What Halcy is
Healthcare SEO and AI visibility service
Halcy is a healthcare marketing service that builds search and AI visibility for medical practices. We structure a practice's medical expertise as entity-based content that search engines and large language models can understand, cite, and recommend.
Who it’s for
Healthcare practices that want patients to find them on Google and in AI search tools like ChatGPT, Google AI Overviews, and Perplexity.
What problem it solves
Great healthcare providers are often invisible online. Patients searching for care find competitors instead. AI assistants recommend other practices because they have no structured data about yours.
What it replaces
SEO agencies, freelance content writers, and manual schema markup. Instead of blog posts and keyword reports, Halcy deploys structured medical content with entity-based SEO and ongoing AI visibility monitoring.
What makes it different
Entity-first architecture. Your practice is structured as a medical entity with defined relationships to conditions, treatments, and specialties. This is what AI systems need to cite you as a source, not just mention you as a result.
How it works
Live in one day.
Audit your visibility
We analyze where you appear today in Google and AI answers, and identify the gaps. This includes indexation status, schema markup, structured data, and AI citation presence.
Build your presence
We create structured medical content for every service and condition you treat. Each page includes JSON-LD schema markup, evidence-based content, and entity relationships that search engines and AI systems can parse.
Monitor and improve
We track Google rankings, indexation rates, and AI citation frequency weekly. You get reports. We handle the ongoing optimization as search algorithms evolve.

Founder
Nathan Woo built products at Uber, Cruise (autonomous vehicles), and Monzo (Head of Engineering, US). Bioengineering, UC Berkeley. Built Halcy after a personal experience with a healthcare provider who was exceptional at his craft but invisible online. Halcy's entity-first approach comes from that same structured-systems thinking – applied to healthcare marketing.
