The Certified Answer Engine Optimization Professional (CAEO) is a beginner, vendor-neutral certification for the people optimizing content to win direct answers. It validates that you understand AEO foundations and where it fits, know the answer engines and SERP features you optimize for, can write content that earns answers, can implement structured data and schema, can optimize for voice and conversational search, and can measure and improve results. The exam is computer adaptive and performance-based, and the credential is kept current through continuing education.
| Level | Beginner. An entry credential: it establishes solid AEO fundamentals and assumes some content or SEO exposure but no advanced background. |
|---|---|
| Delivery model | Computer adaptive, three stages. Your score on each stage selects the difficulty of the next, so no two candidates sit the same paper. |
| Format | 60 questions. A performance-based exam that includes performance-based questions and multiple-choice questions. Concepts transfer across every content and search platform. |
| Time | 90 minutes for the whole exam, timed. Autosaves every answer. |
| Scoring | You need a score of 700 out of 900 to pass. Results are reported on a scale of 100 to 900, and 700 corresponds to answering 72% of the exam correctly. Harder questions carry more weight, so a score means the same thing on any route. Multiple-response items and PBQs are all or nothing. |
| Retakes | No waiting period after a failed first attempt. Every attempt is paid for at the exam price. See the CertLabz Certification Retake Policy. |
| Voucher validity | 12 months from purchase, for one sitting. |
| Certification validity | 3 years. Renew with 35 CEUs per cycle and the $25 annual CE fee, or pass the current exam. Renewal details. |
| Language | English. |

A signed, verifiable:
The CAEO is a performance-based exam: it includes performance-based questions alongside multiple-choice questions. Instead of only picking A, B, C or D, you match features to their use, order an optimization task, fix a content or schema problem, and choose the right approach. It is computer adaptive, is proctored and timed, needs no mandatory course, and tests optimizing for answers rather than reciting one tool's menus.
What AEO is, answers versus links, search intent, and the SERP features you optimize for.
Answer-first writing, question headings, structured data and rich results.
Voice assistants, natural language queries, speakable content and local answers.
Tracking snippets, monitoring positions, testing, iterating and reporting.
Answer engines are changing how people search, and practitioners who can optimize content to win direct answers are increasingly in demand across marketing and content teams. Every route is shown here at once, so nothing is hidden behind a control you have to find.

Every form is drawn from a bank of more than 90 items to these exact weights, whichever adaptive route you take. Filter by the area you want to study.
The exam runs in three stages. Your score on each stage selects the difficulty of the next, so a strong candidate is stretched and a struggling one is measured fairly rather than swamped. No two candidates sit the same paper. Harder questions carry more weight, so a scaled score means the same thing whichever route you took.
Each exam can have up to 5 to 12 performance-based questions, drawn fresh on every attempt, alongside the multiple-choice questions. A PBQ is a task rather than a list: you match features to their use, order an optimization task, fix a content or schema problem, or choose the right approach. They are scored all or nothing, so partial guesses do not pass.
The CAEO is vendor neutral and describes content and search tools generically, naming products only as examples. It tests the AEO judgement that transfers across platforms.
Yes. Where a capability such as a schema type or a snippet feature is involved, it is described by what it does, not tied to one product.
700 out of 900. Results are reported on a scale of 100 to 900, and 700 corresponds to answering 72% of the exam correctly.
There is no waiting period between a failed first attempt and a second attempt. Buy another voucher and sit the exam again when you are ready, and it will draw a fresh adaptive form from the bank. See the CertLabz Certification Retake Policy.
Yes, after three years. Keep it current by logging 35 CEUs during the cycle and paying the $25 annual CE fee before expiry, or by passing the current exam again.

CAEO is a continuing-education certification, like the CE credentials from CompTIA and ISC2. It is valid for three years from the day you pass. To keep it, log 35 continuing-education units during the cycle and pay the $25 annual CE fee before your expiry date. Or pass the current version of the exam again. Earning a higher-level CertLabz certification renews it too, the way CompTIA certifications stack.
CEUs are logged from your CertLabz dashboard with supporting evidence. A certification that lapses can be reinstated only by passing the current exam.
