Learn AI

A free, plain-English course in using AI well - and in being found by it.

A free course in using AI properly, written in plain English for people who work in marketing. Start from zero if you are new. Then go deep on AI search: how ChatGPT, Perplexity and Google AI Overviews decide which sources to quote, and how to make sure yours is one of them. No sign-up, no email required.

About this course

How it is written, and what it costs

Why this exists

Most AI advice is either too shallow to act on or too technical to follow. This is an attempt at neither: one page per question, written in plain English, complete enough that you do not have to go looking elsewhere afterwards.

I have spent twelve years in search. The part that interests me now is what happens when the search box is replaced by an answer and nobody clicks through. Most of this course is about that shift, and about what a marketer can actually do about it.

How the pages work

Every page follows the same shape, so once you have read one you know how to read all of them:

  1. The answer, in the first sixty words. If that is all you needed, you can leave.
  2. Key points, so you can decide whether the rest is worth your time.
  3. The explanation, with a diagram where a diagram helps.
  4. Do it yourself, as numbered steps you can follow today.
  5. Common mistakes, and the part nobody else writes: when the advice does not apply.
  6. Questions, including the awkward ones.

Every page carries the date it was last checked. If something has changed since, the page is wrong until I fix it, and the date tells you how likely that is.

What it costs

Nothing. There is no sign-up, no email capture and no course to buy at the end. If you would rather have someone do this work than learn it, that is what my consulting is for. It gets one mention, at the bottom, rather than four per page.

Want this done rather than learned?

I run AI visibility audits and consult on AI search for brands and agencies. One conversation, no deck.
