What is INP by browser auto-translate
INP by browser auto-translate shows how Interaction to Next Paint (INP) varies depending on whether the browser automatically translated the page content.
When auto-translation is applied, the page’s structure or text may change just after load, sometimes causing layout shifts or deferred hydration — both of which can delay interactivity.
Healthy INP by browser auto-translate sample
Should you worry
In a healthy experience:
Both translated and non-translated sessions show equally fast INP
The interaction layer (e.g. buttons, menus, inputs) remains responsive even after translation
Your JavaScript doesn’t block input readiness during or after translation
This means your site gracefully handles translation without compromising usability or delaying the first interaction.
Unhealthy INP by browser auto-translate sample
If translated INP is worse:
The browser may delay hydration until translated content is ready
Event listeners might not bind immediately due to DOM rewrites
Interactive elements (like buttons or tabs) may become janky or unresponsive during the transition
If non-translated INP is worse:
Your baseline experience may already be suffering from delayed hydration, blocking scripts, or heavy JavaScript
Resolving unhealthy INP by browser auto-translate
Go-to action plan to resolve an unhealthy INP by browser auto-translate:
Ask Uxi to analyze your INP by browser auto-translate values and suggest improvements.
Use Filters by device or route to spot patterns in translated interactions
Simulate INP of the suspected lens to see if fixing it will resolve the INP by browser auto-translate. If yes, this is where the resolution focus should be.
Use an automated INP optimization tool like INProve to improve your INP by browser auto-translate values.
Once you’ve improved INP, set an alert to be the first to know if it starts worsening again.
