Website loading speed has become one of the most critical factors in modern SEO. With Google officially incorporating Core Web Vitals into its ranking algorithm, slow websites risk losing visibility, traffic, and conversions.
Whether you target local or global markets, a fast-loading website is essential for user experience, SEO performance, and business growth.
In this comprehensive guide, PT Code Hero Indonesia explains how website speed impacts SEO, what Core Web Vitals are, and how to optimize your website effectively.
What Are Core Web Vitals?
Core Web Vitals are a set of user experience metrics defined by Google to measure real-world website performance.
- Largest Contentful Paint (LCP) – Loading performance
- First Input Delay (FID) – Interactivity
- Cumulative Layout Shift (CLS) – Visual stability
Recommended benchmarks:
- LCP: under 2.5 seconds
- FID: under 100 milliseconds
- CLS: under 0.1

Page speed is a confirmed ranking signal for both desktop and mobile search results.
2. Better User Experience
