Signal & Reach

Marketing has become fragmented. Businesses are told to focus on SEO, social media, email, paid advertising, content, AI, and dozens of other tactics-yet few understand how these pieces work together.

Signal & Reach presents a practical marketing operating system designed for the AI era.

Girish Kotte breaks modern marketing into five connected layers: Foundation, Authority, Discovery, Audience, and Conversion. Instead of treating marketing channels as isolated tactics, this book shows how each layer strengthens the next-and how to identify the weakest part of your system before wasting more time or money.

Inside, you'll learn how to:

• Build a strong marketing foundation and positioning strategy
• Develop authority through links, reviews, citations, and independent evidence
• Improve visibility across traditional search and AI-powered discovery
• Understand SEO, AIO, AEO, and GEO in the modern search environment
• Build an audience through social media, email, communities, and outreach
• Turn traffic into customers through better landing pages and conversion systems
• Create offers and copy that communicate value clearly
• Build a more disciplined approach to paid advertising
• Increase retention, referrals, and customer lifetime value
• Understand CAC, budgets, hiring, and marketing economics
• Use AI to build and operate a modern marketing department

The book introduces the Signal Stack and Signal Loop, giving founders and marketing teams a repeatable framework for deciding what to work on next, measuring performance, and allocating the next 90 days of marketing effort.

Whether you're a founder, marketer, consultant, agency owner, or business leader, Signal & Reach is designed to help you stop chasing disconnected tactics and start building a marketing system that compounds.

Marketing doesn't need more noise. It needs a system.
