Technical SEO for AI Websites: Crawlability, Canonicals and Sitemaps
Good technical SEO makes it easy for search engines to understand what exists, what matters and which URL is canonical.
Start with one canonical URL
Pick the exact site URL you want indexed and use it consistently in canonical tags, Open Graph URLs, structured data and sitemap entries. Mixed hostnames or protocol variants create needless ambiguity.
Robots.txt is about crawling, not indexing
Use robots.txt to control crawler access to paths you truly do not want crawled. Do not use it as a substitute for noindex. A page blocked from crawling cannot reliably communicate its indexing directive.
Your sitemap should contain canonical pages
List only the URLs you want search engines to discover. Keep the sitemap at a stable URL, return valid XML with a successful HTTP response and include the exact canonical URLs used by the site.
Internal links create discoverability
Important pages should be linked from other relevant pages using descriptive anchor text. A page that exists in a sitemap but is disconnected from the rest of the site is harder for both crawlers and users to understand.
Use Search Console to separate problems
URL inspection answers whether a specific page is indexed. The sitemap report answers whether Google can read your sitemap and what it discovered from it. Page indexing reports can lag, so do not confuse a delayed report with a broken page.
AI sites need the same fundamentals
Whether your content is about LLMs, agents or AI SEO, the technical rules are unchanged: fast HTML, stable URLs, useful internal linking, correct canonical tags, valid structured data and a sitemap that reflects the pages you actually want indexed.
