What is technical SEO and why it matters
Technical SEO is the invisible infrastructure that supports rankings. You can have the best content, but if Google can’t crawl and render your site, that content stays invisible.
The 5 pillars of technical SEO
1. Crawlability and indexation
Ensure Googlebot reaches all important pages: correct robots.txt, updated XML sitemap, logical URL architecture.
2. Core Web Vitals
User experience metrics Google uses for ranking: LCP < 2.5s, INP < 200ms, CLS < 0.1.
3. JSON-LD Schema
The language to communicate with Google: Organization, Service, FAQPage, BreadcrumbList.
4. Hreflang for multilingual sites
Tell Google which version to show. Key rules: bidirectionality, x-default, canonical consistency.
5. Strategic internal linking
Silo architecture: hub pages linking to child pages with descriptive anchor text.
