Google Maps listing (reference, not scored)
What the clinic's public Google Maps listing showed when we read it: the rating other people gave, the number of their reviews and the hours the clinic itself publishes there. This block is a reference only — it does not enter the score, the rank, the ceilings or the holds, and we have not checked it beyond matching the listing to this record.

SEC | 16 | 2026-08-30 | |
| M3 | Basic medical licence Matched by the licence number the clinic itself publishes. Matched by licence number: the cedula published on the site returns the same physician in the register. [om] |

| M7 | Advertising honesty One or two soft superlatives or non-absolute safety promises. Lexicon scan of the clinic Portuguese pages: two soft unattributed claims on the about page and none elsewhere; no absolute safety or outcome statement. The terms page states that no content of the site is to be read as a promise or guarantee of a result. Pages loaded: home, /sobre-nos/, a physician profile page, /faqs/, the liposuction procedure page, /termos-e-condicoes/. [site-about] sempre com a melhor qualidade disponível |
SEC | 12 | 2026-09-20 | |
| M8 | Cross-locale consistency Could not verify — no points, counts against coverage, not a negative finding. Reason: Single language front. Last attempt: clinic_site, 17 September 2026 — one language front; no hreflang alternates or language links The clinic site publishes one language front; nothing to compare. |
? | ? | 5 | 2026-09-20 |
| M9 | Patient documents One. Pre-operative work-up and recovery information published in the FAQ; no consent form, revision policy or complaint route found. [site-faq] |

What we could not verify
- M8 · Cross-locale consistency — Single language front
These cells score nothing and are not negative findings. A cell on a register that is closed to machine queries is left out of the coverage calculation; the others count against it. Each one names why it is empty; an attempt that did not complete is re-run in the next collection pass. If you can point to a public source, send it.
