TDC Signal Documentation
TDC Signal tracks how AI engines mention your brand when buyers ask for advice. It shows why you win or lose each answer and drafts the content that helps you win more.
What TDC Signal Does#
Buyers now ask AI assistants which product to buy, which agency to hire or which tool to use. TDC Signal asks the same questions for you, on a schedule, and records every answer. It covers six AI engines:
- ChatGPT
- Perplexity
- Microsoft Copilot
- Gemini
- Google AI Mode
- Google AI Overviews
See, Understand, Fix#
TDC Signal works as a loop with three stages:
- See: checks collect answers to your questions. Overview, Answers and Competitors show how often each engine names you, in what position and in what tone.
- Understand: Opportunities shows the questions you lose, the searches the engines ran and the pages they cited instead. Page Audit scores your pages for AI readiness.
- Fix: Fixes drafts new pages, FAQ sections, structured data and more. You review and publish each draft yourself. Impact then shows your visibility before and after the change.
