Google's Core Web Vitals measure how real users experience your site speed and stability. They influence SEO and — more importantly — whether visitors stay long enough to enquire.

LCP — Largest Contentful Paint

How fast the main content appears. Usually your hero image or headline block. If it takes more than ~2.5 seconds, users bounce — especially on mobile data.

Fixes: compress hero images, use modern formats (WebP), reduce server response time, avoid massive sliders above the fold.

INP — Interaction to Next Paint

How responsive the page feels when users tap or click. Slow JavaScript, heavy plugins or bloated themes cause laggy menus and forms.

Fixes: audit third-party scripts, defer non-critical JS, simplify animations on mobile.

CLS — Cumulative Layout Shift

Does the page jump while loading? Buttons moving when ads or fonts load frustrate users and cause mis-taps.

Fixes: set width/height on images, reserve space for embeds, load fonts efficiently.

What to tell your developer or agency

• Run PageSpeed Insights on homepage and top service pages
• Prioritise mobile results — that's where most Indian users browse
• Fix LCP first (biggest visual impact), then CLS, then INP

You don't need to become a performance engineer. You need a site that loads confidently on a mid-range phone — because that's how your next client is browsing you right now.
