Site: https://sigmadentalclinic.com/
Report: https://directindex.org/r/sigmadentalclinic.com
Scanned: 2026-10-24 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.)
Sigma Dental Clinic is largely invisible to agents.
AI assistants can't open Sigma Dental Clinic's website, so they go by what other sites say about it.

## What to fix first
- **The site turns away every visitor that isn't a browser, AI agents included.** (+25 points) A plain fetch was refused (challenge:checking your browser). Only a real browser got the page. Every AI crawler and agent gets turned away the same way, so Reachable scores 0 and the rest is measured on the page as the browser rendered it. Ask the host to let the AI user agents through. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing
- **Appointments through an unrecognised third party.** (+9 points) Check that the provider keeps your business as the seller of record. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **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

## Already right
- **robots.txt lets AI crawlers in.** There's no robots.txt, which means everything is allowed.
- **Structured data found (Dentist).** address, phone, opening hours
