Core Web Vitals

A fast site keeps the customers it gets.

We cut your site's weight and improve LCP, CLS and INP so it loads fast on any connection, without giving up the design.

The three metrics Google measures

  • LCP — Largest Contentful Paint: how long the main visual element of the page takes to load.
  • CLS — Cumulative Layout Shift: how much the content jumps around while the page finishes loading.
  • INP — Interaction to Next Paint: how quickly the page responds when someone taps or clicks.

Common causes:

  • Uncompressed images weighing tens of megabytes
  • 3D models or video blocking the first load
  • JavaScript that delays the first interaction
  • Content that shifts while the page loads
  • A site that feels slow on mobile

Your site's weight decides whether the customer stays

Uncompressed images, heavy 3D models and unnecessary JavaScript can make a site take seconds to appear, and those seconds are enough for a potential customer to leave before reading a single line. You paid to bring them there; a slow page hands them to a competitor.

What we optimize

  • Image compression: conversion to WebP with tuned compression, keeping visual quality.
  • 3D model compression: lighter 3D models and assets, without losing visual fidelity.
  • Lazy loading: off-screen content loads only when the visitor scrolls to it.
  • Less render-blocking JavaScript: less code delaying the first render and the first interaction.

Case study: North Prime Graphics

  • Images: from more than 100 MB to about 1.3 MB, converted to optimized WebP.
  • 3D models: from about 65 MB to about 5.1 MB, compressed without losing fidelity.

How pricing works

The work depends on how many assets need optimizing and how complex your current code is, so we quote after looking at your site. You get a written proposal with a fixed price and a before-and-after measurement plan. We don't promise a specific PageSpeed Insights score; we show you your site's real numbers, before and after.

FAQ

01

What are LCP, CLS and INP?

They are Google's three Core Web Vitals. LCP measures how long the main visual element takes to load. CLS measures how much the content moves while loading. INP measures how quickly the page responds when someone interacts with it.

02

Why do Core Web Vitals matter?

They are a user-experience signal Google considers in its overall evaluation of a site, and they directly affect how many visitors leave before the page finishes loading. A slow site loses potential customers regardless of its ranking.

03

What gets optimized?

Image compression to WebP, 3D model compression when the site uses them, lazy loading of off-screen content, less render-blocking JavaScript and font optimization.

04

Will I get a perfect PageSpeed Insights score?

We don't promise a specific score: it depends on factors outside our control, like hosting or the visitor's network. What we deliver is a measurable reduction in site weight and load time.

05

How much does Core Web Vitals optimization cost?

It depends on the number of assets (images, 3D models, video) and the complexity of the current code. Send us your URL and you'll get a fixed price in writing after the 15-minute call.
