Slow event handling on modals, tabs, or custom UI components.
Personalization scripts delaying interactivity for logged-in users.
When INP is high at key moments, users may get frustrated just when they're ready to take action — hurting both engagement and revenue.
Resolving unhealthy INP by funnel point
Go-to action plan to resolve an unhealthy INP by funnel point:
Ask Uxi to analyze your INP by funnel point values and suggest improvements.
Use Filters to isolate the worst-performing funnel points and traffic segments.
Simulate INP of the suspected breakdown to see if fixing it will resolve the INP by funnel point. If yes, this is where the resolution focus should be.
Use an automated INP optimization tool like INProve to improve your INP by funnel point values.
Once you’ve improved INP, set an alert to be the first to know if it starts worsening again.
