Performance Optimization for SEO

Speed is a ranking factor. Optimize images, code, and delivery to improve Core Web Vitals.

Load time impact on SEO

A page that loads in 1 second vs. 3 seconds has a 40% difference in bounce rate. Google penalizes slow sites by lowering rankings. Aim for LCP under 2.5 seconds.

Optimization checklist

Minify CSS/JS, compress images, enable GZIP, use a CDN, lazy load images, defer non-critical CSS, and minimize HTTP requests. Each optimization compound: a 20% improvement here + 20% there = 40% total improvement.
