# National Car Rental - Flughafen Frankfurt: Agent-Direct Score C (63.1%) Site: https://www.nationalcar.de/de/autovermietung-standorte/de/flughafen-frankfurt-g3nl.html?mcid=yext:245709 Report: https://directindex.org/r/nationalcar.de Scanned: 2026-10-20 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.) National Car Rental - Flughafen Frankfurt is partly visible to agents. Some AI assistants are turned away by National Car Rental - Flughafen Frankfurt's website. It can't find a menu or price list, so it answers from other sites. It finds a way to book or order directly on the site. ## Direct links - Book directly: https://www.nationalcar.de/de/reservieren.html (on the business's own site) - Phone: 06969715290 ## What to fix first ## What the site tells visitors (Measured, not scored) - **No English version declared.** Visitors from abroad, and assistants answering in English, read the page as it is. - **The server turns AI crawlers away at the door.** (+10 points) Requests as GPTBot (challenge:access denied), ClaudeBot (challenge:access denied), PerplexityBot (challenge:access denied) were refused, but a normal browser got the page. That's usually a bot list at the host or in a firewall that the owner never chose. Ask the host to allow these user agents. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing - **No tickets and prices found.** (+7 points) Agents answer 'what does it cost and when?' from marketplaces instead. Add a page with tickets, times and prices as text, and link to it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai - **Structured data is incomplete.** (+4 points) Missing: telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant - **No llms.txt.** (no points, but worth doing) Optional for now and cheap to add. It's a short text file that describes the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business ## Fix kit: What to paste Structured data (JSON-LD). Paste it as one block in the page's head, or in the builder's custom code box. Change anything that's wrong. ```html ``` llms.txt. Save as /llms.txt at the root of the site. ``` # National Car Rental - Flughafen Frankfurt > organization in Flughafen Terminal 1, 60549, Frankfurt Am Main, Frankfurt tours, attractions and museums.
