Scanned: 2026-10-16 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.)
Colombella is mostly ready for agents.
An AI assistant can open Colombella's website. It can't find a menu or price list, so it answers from other sites. To book or order, it is sent to OpenTable, a marketplace.

## What to fix first
- **Booking only through opentable.** (+12 points) Every transaction an agent makes goes through the marketplace, which takes its commission. Add a direct way on your own site. Even a simple form will do. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **Ordering only through ubereats.** (+12 points) Every transaction an agent makes goes through the marketplace, which takes its commission. Add a direct way on your own site. Even a simple form will do. Guide: https://directindex.org/guides/online-ordering-without-delivery-apps
- **No menu or price list found.** (+7 points) Agents answer 'what do they offer?' from marketplaces instead. Add a page with the menu or price list and link to it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **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

## 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. In Düsseldorf, 21% of comparable sites declare one.

## Fix kit: What to paste

llms.txt. Save as /llms.txt at the root of the site.

## Already right
- **robots.txt lets AI crawlers in.** No rule blocks the main AI user agents.
- **AI crawlers get the page.** GPTBot, ClaudeBot and PerplexityBot all got a normal response.
- **Structured data found (Restaurant).** address, phone, opening hours
- **OpenTable works with agents through its partners.** OpenTable's terms page could not be fetched on 2026-10-15; OpenTable names over 200 authorized partners, Google, Meta and OpenAI among them, as the channels through which agents book. Terms read on 2026-10-15: https://mynews13.com/fl/orlando/business/2026/07/14/opentable-new-terms. An assistant that isn't a partner may not be able to finish there. A direct path on your own domain works for all of them.
