The Cost of Slow Websites
Every second counts. Studies show that a 1-second delay in page load time can result in a 7% reduction in conversions. For an e-commerce site making $100,000 per day, that's potentially $7,000 in lost revenue daily.
Core Web Vitals: Google's Performance Metrics
Google now uses Core Web Vitals as a ranking factor. These include:
- LCP (Largest Contentful Paint): How fast does the main content load?
- FID (First Input Delay): How quickly can users interact?
- CLS (Cumulative Layout Shift): How stable is the visual experience?
Practical Steps to Improve Performance
- Optimize images: Use modern formats like WebP and implement lazy loading
- Minimize JavaScript: Split bundles and defer non-critical scripts
- Leverage caching: Implement proper cache headers and CDN strategies
- Reduce server response time: Optimize backend queries and use edge computing
The Business Impact
Fast websites don't just rank better—they convert better. Users trust fast experiences, and that trust translates directly into revenue.
