How to Improve Website Speed &
Core Web Vitals

Website speed is no longer just a technical metric — it is a direct ranking factor in Google's search algorithms and a crucial pillar of user conversion rates. Studies consistently show that page bounce rates increase by over 30% when load times increase from 1 second to 3 seconds.

1. Optimizing Largest Contentful Paint (LCP)

LCP measures the time it takes for the largest visual element (usually a hero image or main heading) to render on the user's screen. To achieve a good LCP score under 2.5 seconds:

• Use modern image formats like WebP or AVIF rather than uncompressed PNGs.
• Preload critical hero images using <link rel="preload" as="image">.
• Eliminate render-blocking CSS and JavaScript in the critical rendering path.

2. Minimizing Cumulative Layout Shift (CLS)

CLS measures visual stability. Unexpected layout shifts occur when images or elements load without pre-defined width and height dimensions:

• Always set explicit width and height attributes on image elements.
• Reserve space for dynamic banner ads or embedded widgets using CSS aspect ratios.
• Use CSS font-display: swap to avoid FOIT (Flash of Unstyled Text).

3. Enhancing Interaction to Next Paint (INP)

INP evaluates overall user responsiveness when clicking buttons or submitting forms. Reducing heavy JavaScript execution on the main browser thread is critical for smooth user experience.
