Guide: https://directindex.org/guides/structured-data-restaurant - **No list of services and prices found.** (+7 points) Agents answer 'what do they treat and what does it cost?' from directories instead.

Browsers and agents rank it lower or refuse it. - **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.
