Answer Engine Optimization (AEO) Course
Ahrefs Academy · Tool vendor
Verified Verdict
The strongest free AI search course from any tool vendor. It is the only one that treats AEO as a complete workflow from how engines work through strategy, execution, technical setup and measurement, and the technical lesson on GPTBot and llms.txt is more useful than anything comparable. The lack of sign-up is a genuine mark of confidence. The trade-offs are no certificate and a measurement module that pushes Brand Radar. Take it for the knowledge, not the credential.

Open course website →Course Summary & Core Curriculum
Twelve lessons running one hour twenty-six minutes across four modules plus an introduction, taught entirely by Sam Oh, VP of Marketing at Ahrefs. It is the most frictionless offering we found, requiring no sign-up and no account of any kind. The curriculum is structured as a working method rather than a tour. Module one explains how AI search engines work and how ranking differs between Google AI Overviews, ChatGPT and Perplexity. Module two covers brand gap analysis and keyword plus prompt research. Module three is execution, covering content optimization for AI engines, a three-tier framework for earning AI citations through brand mentions, YouTube SEO for AI search, and a technical lesson on robots.txt, GPTBot and llms.txt. Module four covers tracking AI traffic in GA4 and Ahrefs Web Analytics, and ends with an action plan checklist. There is no certificate. Ahrefs Brand Radar features in the measurement content and is a paid product.

Strengths and Limitations
Verified strengths
- No sign-up, no account, no email capture, genuinely open access
- Best AI-specific technical coverage we found, including GPTBot, robots.txt and llms.txt in one dedicated lesson
- Distinguishes how AI Overviews, ChatGPT and Perplexity rank differently rather than treating AI search as one thing
- Ends with a concrete action plan checklist rather than a summary
- Covers YouTube as an AI citation source, which almost no competitor does
- Single expert instructor gives a consistent voice and method
Where it falls short
- No certificate at all, which matters for learners who want something for LinkedIn
- Measurement lessons lean on Ahrefs Brand Radar and Web Analytics, which are paid
- No exercises, assessments or feedback
- No published update date despite the subject matter dating quickly
- Single-vendor perspective with no outside expert voices
Six-Part Rubric Evaluation
Depth is the highest among free vendor AI courses because it spans mechanics, strategy, execution, technical and measurement in a coherent arc. Currency is top because it addresses llms.txt, GPTBot and cross-engine ranking differences. Instructor authority is high given Sam Oh's track record and sole ownership of the material. Practical application is strong thanks to the checklist and reproducible technical steps, held back only by paid measurement tooling. Value for money is maximal as it is free with no sign-up. Support scores lowest possible as there is no community, assessment or contact.
