Architecture

SEO/AEO Foundation

JobFlow is built from day one to rank in both Google and AI engines (ChatGPT, Perplexity, Google AI Overviews).

• /llms.txt — Brand summary for AI assistants
• /agent.json — Structured metadata for autonomous agents
• Programmatic SEO pages — 50+ initial pages targeting best {category} for {trade} queries
• Schema markup — SoftwareApplication, FAQPage, HowTo, BreadcrumbList on every page
• Citation-ready content — Summary-first structure, original data, named entities

Vertical SaaS Model

• Single trade focus: HVAC only (Phase 1), expand later
• Workflow-locked retention: Mission-critical daily operations
• Embedded payments: Stripe Connect lets homeowners pay HVAC techs through the app (0.5-1% transaction fee)
• Industry moats: Compliance, HVAC-specific data, trade community network effects
