What is LCP by UTM source
LCP by UTM source shows the Largest Contentful Paint (LCP) value across different UTM sources (e.g. newsletter_april). This lens helps you identify which UTM sources deliver a slower experience for your users.
The list shows only UTM sources that generated traffic to your website during the selected period.
LCP is the most popular vital from the Core Web Vitals and represents the loading time of the largest element on the page.
Healthy LCP by UTM source sample
Should you worry
A healthy LCP by UTM source lens looks all green. Some UTM sources may be greener than others, but as long as there's no yellow or red, it’s considered healthy. The greener the UTM source, the better.
Unhealthy LCP by UTM source sample
In the example below, LCP by UTM source shows that newsletter_april has a slow LCP. This often leads to a higher bounce rate, more exits, and lower conversion rates.
Resolving unhealthy LCP by UTM source
Go-to action plan to resolve an unhealthy LCP by UTM source:
Ask Uxi to analyze your LCP by UTM source values and suggest improvements.
Use Filters to focus on the slow UTM source in your LCP by UTM source, then look across the other LCP lenses to find which ones show the slowest LCPs with the most pageviews.
Simulate LCP of the suspected lens to see if fixing it will resolve the slow LCP by UTM source. If yes, this is where the resolution focus should be.
Use an automated LCP optimization tool like Navigation AI to improve your LCP by UTM source values.
Once you’ve improved LCP, set an alert to be the first to know if it starts worsening again.
