GEO and AEO: how to make content citable by answer engines

Executive brief

Key takeaways

• Answer the main question in the first few lines.
• Connect important claims to verifiable evidence.
• Use semantic HTML and JSON-LD as reinforcement, not as a substitute for content.
• Keep entities, authorship and update information consistent.

GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) are practices that make a page easier to interpret, summarize and cite. They work best when built on solid technical SEO, original content and a good reading experience.

The central question is not “how do we write for AI?” but “how do we publish a clear, verifiable answer that is easy to attribute?”

Start with a self-contained answer

The introduction should explain what the concept means and when it matters. Do not open with a long market history before delivering the answer. For definitional questions, a passage of 40 to 70 words is often complete enough for the reader and clearly delimited for extraction.

A strong opening answer:

• names the concept without ambiguity;
• addresses the primary intent;
• includes the most important condition or limitation;
• prepares the reader for the sections that follow.

Structure content as a decision tree

Use one h1 for the main topic. Each h2 should answer a real subquestion, while h3 headings explain methods, criteria or examples. This hierarchy creates a tree that people, screen readers, search engines and retrieval systems can navigate.

Prefer headings that carry meaning

“How to measure readiness for AI answers” is more useful than “Measurement.” Descriptive headings act as small summaries and improve navigation through a table of contents, keyboard or automated tool.

Keep evidence close to the claim

When using a number, method or conclusion, identify the source, period and limitation. Citable content distinguishes observation, inference and recommendation. This discipline reduces promotional claims that cannot be checked.

Use structured data to confirm visible content

Article schema identifies title, author, publication date, update date and publisher. BreadcrumbList records page hierarchy. FAQPage describes questions and answers that must also be visible to visitors.

Structured data must not introduce claims that are absent from the interface. Treat JSON-LD as a semantic confirmation layer.

Create extractable blocks without breaking the reading experience

TL;DR sections, key takeaways, criteria lists, comparison tables and FAQs support readers with different levels of time and familiarity. They also delimit answers that may become snippets, summaries or citations.

Avoid repeating the same information many times. The summary states the conclusion; the body demonstrates and contextualizes it; the FAQ addresses specific objections.

Measure what can be verified

There is no universal “GEO score.” Track observable indicators: question coverage, indexation, impressions, references, traffic from answer engines, assisted conversions and entity consistency.

The final objective remains commercial: be understood by the right people and make their next decision easier.

Frequently asked questions

What is the difference between SEO, GEO and AEO?

SEO improves discovery and ranking; AEO makes direct answers easier; GEO improves content clarity and citability in generative engines. In practice, all three share a technical and editorial foundation.

Does FAQ schema guarantee a Google feature or an AI citation?

No. Markup helps machines interpret content, but it does not guarantee a rich result, ranking or citation. The visible answer still needs to be complete and useful.

Is llms.txt required for GEO?

No. It is an emerging proposal and is not a Google Search requirement. It may serve as a supplementary index for systems that support it, but it does not replace crawlability, useful content or structured data.
