The three metrics that matter
Largest Contentful Paint (LCP) measures how long the main content takes to load — aim for under 2.5 seconds. Interaction to Next Paint (INP) measures responsiveness to clicks and taps. Cumulative Layout Shift (CLS) measures visual stability — how much elements jump around as the page loads.
Common causes of slow sites
Unoptimized images are the single biggest culprit, followed by bloated page-builder themes, render-blocking scripts, and third-party embeds (chat widgets, tracking pixels, video players) loaded before they're needed.
Fixes that make the biggest difference
Compress and resize images
Serve images in modern formats (WebP or AVIF) at the exact size they'll display, not full resolution scaled down by CSS.
Defer non-critical JavaScript
Load chat widgets, analytics, and other third-party scripts after the main content renders, not before.
Reduce plugin and page-builder bloat
Every plugin adds code your browser has to download and parse. Audit and remove anything not actively earning its place.
Reserve space for images and ads
Set explicit width and height attributes so the browser reserves space before the image loads, preventing layout shift.
Use a CDN and enable caching
A content delivery network reduces the physical distance data travels, and proper caching headers mean returning visitors load pages instantly.
How to check your score
Run your site through Google's PageSpeed Insights or Search Console's Core Web Vitals report to see real-user data, not just lab simulations.
The bottom line
Speed isn't a one-time fix — it's a maintenance habit. If your site hasn't been audited recently, request a free technical SEO audit and we'll show you exactly what's slowing you down.
