AI-ready 5 of 5 critical checks passing · 3 of 4 important checks passing

Two crawler categories: AI live-retrieval crawlers fetch pages on demand to answer questions in ChatGPT, Perplexity or Claude; training crawlers feed model pre-training. Only the live-retrieval layer is graded here; the training tier is an editorial choice.

Critical: blocks AI visibility

  • AI live-retrieval crawlers allowed in robots.txt Your robots.txt must allow OAI-SearchBot, ChatGPT-User, PerplexityBot, Perplexity-User, Claude-User, and Claude-SearchBot. These fetch pages on demand to answer questions in ChatGPT, Perplexity, and Claude. Blocking any of them takes the brand's own pages out of the source pool for those answers; the brand can still be described from third-party pages.
  • No silent edge block on AI live-retrieval crawlers Even with robots.txt allowing them, the edge (Cloudflare, WAF, server) can still 403/429/503 AI bot user-agents. Most common culprit: Cloudflare's "Block AI Scrapers and Crawlers" managed rule, or Bot Fight Mode. Allow these UAs at a level above the WAF challenge rules.
  • HTTPS reachable on the homepage The homepage must be reachable over HTTPS without a redirect chain that fails. A TLS error is the one failure no crawler can work around, and retry behaviour is not documented for any of them.
  • Sitemap reachable A reachable sitemap helps AI crawlers discover internal pages beyond the homepage. We try /sitemap.xml, /sitemap_index.xml (Yoast), /wp-sitemap.xml (WordPress 5.5+), and any Sitemap: URL in robots.txt.
  • Homepage renders content without JavaScript Crawlers differ in whether they render JavaScript: OpenAI documents its fetchers as reading raw HTML, while Google-grounded answers ride a search index that does render. If the homepage is a SPA shell, the non-rendering crawlers see an empty div and have nothing to cite. Server-side rendering or pre-rendering makes the page readable to all of them; the check looks for at least 100 words and 1 heading without JS.

Important: improves capture

  • Canonical URL declared A canonical link tag tells crawlers which URL is the definitive version. Avoids citation fragmentation across www / non-www / trailing-slash variants.
  • Open Graph title and image set Open Graph title and image are what link-preview cards are built from across the web. Which AI surfaces use them, and where, is not documented per assistant; the cost of setting them is low enough that the check grades it anyway.
  • HSTS header advertised The Strict-Transport-Security header tells browsers to enforce HTTPS for future visits. Set in your web server config or via Plesk's HTTPS Strict Transport Security toggle.
  • No SPA, or a SPA with a meaningful noscript fallback When the homepage is a SPA, a noscript block with real fallback content (not just "please enable JavaScript") gives AI crawlers at least something to read. Best is server-side rendering; this is the half-measure.

Agent readiness: makes facts machine-readable

This check does not count towards AI visibility. It answers a different question: could software verify a fact about this brand without reading prose? On current evidence, structured markup does not make a brand cited more often in AI answers.

  • Organization or WebSite JSON-LD on the homepage Organization or WebSite JSON-LD on the homepage helps search engines recognize the brand as an entity (Knowledge Graph, rich results). Current evidence shows no direct effect on grounded-LLM citations; those models read the visible page text, not the JSON-LD. Still useful SERP hygiene; add via schema.org markup in the head.
