We rebuilt Watson Heating + Cooling from a one-page Squarespace site into a high-performance Next.js platform
A 39-page rebuild focused on speed, SEO readiness, accessibility, and long-term ownership.
Watson Heating + Cooling came to us with a one-page Squarespace site, where eight services, a nine-slide review carousel, the service plan, the gallery, and the contact form all shared a single URL. We migrated the site to a custom Next.js build, delivered near-perfect Lighthouse scores, and gave the business a dedicated page for every service and every service area.

Challenges & Solutions
What stood in the way, and how we cleared it.
The whole site lived on one page
Eight services, a nine-slide review carousel, the service plan, the gallery, and the contact form were all sections of a single URL. Every visit landed on the same document no matter what the visitor came for, and there was no page-level structure to optimize.
We rebuilt the site in Next.js with route-based code splitting, image optimization, and a leaner front-end architecture designed for fast rendering.
The old site had weak SEO foundations
The single page carried one title and an empty meta description for the whole business, so search engines had almost no clear relevance signals to read. There was no page for furnace repair, and no page for Fort Thomas, that could rank on its own.
We restructured the information architecture, implemented semantic page layouts, improved metadata control, and created a crawl-friendly Next.js build with server-rendered content.
The homepage lacked clarity and conversion direction
The original site analysis indicated that the homepage did not clearly explain what the business did, lacked trust signals, and offered no strong calls to action.
We redesigned the homepage around a clearer value proposition, service summaries, trust-building sections, and stronger CTA placement to guide users toward contact and service actions.
The Transformation
The site Watson Heating + Cooling had, and the one they have now.
Our Strategy
A phased approach to delivering measurable results.
Platform audit and migration planning
We started by cataloguing everything the existing one-page Squarespace site carried, documenting structural gaps, and mapping the full migration path into a custom Next.js application.
- Content inventory of the existing one-page site
- Page inventory for 39 URLs
- Migration roadmap
- Technical architecture plan
Content and UX restructuring
We reorganized the site around clearer messaging, stronger service hierarchy, and conversion-focused page flows so visitors could immediately understand the business and take action.
- Homepage content structure
- Service page framework
- CTA placement strategy
- Trust signal and section planning
Custom Next.js development
We rebuilt the website in Next.js using a component-based system that improved performance, maintainability, and scalability compared to the previous one-page setup.
- Next.js application build
- Reusable React components
- Responsive front-end implementation
- Optimized routing and rendering setup
Technical SEO and accessibility implementation
We layered in semantic structure, metadata controls, accessibility improvements, and best-practice front-end implementation to strengthen search readiness and usability.
- Metadata implementation
- Semantic heading structure
- Accessibility refinements
- Technical SEO QA
Launch, QA, and performance validation
Before launch, we tested the site across key pages and validated the final build against Lighthouse benchmarks to ensure the migration delivered measurable quality improvements.
- Cross-page QA
- Launch checklist
- Lighthouse validation
- Post-launch handoff
Results
Measurable outcomes that speak for themselves.
