Scanned: 2026-10-23 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.)
Mark Gray DDS Cosmetic and Family Dentistry is partly visible to agents.
An AI assistant can open Mark Gray DDS Cosmetic and Family Dentistry's website. It can't find a menu or price list, so it answers from other sites. It finds a way to book or order directly, through NexHealth.

## What to fix first
- **No structured data for the business.** (+14 points) Add schema.org JSON-LD for the business (Dentist, MedicalClinic, Physiotherapy or the closest type, with name, address, telephone and openingHoursSpecification). Every assistant reads this block first, and the fix kit below has it filled in. 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. Add a page that lists services and prices as text, 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
- **The phone number on the site doesn't match the open map data.** The site shows 281-493-9395, but OpenStreetMap or Overture Maps lists +12816569573. An assistant that sees two numbers can't tell which one to trust. Fix whichever is wrong, on the site or in the map data at openstreetmap.org.

## 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.
