Technical SEO: The Technical Foundation for Visibility

Technical SEO covers all server-side and infrastructure measures that enable search engines and AI systems to access your content. Without a clean technical foundation, even the best content cannot be indexed or cited.

Core areas:

• Crawlability: robots.txt, XML sitemaps, crawl budget optimisation — so search engines and AI crawlers capture your pages efficiently.
• Indexability: Canonical tags, hreflang, duplicate content management — so each page is uniquely identifiable.
• Page speed: Core Web Vitals (LCP, INP, CLS), server response time, image optimisation — so users and bots do not bounce.
• Security & architecture: HTTPS, clean URL structures, internal linking, breadcrumbs — so site structure is logical and traceable.

Relevance for AI visibility: AI crawlers such as GPTBot, ClaudeBot and PerplexityBot evaluate technical signals similarly to Googlebot. A technically flawless website is crawled more frequently and classified as a reliable source. In the CAFE framework, Technical SEO forms the foundation on which entity architecture and GEO measures are built.
