Technical SEO is the backbone of modern website ranking.
Even if you write great content, your website won’t rank unless Google can:

• Crawl it
• Index it
• Understand it
• Trust its structure
• Load it fast

If you’re a developer, you already have the skills needed to master Technical SEO — you just need the right checklist.

⭐ What Is Technical SEO? Link to heading

Technical SEO refers to the optimizations that improve how search engines crawl and index your website.

This includes:

• Core Web Vitals
• Mobile responsiveness
• Sitemap optimization
• Canonical tags
• Structured data
• Redirects
• Server & hosting configuration
• Security (HTTPS, HSTS, CSP)

Because developers control:

• Build tools (Hugo, React, Next.js, Vue, Svelte, etc.)

Your code determines your ranking more than your content.
