About RankKing
RankKing is a Hong Kong digital-marketing company focused on the medical industry. We do one thing: help clinics and medical practices get found by patients in Google and AI search.
From chiropractic and orthopaedics to gynaecology and aesthetic medicine, we understand our clients' acquisition costs, advertising rules, and trust thresholds — and we build durable, compounding organic-traffic assets with SEO / AEO. We are a marketing team; we do not provide medical services or make any clinical claims.
What we believe
SEO content assets keep working for you
When ads stop, traffic stops — but SEO content assets keep working. Medical decisions hinge on trust: patients search, compare, and verify repeatedly. Showing up in those moments is the highest-quality acquisition channel there is.
How we work
Four capabilities, one method
SEO
Content, technical foundations, and keyword strategy that make your clinic easier for patients to find in Google's organic results.

AEO
Structured content and schema that optimise your site to work toward being cited as an answer source by ChatGPT, Google AI Overviews, and Perplexity.
- Structured FAQs and answer blocks
- Schema markup deployment
- Question-led content architecture
- Working toward featured snippets
GEO
E-E-A-T authority and entity consistency that help generative AI understand, trust, and reference your clinic — visibility for the AI era.

- Bilingual structure (TC + English)

Why medical only
Focus on one industry, do it properly
Specialty terminology, patient search intent, and medical advertising rules (such as the sensitive scope of the Undesirable Medical Advertisements Ordinance) all differ from other industries. Focusing on one industry sharpens our keyword research, content quality, and compliance awareness.
Why a specialist
How we differ from a general SEO agency
| How we differ from a general SEO agency | RankKing | A general SEO agency |
|---|---|---|
| Industry focus | Medical clinics only | Generalist, any industry |
| Scope | SEO + AEO + GEO | Mostly traditional SEO |
| On results | Transparent reports, no ranking promises | Often “ranking guarantees” |
| Medical compliance | Fluent in medical ad rules | May not be aware |
| Search coverage | Local SEO + AI citations too | Mostly Google ranking |
