You have a beautiful site. Tidy, well-designed. But it takes 5 seconds to load. While your visitors leave, your competitors with a 1-second site are grabbing your customers.
The real business equation
Google published the study: every additional second of loading time drops your conversions by 7%. A 3-second site instead of 1 second costs you 14% of revenue. Over a year, that’s a month of lost income.
The 4 levers that change everything
1. Hosting
Cheap shared hosting kills everything. Moving to Vercel or a dedicated VPS often cuts loading time by 3.
2. Images
WebP or AVIF, lazy loading, proper sizing. A 2MB JPEG becomes 200KB in WebP with no visible loss.
3. JavaScript
WordPress sites with 25 active plugins average 4MB of JS to download. Next.js sites average 300KB. Enough said.
4. Caching
Edge cache, CDN, ISR. A static page served from the CDN loads in 50ms anywhere in the world.
