SEO architecture decided before visual design.
The page hierarchy, the URL structure, the internal-link plan, the schema layer, and the canonical strategy all sit upstream of the visual brief. Practices that build the site visually first and retrofit SEO architecture afterward end up with information architecture that fights the commercial-query intent. A specialty group with cardiology and electrophysiology sub-practices needs the EP sub-practice on its own page tree from day one, not bolted onto the cardiology page when ranking gaps surface a year in.
