Homepage health for dental practices

Dentists sit near the all-niche loading rate (65.0% against 64.9%). Three groups matter for a practice owner: sites that load, sites whose domain is gone (14.8%) and sites behind bot walls (12.1%), which we could not read.

Structured data and AI access

Dental sites mark up more than the all-niche figures. The gap shows most on FAQPage (11.0% against 5.6% overall) and LocalBusiness-type schema (54.9% against 35.2%).

Two sites (2.4% of 82) disallow every crawler through a * rule, which also shuts out ChatGPT-User, OAI-SearchBot and PerplexityBot. That pattern may be a staging rule left on, but we cannot confirm intent.

Practical fixes for a dental practice

1. List every domain you pay forDead domains in our scan may belong to renamed or merged practices. Redirect old names to the live site.
2. Keep FAQ answers visible on the pageAdd FAQPage markup only for questions a patient can read on that page. Our dental website design pages show how we structure them.
3. Separate staging from live robots.txtCheck that no catch-all disallow rule made it to the live site. The AI visibility checker flags it in seconds.
4. Describe each location and each dentistUse one page per location with its own address and hours, and name the dentists. Dental SEO covers the rest.
5. Give llms.txt a cheap try19 of 82 sites (23.2%) serve one. If you add it, keep it short and accurate; the llms.txt generator writes a draft.

Appointment requests, insurance pages and patient data

Booking and insurance

People search for a dentist when something hurts or when a cleaning is due, and the booking route matters more than the story. Many practices pair the website with a scheduling tool from a practice-management vendor, for example an embedded widget.

Patient data

In the United States, forms and chat tools that collect health details can fall under HIPAA. In the UK and elsewhere, health data rules also apply. Ask your lawyer or professional body before adding a form, chat tool or tracking script.

Why schema matters here

A practice with several dentists, locations and services has a lot of facts to keep consistent. Schema gives each one a machine-readable home.

Method, margins and what we cannot see

Visibly broken covers a 404 homepage, broken SSL, a server error, a parked or for-sale page, a spam hijack, a default host page, a suspended account, a WordPress critical error or PHP errors on the page. Bot walls (401, 403, 429) are reported on their own line.

How much to trust a share: with 82 reachable sites the swing is up to about 11 points (95 percent confidence), and with 782 sites about 4 points. Only wide gaps to the all-niche figure deserve attention. Businesses with no website, or not on the list, are missing.

This is a picture of what sites publish on specific days. It does not measure citations in AI answers, leads, rankings or revenue, and it cannot explain why a site is set up as it is. Firewalls may refuse bots that robots.txt allows. Compare with the overall study, and browse the other niches.
