# Answer engine optimization (AEO)
Answer engine optimization (AEO) is the practice of structuring content so that ChatGPT, Claude, Perplexity, Google AI Overviews, and voice assistants pick it as the canonical answer.
Updated 2026-04-22
## [AEO in one paragraph](#aeo-in-one-paragraph)
AEO is about being the answer, not ranking for a keyword. Where SEO optimizes to _appear_ in a results list, AEO optimizes to _be quoted_ as the single sentence an answer engine generates.
## [AEO tools: what they actually do](#aeo-tools-what-they-actually-do)
An answer engine optimization tool typically bundles:
- **Prompt-based visibility testing.** Fire 50–500 prompts at ChatGPT, Claude, Perplexity, and Gemini; record citations.
- **Content gap analysis.** Identify questions where you have content but aren't cited.
- **Structured-data audit.** Check schema.org coverage (FAQPage, HowTo, Article, Organization) on key pages.
- **Quote-surface analysis.** Measure which paragraphs get pulled verbatim vs rephrased.
These tools are converging with GEO platforms. In practice, "AEO tool" and "GEO tool" buy the same feature set from different vendors.
## [Core AEO tactics](#core-aeo-tactics)
### [1. Answer in the first paragraph](#_1-answer-in-the-first-paragraph)
If the page is "what is X", the first paragraph must _define_ X clearly and quotably. Assume a scraper only reads 300 words before moving on.
### [2. Structure every answer as Q then A](#_2-structure-every-answer-as-q-then-a)
H2 = question, one paragraph = answer. Generative engines are trained on Q&A-shaped corpora (Stack Exchange, Reddit, FAQs) and reach for that shape naturally.
### [3. Ship the right schema.org](#_3-ship-the-right-schemaorg)
`FAQPage`, `Article`, `HowTo`, `Organization` are still the essentials. Validate with the [Schema markup validator](https://validator.schema.org/) and check our [llms.txt validator](https://mdream.dev/guides/answer-engine-optimization/tools/llms-txt/validator) while you're at it.
### [4. Open retrieval paths](#_4-open-retrieval-paths)
Publish an llms.txt, open AI crawlers you want citing you in robots.txt, and ensure your sitemap is clean. [Our AI audit](https://mdream.dev/guides/answer-engine-optimization/tools/ai-audit) covers all of this.
### [5. Avoid answer dilution](#_5-avoid-answer-dilution)
One page, one question. Don't bundle six FAQs under a single generic page unless each has its own schema and URL fragment. Engines rank fragments, not monoliths.
## [Measuring AEO](#measuring-aeo)
You need both:
- **Dashboard metrics:** citation share, prompt coverage, rank in answer box.
- **Log-based truth:** actual fetches from ChatGPT-User, PerplexityBot, ClaudeBot, Google-Extended.
Dashboards sample; logs don't. Weight logs higher.
## [Common pitfalls](#common-pitfalls)
- **Writing for keyword density instead of clarity.** AEO rewards concise, direct answers.
- **Shipping schema.org no one validates.** Broken JSON-LD is worse than none.
- **Blocking AI bots reflexively.** You're opting out of citations.
- **Treating AEO as a one-off.** Models update; your best answer from six months ago may now be outranked.
