# Once in Brussels: Agent-Direct Score D (47.7%) Site: http://www.onceinbrussels.be Report: https://directindex.org/r/onceinbrussels.be Scanned: 2026-10-18 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.) Once in Brussels is hard for agents to use. An AI assistant can open Once in Brussels's website. It can't find a menu or price list, so it answers from other sites. It can't find a link to book or order online. ## Direct links - Phone: 02 850 60 90 ## What to fix first - Languages: English, French, Dutch - **No ticket link on the website.** (+15 points) There's no link on the site for an agent to follow. If you take bookings or orders through a platform, link to it from the site so agents can find it. Add a ticket or booking page on your own domain. Guide: https://directindex.org/guides/book-direct-on-your-own-website - **Structured data is incomplete.** (+7 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant - **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 - **Almost no text without JavaScript.** (+2 points) Crawlers that don't run scripts see an empty page. Put the menu, hours and address in plain HTML. Guide: https://directindex.org/guides/website-blank-without-javascript - **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. ``` # Once in Brussels > person in Rue des Tanneurs 62, 1000, Brussels tours, attractions and museums.
