A patient post-MI scrolling for "interventional cardiologist Cleveland" is not looking for a national SCAI member list. They want a local shortlist with named physicians, hospital systems, and procedure share at each cath lab. SCAI publishes the roster but does not ship city landing pages, so the search result page belongs to whoever does build them.

The data layer holds 600 US cities with cardiologist counts, fellowship-trained share, dominant hospital systems, and structural heart vs complex PCI mix. Each row maps to one URL via the slug column. cardiologist_count drives the hero stat, top_hospital a badge, and a JSON column of named physicians feeds a card grid through SleekRank list mappings.

The base page stays a normal WordPress page in your theme. Gutenberg, Bricks, Oxygen, or classic all work because SleekRank operates on rendered HTML. The XML sitemap auto-includes every /interventional-cardiologists/{slug}/, and stale rows 404 cleanly when a physician leaves the city or changes hospital affiliation in any season.

Cardiac care is regional. Patients select an interventional cardiologist based on distance to a cath lab capable of handling their case at 3am, not on a national member list. That is why "interventional cardiologist near me" and "interventional cardiologist [city]" together pull more monthly searches than national specialty queries.

A search form at the SCAI national site cannot win those queries against a competitor who shipped a real URL for each metro. Google ranks pages, not query parameters. The cities that rank carry specifics: cardiologist counts, dominant hospital systems, structural heart shares, named lead physicians, fellowship coverage.

Maintaining that uniqueness across 600 US metros by hand is unrealistic. Maintaining it across 600 rows in a sheet your outreach team already updates quarterly is a single afternoon of mapping work. SleekRank turns the operations sheet into the SEO surface, so the team that owns the cardiologist roster also owns the pages that rank for cardiology intent.
