Core Web Vitals 2026: What You Need to Fix Right Now to Rank on Google
Google's Core Web Vitals are now a direct ranking factor. This guide explains LCP, INP, and CLS in plain English, and gives you a prioritized action list to improve your scores.
Introduction
In 2026, Google values search user experience above all else. Slow pages lead to higher bounce rates and worse ranking. This guide explains the core speed metrics Google measures and how to optimize them.
1. Largest Contentful Paint (LCP)
LCP measures loading performance. To provide a good user experience, LCP should occur within 2.5 seconds of when the page first starts loading. Optimize this by self-hosting fonts, compressing images to WebP/AVIF, and eliminating layout blocking CSS/JS.
2. Interaction to Next Paint (INP)
INP replaced FID as the responsiveness metric. It measures how fast a page responds when a user clicks or taps an element. Avoid heavy JS scripts running on the main thread to keep your INP below 200 milliseconds.
