SpeedCurve | Mobile INP performance: The elephant in the room
February 7, 2024
However, after several months of discussing the impending change and getting a better look at INP issues in the wild, it’s hard to ignore the fact that mobile stands out as the biggest INP offender by a wide margin. This doesn’t get talked about as much as it should, so in this post we’ll explore:

- Working theories as to why mobile INP is so much poorer than desktop INP
- Correlating INP with user behavior and business metrics (like conversion rate)
- How you can track and improve INP for your pages
