Change History
| Date | Change |
|---|---|
| 2026-10-02 | Other review platforms checked on 2026-10-02: the clinic is listed on vrisko.gr with its telephone and an add-review form (no reviews yet), so presence on other review platforms is recorded. |
| 2026-09-29 | Corrected 2026-09-29: review recency within 3 months (newest review dated 2026-09-21); owner replies to reviews confirmed on the Google listing (owner reply dated 2026-05-23). |
| 2026-09-29 | Corrected 2026-09-29: the website address patrasdentists.gr, which no longer exists (the domain was not found in a DNS lookup), was removed from the contact details. |
| 2026-09-17 | Re-read on 2026-09-17: the clinic's Google listing. Corrected: the listed website domain (patrasdentists.gr) is confirmed non-existent today, not merely unreachable -- a public DNS-over-HTTPS lookup returns NXDOMAIN for both A and NS records, so no website is recorded rather than an unresolving one. Recorded: evening hours to 21:00 on three weekdays; Google 4.9 from 77 reviews, no recurring-complaint or manipulation pattern in the histogram; no owner replies visible on the readable sample; no usable listing photo at this check. Price criteria and structured-data/service-page criteria recorded as absent because no website resolves and the Google listing carries no price list. Still unverified: most infrastructure and communication facts -- and other review platforms. |
| 2026-08-27 | Initial data collection for the Greece national index: verified via Google Maps; the listed website domain (patrasdentists.gr) failed to resolve during verification. O.S. Achaias registry site also found unreachable. |
