What Is Technical SEO and Why Is It Important?
Technical SEO covers optimizations that enable search engines to crawl, understand, and index your site. Even if you have the best content, you cannot rank high in search engines if your technical infrastructure is not solid. At BUZ Yazılım, we perform technical SEO optimization on sites for over 100 clients.
Site Speed Optimization
Google uses page speed as an important ranking factor. Core Web Vitals metrics are particularly critical:
Core Web Vitals
- LCP (Largest Contentful Paint): Loading of the largest content element — target: under 2.5 seconds
- INP (Interaction to Next Paint): Interaction response time — target: under 200ms
- CLS (Cumulative Layout Shift): Visual stability — target: under 0.1
Speed Improvement Steps
- Optimize images: WebP format, proper sizing, lazy loading
- CSS/JS minification: Minification and bundling
- Reduce server response time: TTFB optimization
- Use CDN: Serve content from the server closest to the user
- Browser caching: Configure Cache-Control headers
- Critical CSS: Serve above-the-fold styles inline
- Font optimization: font-display: swap and preload
Mobile-First Indexing
Google now indexes your site based on its mobile version.
Checklist
- Responsive design: Proper display across all devices
- Mobile-friendly content: Same content available on mobile as desktop
- Touch targets: Sufficient size and spacing (minimum 44x44px)
- Viewport meta tag: Properly configured viewport
- Font size: Readable text on mobile (minimum 16px)
- Pop-ups: Avoid intrusive pop-ups that block content
