What is AEO and how is it different from SEO
AEO stands for answer engine optimization. The optimization target is not a ranked list of blue links. It is a generative answer that an AI model composes, often with a small set of cited sources. The page that gets cited is the page that the model can extract a clean, attributable answer from in one or two passes.
| Discipline | Optimization target | Primary signal |
|---|---|---|
| SEO | Top 10 ranked results | Backlinks plus content quality |
| AEO | Citation in a generative answer | Extractable structure plus entity clarity |
| GEO | Inclusion in generative summaries | Topical authority plus freshness |
The 14 point AEO checklist
- Lead with the answer. Your first 60 words contain the direct answer to the implied question in the headline.
- Headline is a question or a clear claim.AI engines map question intent to question style headlines.
- H2 sections phrased as questions.What, why, how, when. Each H2 ends in a question mark or names a specific claim.
- FAQ schema markup. Use FAQPage JSON LD for at least three question and answer pairs per page.
- Definitions early. Define every domain term in the first paragraph that uses it.
- Short answer paragraphs. Two to four sentences. Models lift them whole.
- Comparison tables. Tables get cited for any X vs Y query.
- Numbered lists for procedures. When the topic is a how to, use ordered lists. AI engines extract them as steps.
- Named entities. Use precise product, person, and place names with consistent spelling.
- Author byline. Article schema with author and date. AI engines weight authored content over anonymous content.
- Citations to primary sources. Link to official docs, original studies, or authoritative datasets. Do not block them with cookie walls.
- Freshness signal. Updated dates on posts that are revised. AI engines bias toward recent.
- No anti scraping walls. Allow GPTBot, ClaudeBot, and PerplexityBot in your robots.txt unless you have a strong reason to block them.
- Mobile readable. Render correctly without JS. Many AI fetchers do not run JS at fetch time.
How to test if your page is AEO ready
Go to ChatGPT, Claude, and Perplexity. Ask the question your page is meant to answer. If your page is cited, your AEO is working. If a competitor with a weaker domain authority is cited and you are not, your structure is the gap, not your authority.

Common AEO mistakes
- Burying the answer five paragraphs deep behind brand storytelling.
- Mixing answers with sales pitches that confuse the model on intent.
- Skipping FAQ schema. It is the cheapest AEO win.
- Long tables of contents that look like product navigation.
- Author missing from schema. AI engines downweight anonymous content.
Frequently asked
Quick answers
- What is the difference between AEO and SEO?
- SEO targets ranked search results. AEO targets generative answers in AI engines like ChatGPT and Perplexity. The structure of the page matters more for AEO than for SEO. Backlinks still matter for both, but for AEO, extractable structure and entity clarity are the primary levers.
- Do I need to block GPTBot?
- No. Block it only if you sell access to your content. For a marketing site, you want GPTBot, ClaudeBot, and PerplexityBot to crawl freely so your pages can be cited.
- How do I add FAQ schema?
- Add JSON LD FAQPage markup to the page head. Each Question entity has a name and an Answer entity with text. Validate at schema.org or in Google Search Console.
- How long should an AEO post be?
- Long enough to fully answer the question. 800 to 1500 words is typical. Padding hurts. AI engines extract from concise sections, not from word count.
- Does AEO replace SEO?
- No. AEO sits next to SEO. The same content can rank in Google and be cited in ChatGPT if it is structured well. Treat AEO as a layer of polish on top of solid SEO.
