Performance and SEO Connection


Website performance and SEO are closely connected.

Search engines prefer fast websites because they provide a better user experience.

Why Speed Matters for SEO

Slow websites frustrate users.

Search engines reduce rankings for pages that load too slowly.

User Experience Affects Rankings

Search engines measure how users interact with your site.

If users leave quickly, rankings can drop.

Core Web Vitals

Search engines use performance metrics such as:

  • Loading speed
  • Interactivity
  • Visual stability

HTML and Core Web Vitals

Clean HTML structure helps browsers render pages faster.

This improves important performance scores.

This improves both performance and accessibility, which benefits SEO.

Mobile Performance and SEO

Fast mobile performance is essential for ranking.

Avoid Heavy HTML for Better SEO

Large and messy HTML slows down crawling and rendering.

Clean markup helps search engines understand content faster.

Performance and Bounce Rate

If a page takes too long to load, users leave.

High bounce rate negatively affects SEO.

Companies care about traffic and visibility.

Developers who understand performance and SEO are highly valued.
