What the project
needed to do.
Air Solutions Heating & Cooling commissioned a build replacing a 36-page WordPress brochure with a programmatic SEO platform: 249 indexed pages at launch, a 9-type Schema.org architecture, four custom interactive tools, and a native automated publishing engine. The same architectural pattern Netflix and Vercel use for production applications, applied to a local HVAC contractor in Baldwin County, Alabama.
The previous airsolutionspros.com site was a 36-page WordPress brochure being maintained, not built to compete. Despite Air Solutions holding the strongest review velocity in Baldwin County, the business showed 0% Share of Local Voice in south Baldwin markets — Foley, Gulf Shores, Orange Beach — where its trucks operate daily. Distance to the home address is fixed; relevance is improvable. The platform's job was to close the relevance gap with 135 dedicated city × service pages, then sustain that advantage with a content engine that publishes without manual intervention.

How the build
earns the call.
Built around the programmatic-SEO methodology used at the enterprise level by Airbnb, Zapier, Tripadvisor, and Zillow — applied to a single county. Every city × service combination is a standalone indexed page with unique local content, proper metadata, schema markup, and internal links. The 9-type Schema.org architecture includes the HVACBusiness subtype, OfferCatalog with all 9 services listed, and per-city postalCode arrays across all 15 Baldwin County cities — enterprise-level structured data implementation at a local-contractor scale.
Gives Air Solutions the strongest technical local-search platform in Baldwin County HVAC. Edge markets where no competitor has a single dedicated page now have nine service pages each. The content engine compounds: every post that indexes adds an authority signal Google reads as active business, on a publishing cadence competitors cannot match.
Programmatic SEO is the same architectural pattern Airbnb uses for apartments per city, Zapier for app integrations, and Tripadvisor for restaurants per neighborhood. Applied to a single Baldwin County HVAC contractor, it produces 135 city × service intersection pages, an automated content engine, and a category of digital asset no competitor in the market currently occupies.Studio rationale
