What is INP with adblocker on/off
INP with adblocker on/off shows the Interaction to Next Paint (INP) metric for sessions with and without ad blocking software. This lens helps you understand whether ads are slowing down how quickly users can interact with your site.
Ad scripts often consume main-thread time and can delay interaction responsiveness — especially when they inject DOM elements or trigger reflows. As a result, users without ad blockers may experience more input lag.
Only sessions with detectable ad blocker states during the selected timeframe are shown.
Healthy INP with adblocker on/off sample
Should you worry
If both groups (ad blocker on and off) show green INP values, your site handles third-party scripts gracefully without compromising interactivity.
Unhealthy INP with adblocker on/off sample
When INP is worse with ad blocker off, common causes include:
Input delay due to script-heavy ad components blocking the main thread
Third-party ad libraries competing for execution priority
Interaction handlers being delayed due to layout thrashing from injected ad content
If INP is worse with ad blocker on, it might be because:
Layouts collapse or reflow in the absence of ad elements, leading to visual jank
Your code assumes the presence of ad containers and fails to adjust when they're missing
Resolving unhealthy INP by US state
Go-to action plan to resolve an unhealthy INP by US state:
Ask Uxi to analyze your INP by US state values and suggest improvements.
Use Filters to find which pages, elements, or devices are most affected.
Simulate INP of the suspected lens to see if fixing it will resolve the INP by US state. If yes, this is where the resolution focus should be.
Use an automated INP optimization tool like INProve to improve your INP by US state values.
Once you’ve improved INP, set an alert to be the first to know if it starts worsening again.
