Speed Is Money
Amazon found that every 100ms of latency costs them 1% in sales. For smaller businesses, the impact is even greater.
The Numbers Don't Lie
Bounce Rate Impact
A page that loads in 1 second has a 7% bounce rate. At 3 seconds, it jumps to 38%. At 5 seconds, it's 63%.
Conversion Impact
Every additional second of load time reduces conversions by 7%. That's money walking out the door.
SEO Impact
Google uses Core Web Vitals as ranking factors. A slow website literally ranks lower in search results.
How to Speed Up Your Website
Quick wins that make the biggest difference:
- Optimize images (use WebP format, lazy loading)
- Minimize CSS and JavaScript
- Use a CDN (Content Delivery Network)
- Choose fast hosting (Vercel, Netlify, Hetzner)
- Remove unnecessary plugins and scripts
Measuring Performance
Use Google PageSpeed Insights 和 Lighthouse to audit your website. Aim for a 90+ score on both mobile and desktop.
Speed is the most underrated feature of any website. It affects everything — user experience, SEO, conversions, and ultimately your bottom line.
Conclusion
Investing in speed is one of the highest-ROI improvements you can make. Start with image optimization and work your way through the list.
