## What to fix first
- **No way to book an appointment online.** (+15 points) Agents have nothing to act on. Add an online appointment page on your own domain. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **The server turns AI crawlers away at the door.** (+10 points) Live fetches as GPTBot (cloudflare_challenge), ClaudeBot (cloudflare_challenge), PerplexityBot (cloudflare_challenge) were refused while a normal browser got the page. This is usually a hosting or firewall bot list the owner never chose. Ask the host to allow these user agents. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing
- **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 with services and prices as text and link it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **Structured data is incomplete.** (+3 points) Missing: opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **No llms.txt.** (no points, still worth doing) Optional today, cheap to add: a short text file describing the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business

## 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.

```html
<script type="application/ld+json">
