Icarus Works
The AI Search Knowledge Hub

Learn AI search — properly.

The ground under "being found" has shifted. ChatGPT, Perplexity, Gemini, and Google AI Overviews now answer buyers directly — naming a handful of brands instead of listing ten links. This is a genuine, extensive education in how that works and how to earn your place in the answer: 30 guides across 6 categories, from first principles to trade-by-trade playbooks. Plain words, honest mechanisms, no hype.

New to all of this? Follow the beginner learning path below — six guides, in order, that take you from "how does AI search even work" to "how do I get cited." Run a local trade business? Jump straight to your trade playbook. Want a term defined? The glossary has 46.

How to use this hub

A real education, organized so you can actually navigate it.

This isn't a link dump. It's structured into six categories — from fundamentals to hands-on trade playbooks — with a guided path for beginners and pillar guides that go deep. Read in order or jump to what you need; every guide is written answer-first, so you can skim or study.

Three ways in, depending on where you are:

  • Brand new? Take the beginner learning path — six guides in reading order, roughly an hour total, that build from mechanics to action.
  • Run a local trade? Go straight to a trade playbook — a complete, practical field guide for roofing, HVAC, solar, pest control, electrical, or window replacement.
  • Looking something up? Use the category browser or the glossary. Everything is cross-linked.

FAQ
Where should I start if AI search is completely new to me?

Start with the beginner learning path on this page — it walks you through six guides in order, from how AI search works to how to get cited and how schema helps. Then branch into the category that fits your goal.

Is this information free?

Yes. Every guide, playbook, and glossary entry here is free to read. If you want to see where AI names you today, you can run a free visibility scan — but nothing here is gated.

How current is this?

AI search is moving fast, so we describe mechanisms as observable behaviour and hedge where the field is still shifting. Where specifics change (like incentive rules or engine features), we say so rather than state stale facts as permanent.
