Performance is the Foundation of SEO
Google has officially declared that Core Web Vitals and page speed are primary ranking factors. Slow websites trigger high bounce rates, which communicate poor experience indicators to indexing crawlers.
We optimize backend PHP engines, minimize JavaScript sizes, and use caching networks to ensure Growth Stack pages load under 2 seconds.
Core Web Vitals to Watch:
- LCP (Largest Contentful Paint): Measures loading performance. Aim for 2.5 seconds or faster.
- FID (First Input Delay): Measures interactivity. Aim for 100 milliseconds or less.
- CLS (Cumulative Layout Shift): Measures visual stability. Aim for 0.1 or less.
Implement These Strategies
