Common signs: "Poor" or "Needs improvement" URLs in Search Console, slow largest content and layout shifts. Usual causes: heavy images, blocking scripts and slow servers. What we do: fix LCP, INP and CLS in your code. What you get: passing Core Web Vitals.
Our Core Web Vitals fix moves your pages from "Poor" to "Good" in Google Search Console by fixing the causes of slow loading (LCP), slow interaction (INP) and layout shifts (CLS). A Codersarts engineer changes your code, not just plugin settings, and checks results against real-user data. Fixed price from $199 with 1-day delivery.

What Are Core Web Vitals?
Core Web Vitals are Google's three main measures of page experience: Largest Contentful Paint (LCP) for loading, with a good score at 2.5 seconds or less; Interaction to Next Paint (INP) for responsiveness, good at 200 milliseconds or less; and Cumulative Layout Shift (CLS) for visual stability, good at 0.1 or less. Google measures them from real Chrome users at the 75th percentile.
Lab tools such as Lighthouse help find problems, but Search Console's pass or fail is based on field data, which updates over about 28 days.

Example result (illustrative)
An e-commerce site on Next.js failed LCP and CLS on mobile product pages. The hero image loaded late and a cookie banner pushed content down. We preloaded and resized the hero image, served it in modern formats and reserved space for the banner. Lab LCP dropped from 4.8 to 1.9 seconds, and Search Console showed the templates as Good within a month.
