What is INP by cookies on/off
INP by cookies on/off shows how the Interaction to Next Paint (INP) varies based on whether users had cookies enabled or disabled in their browser during their session.
This matters because cookie state can significantly affect the interactive layer of your site — from A/B testing scripts to client-side personalization, modals, and event tracking.
And when those elements misfire or get delayed in one mode (especially "cookies off"), the interaction experience can take a hit.
Healthy INP by cookies on/off sample
Should you worry
If both cookie states show green bars, congrats — your interactivity isn’t compromised by the user’s privacy choices.
No extra delay from consent modals or script fallback
No broken personalization logic interrupting input handling
Consistent experience across default and privacy-focused modes
This is a strong indicator your frontend is resilient and adaptive.
Unhealthy INP by cookies on/off sample
Delays typically arise when cookies are off, and your site depends on cookies for:
Triggering personalization or A/B variations post-interaction
Loading dynamic UI components (e.g., chatbots, overlays, region-switchers)
Failing gracefully when analytics or marketing scripts can’t run
Handling consent banners poorly — sometimes these trap focus or block input
On the flip side, cookies enabled might be slower if there’s:
Heavy script execution early in interaction flows
Complex segmentation or experiments evaluated on input events
Resolving unhealthy INP by cookies on/off
Go-to action plan to resolve an unhealthy INP by cookies on/off:
Ask Uxi to analyze your INP by cookies on/off values and suggest improvements.
Filter to isolate problem pages or components — especially dynamic ones.
Simulate INP of the suspected lens to see if fixing it will resolve the INP by cookies on/off. If yes, this is where the resolution focus should be.
Use an automated INP optimization tool like INProve to improve your INP by cookies on/off values.
Once you’ve improved INP, set an alert to be the first to know if it starts worsening again.
