What is Technical SEO?

Technical SEO refers to optimizing your website's infrastructure to help search engines crawl and index your content effectively.

Core Web Vitals

Google's Core Web Vitals are critical ranking factors:

First Input Delay (FID)

  • Measures interactivity
  • Target: Under 100 milliseconds

Cumulative Layout Shift (CLS)

  • Measures visual stability
  • Target: Under 0.1

Site Speed Optimization

Speed is crucial for both users and search engines:

  1. Optimize Images: Use modern formats like WebP
  2. Minimize JavaScript: Remove unused code
  3. Enable Compression: Gzip or Brotli
  4. Use CDN: Distribute content globally

Structured Data

Implement schema markup to help search engines understand your content:

  • Organization schema
  • Product schema
  • Article schema
  • FAQ schema

Mobile-First Indexing

Ensure your site works perfectly on mobile devices:

  • Responsive design
  • Touch-friendly navigation
  • Fast mobile load times
