What is INP by UTM Source
INP by UTM Source shows the Interaction to Next Paint (INP) value across different UTM sources (e.g., newsletter_may). This lens helps you identify which traffic sources are associated with slower user interactions and input responsiveness.
The list includes only UTM sources that generated traffic to your website during the selected period.
INP is a Core Web Vital that captures how responsive your site feels. It measures the latency of all interactions on a page and reports the worst one. A slow INP means users experience lag when clicking, tapping, or typing - especially frustrating for mobile users.
Healthy INP by UTM Source sample
Should you worry
A healthy INP by UTM source lens looks all green. Some UTM sources may show slightly better interaction performance than others, but as long as there’s no yellow or red, it’s considered healthy. The greener the UTM source, the snappier the experience.
Unhealthy INP by UTM Source sample
In the example below, INP by UTM source shows that the powered_by_ campaign leads to sluggish interactions. This often happens if the landing page is overloaded with scripts or if users come from low-end devices.
Resolving unhealthy INP by UTM Source
Go-to action plan to resolve an unhealthy INP by UTM Source:
Ask Uxi to analyze your INP by UTM Source values and suggest improvements.
Use Filters to isolate the slow UTM source in INP by UTM source, then review other INP lenses like page, device, or country to discover underlying causes.
Simulate INP of the suspected lens to see if fixing it will resolve the INP by UTM Source. If yes, this is where the resolution focus should be.
Use an automated INP optimization tool like INProve to improve your INP by UTM Source values.
Once you’ve improved INP, set an alert to be the first to know if it starts worsening again.
