Here’s a breakdown of how each type performs in key SEO areas that matter today.

(A) Page Speed & Core Web Vitals

Speed is still one of Google’s strongest ranking factors.

Static Websites

(Excellent)

Static websites load incredibly fast because:

• No server-side processing
• No database queries
• Content is delivered instantly

Result:
Static sites often achieve near-perfect Core Web Vitals scores, improving rankings and user experience.

Dynamic Websites

(Moderate)

Dynamic websites may slow down due to:

• Database lookups
• Heavy CMS plugins
• Server-side code execution

However, modern caching, CDNs, and headless CMS frameworks can dramatically improve speed.
