# Technical Foundations

Technical foundations are the checks that decide whether a page is even eligible to be ranked or cited: it must be reachable, return 200 over HTTPS, be indexable, render its content in the raw HTML, declare one canonical URL, sit in the XML sitemap and pass Core Web Vitals. Laurelin's 330-check register puts 100 of its checks in this pillar because no amount of content or authority work matters for a page a crawler cannot fetch. This hub links the technical audit service, the pillar-one audit checks, the IndexNow submitter and the graph tooling that maps a site's crawl structure.

## FAQ

### What is a technical SEO foundations audit?

A systematic pass over crawlability, indexation, rendering, canonicalisation, site speed, HTTPS, sitemaps and URL structure, each check tied to a documented Google or W3C source. Laurelin runs it as the first 100 checks of the 330-check AEO audit and reports every failing item with its severity, its evidence and the fix.

### Do AI crawlers follow the same rules as Googlebot?

Largely. GPTBot, ClaudeBot, PerplexityBot and Google-Extended obey robots.txt, fetch the raw HTML and mostly do not execute JavaScript, so server-rendered content, clean status codes and open robots rules matter more for AI search than for Google, not less.
