How To Fix LCP Issue: Longer Than 4s (Desktop) and (Mobile)

Are you getting an error message on the google search console called “LCP issue: Longer than 4s (desktop) Or (Mobile)? You don’t need to worry now, I have come up with a solution for you. 

In May 2020, Google announced an algorithm update which was commonly called page experience algorithm update. This update included a new set of metrics, called the Core Web Vitals, which measured things like loading time, interactivity, and visual stability of a website. It was designed to give better rankings in Google’s search engine results pages (SERPs) to websites that provided a great experience to users.

Now it has already been fully integrated and started showing the effect on the ranking of pages in the SERP. They have added a block called “Core Web Vitals” in the google search console and webmasters can check their site’s score over there.

So, it is very important to fix this as soon as possible to maintain your ranking and get stable traffic from the search engine.

A good LCP score is 2.5 seconds or less.
