Here’s a fast list of common reasons why AI can’t “see” your site (or a specific page), even if it works fine in your browser:

🔒 1. 500 Internal Server Error

  • What happens: The server fails before the page is delivered.
  • Effect: AI can’t retrieve any content.
  • Common causes: Firewall rules, resource exhaustion, broken plugins, .htaccess errors.

🚫 2. 403 Forbidden Error

  • What happens: The server actively denies access.
  • Effect: AI gets locked out, even though the page may be up for normal users.
  • Common causes: Security plugins, IP blocking, geo-blocking, bot protection.

🔄 3. Too Many Redirects / Broken Redirect Chains (3xx loops)

  • What happens: The page redirects too many times or goes in a loop.
  • Effect: AI gives up before reaching the final content.
  • Common causes: Misconfigured redirects, .htaccess issues, conflicting plugins.

⛔ 4. Noindex Tag or X-Robots-Tag

  • What happens: The page includes a tag that tells bots not to index it.
  • Effect: Some AI systems obey that and skip it entirely.
  • Common causes: SEO plugin misconfigurations or deliberate privacy settings.

🌐 5. Blocked by robots.txt

  • What happens: The robots.txt file tells bots not to crawl a page or section.
  • Effect: Compliant crawlers (including some AI tools) will avoid it.
  • Common causes: Overly strict robots.txt rules.

🌍 6. DNS or Network Issues

  • What happens: The domain fails to resolve or load due to DNS propagation, expired domain, or slow server response.
  • Effect: AI can’t even initiate the connection.
  • Common causes: Hosting issues, expired domains, wrong nameservers.

🧱 7. CAPTCHA, JavaScript Walls, or Bot Challenges

  • What happens: The page requires JavaScript to render or triggers anti-bot challenges.
  • Effect: AI can’t solve them, so it sees nothing.
  • Common causes: Cloudflare protection, JS-based rendering frameworks, CAPTCHA.

📉 8. Page Takes Too Long to Load (Timeouts)

  • What happens: If a server takes too long to respond, AI crawlers may time out.
  • Effect: Partial or no content is retrieved.
  • Common causes: Slow servers, heavy scripts, unoptimized images.
