In 2021, Google officially made Core Web Vitals part of its ranking algorithm. Three years later, most Dubai business websites still fail these metrics — and are losing valuable search visibility as a result. Understanding and improving these scores is one of the highest-ROI SEO investments you can make in 2025.
What Are Core Web Vitals?
Core Web Vitals are a set of specific performance metrics Google uses to measure real-world user experience on your website. They focus on three dimensions: loading performance, interactivity, and visual stability.
The Three Metrics That Matter
1. Largest Contentful Paint (LCP) — Loading Performance
LCP measures the time it takes for the largest visible element on your page — usually a hero image or heading — to fully load. Google considers anything under 2.5 seconds a good score. Above 4 seconds is poor. For most Dubai business websites, the primary culprit is unoptimised hero images. Compressing images to WebP format, using lazy loading for off-screen content, and removing render-blocking scripts typically improve LCP scores by 40-60%.
2. Interaction to Next Paint (INP) — Responsiveness
INP replaced First Input Delay (FID) in March 2024. It measures how quickly your page responds to all user interactions throughout their visit — clicks, taps, and keyboard input. A score under 200 milliseconds is considered good. Heavy JavaScript bundles, excessive third-party scripts, and poorly optimised animations are the main causes of poor INP scores.
3. Cumulative Layout Shift (CLS) — Visual Stability
CLS measures unexpected movement of visible page content. A layout shift happens when an image, advertisement, or dynamically loaded element suddenly appears or moves, pushing content the user was reading or about to click. This is frustrating and leads to accidental taps. A score under 0.1 is good. The fix is almost always adding explicit width and height attributes to images and reserving space for dynamic content.
How to Measure Your Core Web Vitals
Use Google Search Console — the field data under the Core Web Vitals report shows your real user performance. PageSpeed Insights provides both lab and field data for any specific URL. Lighthouse in Chrome DevTools gives actionable recommendations for improvements.
Prioritise for Business Impact
If your website sells services or generates leads, start with LCP and CLS fixes — these typically require the least development effort and deliver the most visible improvement. INP optimisation is more complex but becomes critical for content-heavy or interactive sites. A website that passes all three Core Web Vitals consistently adds a meaningful ranking advantage in local Dubai search results.
