How We Score Each Agency
Every agency in the main list is based in Niigata. National dental agencies that work here are shown separately below it. We checked each one’s dental client work, public reviews, published results and terms before adding it, then read every client testimonial we could find. Only agencies that pass these checks are listed, so every DSA Score starts at 80. The other 20 depend on how many of the 100 points below each agency earns: DSA Score = 80 + points earned ÷ 5.
- Profile (up to 80 points). Five factors scored out of 20 each, then scaled to 80:
- Client reviews: a verified rating on Google, Clutch, G2, UpCity, Trustpilot or a similar platform
- Experience: years in business, a named founder or leader, and a dental or healthcare focus
- Client portfolio: how many dental clients the agency names publicly
- Published results: case studies with real figures, such as traffic, leads or revenue
- Transparency: published prices, clear contract terms, and a confirmed website and location
- Client feedback (up to 20 points). What clients actually say, from the testimonials we read on Google, independent review sites and the agency’s own website:
- Independent reviews (6): how many reviews we found that the agency doesn’t control
- Client satisfaction (8): how consistently clients praise the agency, adjusted so a handful of reviews can’t outscore a long track record
- Independent sources (4): how much of the feedback comes from Google and review sites rather than the agency’s own pages
- Dental clients (2): at least one review from a dental practice
- Verification. Client feedback points are reduced when reviews or agency details can’t be verified.
We summarise each client review in our own words and link to the original, so you can read it in full.
Price ranges are a guide based on published rates and typical fees for agencies of a similar profile. Always ask for a written quote.
