Technical SEO is the practice of optimizing a website's infrastructure to make it efficient for search engines to crawl, index and understand. It covers crawlability, indexability, sitemap engineering, robots.txt configuration, structured data, page speed, Core Web Vitals, mobile responsiveness, hreflang, canonicalization and JavaScript rendering. Technical SEO is the foundation that content and link-building strategies build on.
Crawlability and indexability (robots.txt, sitemap.xml, canonical URLs, meta robots tags). Page speed and Core Web Vitals (LCP, INP, CLS). Mobile-first indexing. Structured data (Schema.org JSON-LD). Internationalization (hreflang). Server-side rendering verification. Redirect chain hygiene. HTTPS and HSTS.
AI agents are technical SEO consumers too. The same structured data, fast TTFB and clean crawlability that win Google rankings also determine whether ChatGPT, Claude and Perplexity cite your content. Investments in technical SEO pay off across both surfaces.
