15 AI Visibility Opportunities Detected

These technical gaps effectively "hide" Duffel - The best API to sell travel from modern search engines and AI agents.

Top 3 Blockers

  • !
    LLM-crawlable llms.txt
    Create an llms.txt file to guide AI crawlers to your most important, high-quality pages (docs, pricing, about, key guides). Keep it short, well-structured, and focused on authoritative URLs you want cited. Treat it as a curated “AI sitemap” that improves discovery and reduces the risk of crawlers prioritizing low-value pages.
  • !
    Is sitemap.xml exists?
    Maintain a sitemap.xml that includes your important canonical URLs and keeps last-modified dates accurate when content changes. Submit it in Search Console and ensure it is accessible to crawlers. A sitemap improves discovery of deeper pages and helps systems prioritize fresh, updated content.
  • !
    Structured data schema present
    Implement structured data wherever it matches the content (FAQPage, HowTo, Product, Organization, Article, BreadcrumbList). Schema gives machines a reliable map of your page and helps them extract facts correctly. Prioritize schema for your most valuable pages first, then expand site-wide after validation.

Top 3 Quick Wins

  • !
    List in public LLM indexes (e.g., Huggingface database, Poe Profiles)
    List your tools, datasets, docs, or brand pages on major AI/LLM discovery hubs where relevant (for example model/dataset repositories or app directories). These platforms add credibility signals (likes, forks, usage) and create additional crawlable references to your brand. Keep names, descriptions, and links consistent with your official website.
  • !
    Canonical tags are used properly
    Use canonical tags to define the preferred version of each page, especially when parameters, filters, or duplicate URLs exist. Canonicals prevent duplicate-content confusion and consolidate ranking signals. Verify canonical URLs return 200 status and point to the correct, indexable page.
  • !
    LLM-crawlable robots.txt
    Make sure your robots.txt allows crawling of important public pages and blocks only what should not be indexed (admin, internal search, duplicate parameter paths). If you use AI/LLM-specific crawler rules, document them clearly. After changes, test crawling with real bots/tools to confirm nothing critical is accidentally blocked.
