== Frequently Asked Questions ==

= <strong>Why is website speed so critical for success?</strong> =
Site speed is no longer just a convenience—it's essential for SEO, user experience, and conversions. Google ranks faster sites higher, visitors abandon slow sites (53% leave if loading takes over 3 seconds), and conversion rates drop approximately 4.42% with each second of load time. LWS Optimize addresses all these issues with professional-grade optimization.

LWS Optimize works on any WordPress installation regardless of host. However, when paired with LWS hosting, you'll unlock additional server-level optimizations like enhanced Varnish cache.
