# Communitas: Agent-Direct Score D (43.8%)

Site: https://www.asta.uni-bremen.de/service/communitas/
Report: https://directindex.org/r/uni-bremen.de
Scanned: 2026-10-16 (Provisional: the assistant citation check still to come; the hatched part of the bar is not measured yet.)
Communitas is hard for agents to use.
Some AI assistants are turned away by the website of Communitas. It finds no 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.asta.uni-bremen.de/service/semesterticket/ (on the business's own site)

## What to fix first
- **No structured data for the business.** (+15 points) Add schema.org JSON-LD for the business (CafeOrCoffeeShop, BarOrPub or the closest type, with name, address, telephone and openingHoursSpecification, plus servesCuisine). It is the one block every assistant reads first; the fix kit below has it filled in. Guide: https://directindex.org/guides/structured-data-restaurant
- **No menu or price list found.** (+7 points) Agents answer 'what do they offer' from marketplaces instead. Add a menu or price list page and link it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **robots.txt blocks GPTBot, ClaudeBot, PerplexityBot, Google-Extended.** (+5 points) These are the crawlers behind ChatGPT, Claude, Perplexity and Google's AI features. Remove the Disallow lines for them, or add explicit Allow rules. Guide: https://directindex.org/guides/robots-txt-for-ai-agents
- **No llms.txt.** (no points, still worth doing) Optional today, cheap to add: a short text file describing the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business

## Fix kit: What to paste

Structured data (JSON-LD). One block in the page's head, or in the builder's custom-code slot. Replace anything that is wrong.
