# Serpent à Plume: Agent-Direct Score D (50.8%)

Site: https://serpentaplume.com/
Report: https://directindex.org/r/serpentaplume.com
Scanned: 2026-10-15 (Provisional: the action test and the assistant citation check still to come; the hatched part of the bar is not measured yet.)
Serpent à Plume is hard for agents to use.
An AI assistant can open the website of Serpent à Plume. It can read what Serpent à Plume offers. It finds no link to book or order online, only a phone number.

## Direct links
- Menu: https://serpentaplume.com/pages/menu
- Phone: +33 140099690

## What to fix first
- **No structured data for the business.** (+14 points) Add schema.org JSON-LD for the business (Restaurant, LocalBusiness or the closest type, with name, address, telephone and openingHoursSpecification, plus servesCuisine and acceptsReservations). 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 booking or ordering link on the website.** (+13 points) Only a phone number or WhatsApp, which agents cannot use yet. If you take bookings or orders through a platform, link to it from the site so an agent can find it. Add a booking or ordering page. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **Almost no text without JavaScript.** (+2 points) Crawlers that do not run scripts see an empty page. Render the menu, hours and address as plain HTML. Guide: https://directindex.org/guides/website-blank-without-javascript

## 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.
