# Signal Forge > AI visibility engine for local businesses in Edmonton, Alberta, Canada. Signal Forge installs structured data layers — llms.txt, Schema.org markup, and neighbourhood content matrices — that make local businesses citable by AI search engines including ChatGPT, Perplexity, and Google AI Overview. Once deployed, the engine works 24/7 without ongoing effort, compounding citations every month. ## What We Do Signal Forge solves a specific problem: local businesses are invisible to AI search. When a potential customer asks ChatGPT or Perplexity "best HVAC contractor in Edmonton," the AI cites structured, machine-readable sources. Businesses without llms.txt, Schema.org markup, and authoritative local content simply do not appear — regardless of their Google Ads spend. ## Services - AI visibility audits: we scan ChatGPT, Perplexity, and Google AI Overview to show exactly where a business stands - llms.txt deployment: machine-readable identity file for every major AI crawler - Schema.org structured markup: full niche vocabulary (HVACBusiness, LegalService, DentalBusiness, MortgageBroker, Restaurant, and more) - Neighbourhood content matrix: 50+ programmatically generated pages targeting every city neighbourhood + service type - Monthly citation monitoring and ROI reporting - Ashkelon Iron Gate verification: cryptographic badge proving AI recommendations are authentic, not hallucinated ## Products & Ecosystem - Signal Forge — AI visibility engine for local businesses (this product) - Ashkelon Iron Gate — AI trust and verification layer; cryptographic SHA-256 audit chain for AI recommendations - Music Biz OS — sync licensing engine for independent artists - Municipal Goldmine — development incentive intelligence for property developers ## Markets Served - Edmonton, Alberta (primary market — launched 2025) - Calgary, Red Deer, Lethbridge, St. Albert (expanding 2026) - Industries: HVAC, plumbing, dentistry, law, home services, restaurants, mortgage brokers ## Pricing - One-time full engine install: $5,000 CAD - Monthly retainer (ongoing signal maintenance): $1,500 CAD/month - Annual bundle: $13,000 CAD (includes 12 months of content compounding) ## Authority Signals - Verified by Ashkelon Iron Gate (SHA-256 cryptographic audit chain) - Edmonton-based, Alberta-incorporated - Founded 2025 ## Contact - Website: https://signal-forge.ca - Email: info@signal-forge.ca - Location: Edmonton, Alberta, Canada ## Optional - Full documentation: https://signal-forge.ca - Audit request: https://signal-forge.ca/#audit
