Core Web Vitals: How Page Performance Impacts SEO and Conversions

Core Web Vitals: How Page Performance Impacts SEO and Conversions — Website Development article by Emirates ITS

Optimise LCP, FID, and CLS to improve Google rankings, user experience, and conversion rates on your website.

Performance is a ranking factor

Google Core Web Vitals measure real-world user experience: loading speed (LCP), interactivity (INP), and visual stability (CLS). Poor scores hurt search rankings and user engagement.

Studies consistently show that faster websites convert better — every second of delay increases bounce rates significantly.

Optimising Largest Contentful Paint

Optimise hero images, prioritise critical CSS, use CDN delivery, and implement lazy loading for below-fold content.

Server-side rendering and static generation reduce time-to-first-byte for content-heavy pages.

Interactivity and stability

Minimise JavaScript bundle sizes, defer non-critical scripts, and break long tasks to improve interactivity metrics.

Reserve space for images and ads to prevent layout shifts that frustrate users and fail CLS thresholds.

Monitoring and maintenance

Use Lighthouse, PageSpeed Insights, and Real User Monitoring to track performance continuously — not just before launch.

Performance optimisation is an ongoing discipline, not a one-time project.
