Why Website Speed Matters in 2024
Google has made it clear: page speed is a ranking factor. Here’s why you should care:
1. SEO Rankings
Google’s Core Web Vitals are now part of their ranking algorithm. Sites with poor LCP, CLS, and INP scores may rank lower in search results.
2. User Experience
Slow sites frustrate users. A 1-second delay in page load time can result in:
- 7% reduction in conversions
- 11% fewer page views
- 16% decrease in customer satisfaction
3. Mobile-First Indexing
Google primarily uses the mobile version of your site for indexing. If your mobile speed is poor, your rankings suffer.
