वेबसाइट स्पीड टेस्ट — मुफ़्त ऑनलाइन

Under 2.5 seconds for LCP (Largest Contentful Paint) is Google's "Good" threshold. Under 1 second is excellent. Pages that take over 4 seconds lose significant users — 53% of mobile users abandon pages taking over 3 seconds.

TTFB measures how long from request to receiving the first byte of the server response. Under 200ms is good; under 800ms is acceptable. High TTFB indicates slow server processing, database queries, or geographic distance from the user.

Google's Core Web Vitals are three user experience metrics: LCP (Largest Contentful Paint — loading), INP (Interaction to Next Paint — interactivity), and CLS (Cumulative Layout Shift — visual stability). Good scores positively affect Google search rankings.

PSI runs in a simulated Lighthouse environment with throttled connection. This tool measures real server response from our infrastructure. Results vary by test location, time of day, and server load. Use PSI for standardised benchmarking.

Top improvements: use a CDN, enable server-side compression (gzip/brotli), optimize and lazy-load images, minify CSS/JS, reduce server response time (upgrade hosting), eliminate render-blocking resources, and leverage browser caching.
