When building vertical web applications, separating feature comparisons into standalone, fast-loading micro-sites is an effective way to keep your core application bundle lean while addressing specific user intents.

Recently, while building out supporting comparison pages for an educational test simulator, I designed a reusable data schema in TypeScript to render head-to-head feature matrices and inject structured JSON-LD data automatically.

Here is the architectural pattern and data model used to build these static comparison micro-sites.

1. Defining the Comparison Data Model in TypeScript

Instead of hardcoding HTML tables for each competitor analysis, defining a strict TypeScript interface ensures every micro-site renders consistent evaluation metrics (pricing model, learning format, regulatory updates, and pass guarantees):

export interface ComparisonMetric { featureName: string; primaryPlatformValue: string | boolean; competitorValue: string | boolean; highlightAdvantage?: boolean; } export interface ComparisonSiteConfig { slug: string; title: string; competitorCategory: 'legacy-portal' | 'career-directory' | 'trade-school'; lastUpdatedYear: number; metrics: ComparisonMetric[]; }

By typing the competitorCategory, the UI components can dynamically adjust the layout depending on whether we are comparing two software tools or comparing digital self-study against an offline curriculum.

2. Live Production Deployments (Built on Lovable)

Using this modular structure, I deployed three separate micro-sites targeting different segments of the HVAC certification space:

3. Automating FAQ & Comparison JSON-LD Schema

To help search engines and AI answer engines parse the comparison matrices accurately, each micro-site injects a structured FAQPage and WebPage JSON-LD payload into the document head:

TypeScript

export function ComparisonSchema({ title, url, description }: { title: string; url: string; description: string }) { const schemaData = { "@context": "https://schema.org", "@type": "WebPage", "name": title, "url": url, "description": description, "specialty": "EPA Section 608 Certification Prep" }; return ( <script type="application/ld+json" dangerouslySetInnerHTML={{ __html: JSON.stringify(schemaData) }} /> ); }

Key Takeaways for Frontend Builders

  1. Decouple Content from Layout: A shared TypeScript schema lets you spin up multiple comparison landing pages in minutes.
  2. Keep Micro-Sites Focused: Rather than building one massive table comparing ten different business models, isolating each comparison into its own deployment keeps page speed high and user intent clear.
