A text reader can quote only signals written as text or markup. In Citevio's October 2026 crawl of about 66,300 US dental websites, about 3.3% named an award in text, about 5.6% an AACD or American Dental Association membership, and at least 8.0% carried star-rating markup, which Google does not turn into stars for a practice's own reviews.
A badge that appears only as a logo gives a text reader nothing to quote or check. Written out, it can be quoted: "Named a 2025 Top Dentist by [name of the magazine]" says who chose the practice and when. In the crawl, few dental websites wrote awards or memberships out in the forms we searched for, and simple keyword counts make it look as if far more do.

What can an AI assistant read when it looks for trust signals on a dental website?
It can read the words on the page and the structured data in the page's code. This crawl read the same two layers: the visible text of up to five pages per website, and the JSON-LD structured data the server sends. An award shown only as an image, with no text beside it, was not counted, so every figure on this page describes a written claim. Schema.org, the shared vocabulary for structured data, has a field for each signal. Its award property is defined as An award won by or for this item.
Its memberOf property covers An Organization (or ProgramMembership) to which this Person or Organization belongs.
Its aggregateRating property is The overall rating, based on a collection of reviews or ratings, of the item.

How many US dental websites state an award or membership in readable text?
Few. Citevio's October 2026 crawl found an award or ranking named in readable text on 2,200 of 66,304 US dental websites (about 3.3%) and a professional membership on 3,739 (about 5.6%). We also counted press phrases such as "as seen on", but report no share for them: in a hand check, too many matches were not press mentions on a dental practice's website. Star-rating markup was more common: at least 5,312 of 66,284 websites (8.0%) carried AggregateRating and at least 1,614 (2.4%) carried Review markup.
| Signal | Websites | Share | Hand check (30 read) |
|---|---|---|---|
| Award or ranking named in text, such as a magazine's "Top Dentist" list or "Best of" a named place | 2,200 of 66,304 | about 3.3% | 27 named an award or ranking for a dental practice, 3 of them without saying who gave it (one quoted in a patient review); 1 was a ranking claim with no issuer; 1 was a website listing award programs; 1 was a home-care company's award |
| Professional membership in text: AACD, or member of the American Dental Association | 3,739 of 66,304 | about 5.6% | 27 stated a current membership |
AggregateRating markup | 5,312 of 66,284 | at least 8.0% | Markup field, counted by the crawler |
Review markup | 1,614 of 66,284 | at least 2.4% | Markup field, counted by the crawler |
Why do simple keyword counts overstate trust badges on dental websites?
Because the words that name badges also appear in ordinary sentences. The crawler's first, simple rule flagged websites for terms such as ADA, AACD, Top Dentist or Best of. When we read a random 30 of the flagged websites, 16 had no badge at all. The matches were an "ADA Accessibility Statement", which refers to the Americans with Disabilities Act, sentences such as "we follow ADA recommendations", phrases such as "best of all" and a patient's "the best of the best", a practice describing itself as one of the top dentists in its city, and a practice name that contains "Top Dentistry". The award and membership figures in the table come from stricter rules, checked by hand again. Of 20 websites the stricter rule dropped, 19 matched on words that were not a badge; the one miss was a press page listing a magazine's Top Dentists issue. Press phrases did not pass the same check: under the stricter rule, at most 22 of 30 matches were press mentions on a dental practice's website, and many of those were bare headings such as "In the News"; 4 were not about press, such as "photos featured in our gallery", and 4 were on websites that are not dental practices. We publish a share only when at least 27 of 30 hand-checked matches are right, so this page gives none for press.
Does star-rating markup make Google show stars for a dental practice?
Not for reviews of the practice on its own website. Google's review snippet guidelines say: If the entity that's being reviewed controls the reviews about itself, their pages that use LocalBusiness or any other type of Organization structured data are ineligible for star review feature.
The rule covers reviews placed through an embedded widget, such as a Google reviews widget. Google's FAQ on the change also says No, you don't need to remove them
, and that your Business Profile is not affected as this update only relates to organic Search
. In the crawl, at least 8.0% of dental websites carried AggregateRating markup. Whether AI assistants use that markup was not measured. In Citevio's June 2026 scan, Google star ratings did not distinguish practices named from those not named by ChatGPT or Perplexity, in a small, uneven sample; see do Google reviews affect ChatGPT.

How should a dental practice write its trust signals so they can be read and checked?
Write each one as a plain sentence a reader could verify. These steps make a claim readable; we did not test whether they change AI answers.
- Name the award fully. Give the issuer, the category and the year next to any logo: who chose the practice, for what, and when.
- Keep membership and credentials apart. Membership of an association is not the same as a credential it grants; for the AACD, see membership versus Accreditation.
- Name the outlet and date of a press mention, and link to the article, rather than a strip of outlet logos.
- Mark up only what the page says. If you add
awardormemberOfto structured data, Google's general guidelines apply:Don't mark up content that is not visible to readers of the page.
- Do not expect stars from your own reviews. Review markup about the practice on its own site does not produce Google review stars.

How were these trust signals counted?
Citevio's October 2026 crawl reached 66,410 US dental websites. For each, it read up to five pages (home, a cosmetic service page, a gallery, a press page and an about page) as served, without running scripts. Text signals were searched in the visible text. A first rule flagged badge and press words; a stricter second rule, applied to the flagged websites, kept an award only when "Top Dentist" or "Best of" sat next to award words such as a magazine, a year or "voted", and kept a membership only for the AACD or an explicit ADA membership. For each text signal we read a random 30 matching websites by hand and report a share only when at least 27 of the 30 were right. Structured data was read from JSON-LD only, so markup figures are lower bounds. Denominators differ slightly by signal because a website counts only where that signal could be read. The figures describe dental websites, which include some labs, vendors and agencies, not only practices. Our method for AI answers is described in how we measure AI visibility.
We wrote this page for dental practice owners deciding which credentials to show on their website and how. Citevio sells AI visibility work for dental practices.
Common questions
Does "ADA" on a dental website mean the American Dental Association?
Not always. Of 20 dental websites our stricter rule dropped, 10 had an "ADA" that was not a membership: 4 were notices under the Americans with Disabilities Act, such as an "ADA Compliance" link, 3 cited ADA guidance, 2 referred to an ADA-recognized specialty or board, and 1 was a bare "ADA" link. Write "member of the American Dental Association" if that is the claim.
Should a dental practice add AggregateRating markup to its website?
Not to get stars in Google. Google does not show review stars for a business's reviews about itself on its own pages, including reviews shown through a widget, and says existing markup does not need to be removed. Whether AI assistants use the markup was not measured.
Do AI assistants read award logos?
This crawl did not test it. It counted only written text and structured data. Writing the award out beside the logo, with the issuer and year, makes the claim readable either way.
