How to optimize whatsapp.com
The redirect from whatsapp.com to www.whatsapp.com adds 780ms delay to both LCP and FCP.
Configure your server to serve www.whatsapp.com directly without redirecting. Update all internal links and canonical URLs to point to the final destination. Set up proper DNS records to avoid the redirect entirely.
A score of 74 falls in the "Needs Improvement" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.

Measures visual stability - how much content shifts during page load
The WhatsApp website has below-average performance with a score of 74/100, primarily hampered by inefficient resource loading and multiple technical issues. The biggest problem is a critical redirect that wastes 780ms before the page even starts loading, combined with render-blocking resources that delay First Contentful Paint by nearly 2 seconds. The site is also loading 316KB of unused JavaScript and suffers from poor font loading strategies, resulting in a sluggish 7.2-second Time to Interactive. Eliminating the redirect, deferring non-critical JavaScript, and optimizing the font display could easily boost the performance score by 15-20 points and dramatically improve user experience.
Why It Matters:
CSS and JavaScript files are blocking initial page render for 1,920ms, severely delaying FCP.
How to Fix:
Add 'defer' attribute to non-critical JavaScript files like dXAv7EHn9XG.js. Use media queries or 'preload' with 'onload' for non-critical CSS files. Inline critical CSS directly in the HTML head to render above-the-fold content immediately.
Why It Matters:
Over 316KB of unused JavaScript is loaded, wasting bandwidth and blocking the main thread.
How to Fix:
Use code splitting to load only necessary JavaScript per page. Remove unused polyfills for modern Array and Object methods since most browsers support them natively. Implement tree-shaking in your build process to eliminate dead code automatically.
Once your site is optimized, maintain that speed. Use DeployHQ for zero-downtime, automated deployments—so performance fixes and updates go live safely every time, without breaking your site.
