The AEO Canon at a Glance
A one-page reference to the AEO Canon — the eight pillars of Answer Engine Optimization in three layers, each with its core principle and the evidence behind it.
This is the AEO Canon on one page: eight pillars of Answer Engine Optimization, in three layers, each a single condition for earning a citation from AI. Use it as a quick reference — a summary card to scan, share, or return to — and follow any pillar through to its deep-dive when you need the detail. For the full treatment, see the complete AEO Canon.
The three layers
The Canon stacks into three layers, read top to bottom. Each answers one question and assumes the layer above it is solved. Foundation is about being usable by a machine; Reputation is about being trusted once you're usable; Momentum is about staying chosen once you're trusted. The order is the point — you can't earn a reputation on content an engine can't read, and you can't sustain momentum on a reputation you never built.
| Layer | Pillars | The question | The work |
|---|---|---|---|
| Foundation | Access · Alignment · Extractability | Can the machine use you? | Technical + editorial |
| Reputation | Authority · Credibility · Originality | Does the web vouch for you? | Earned + evidenced |
| Momentum | Freshness · Adaptability | Do you stay chosen? | Operational |

The eight pillars
Each pillar reduces to one principle and one piece of evidence — and each is a single, necessary condition for being cited. Read the principle column as the one sentence to remember per pillar; read the evidence column as the reason it earns a place in the framework rather than someone's opinion. This is the whole Canon in a table.
| # | Pillar | Principle | Evidence |
|---|---|---|---|
| 1 | Access | If a machine can't read you, it can't quote you. | 0 JS executed by GPTBot (Vercel, 500M requests) |
| 2 | Alignment | Answer the question people actually ask AI. | Search was keywords; AI is conversation |
| 3 | Extractability | Cite-worthy passages, not pages — answer first. | 44% of citations from the first third (Profound) |
| 4 | Authority | AI trusts what the web trusts; mentions over links. | 0.664 vs 0.218 correlation (Ahrefs, 75k brands) |
| 5 | Credibility | Back every claim; show your work. | ~40% visibility lift from evidence (Princeton GEO) |
| 6 | Originality | Be the primary source, not an echo. | Generic content is infinite; originality is scarce |
| 7 | Freshness | The recent wins; undated reads as expired. | 65% of crawler visits to content <1yr (Seer) |
| 8 | Adaptability | The engines change monthly; your doctrine must too. | ~11% citation overlap between engines |
Why a cascade, not a checklist?
The pillars are sequential because an engine processes you in order: it has to be able to read you before it can choose you, and choose you before it can keep choosing you. So a break high in the stack neutralizes every strength beneath it. A credible, original, freshly-updated page behind a blocked crawler earns nothing, because Access — the first gate — failed. This is the single most important thing to internalize: don't spread effort evenly across eight pillars; find your highest broken gate and fix that one first.
The headline numbers
If you remember nothing else, remember these four figures — each is the evidence anchoring a pillar, and together they show the Canon is built on measured findings rather than opinion.
Sources for the figures above: the Princeton GEO study (arXiv 2311.09735), Ahrefs' analysis of 75,000 brands, Seer Interactive's content-recency study, and Vercel's AI-crawler report.
How to use it in 30 seconds
Walk the pillars in order and stop at the first one you fail — that is where to work. Fixing a lower pillar while a higher one is broken changes nothing, because the engine never gets far enough to reward it. The Canon is a cascade, not a checklist: your visibility is capped by your highest broken gate, so the highest "no" below is your single highest-leverage fix. Resolve it, then re-run.
- 1
Can crawlers read your raw HTML?
No → fix Access first.
- 2
Are you answering the real question?
No → fix Alignment.
- 3
Is your answer in the first sentence?
No → fix Extractability.
- 4
Does the web mention you?
No → build Authority.
- 5
Do you show evidence inline?
No → add Credibility.
- 6
Are you a primary source?
No → invest in Originality.
- 7
Is your content current and dated?
No → restore Freshness.
- 8
Do you measure per engine?
No → build Adaptability.
Want this run for you? The interactive Canon diagnostic steps through each gate and points you to the deep-dive for the first pillar you break. New to the framework entirely? Start with what is AEO and then the full AEO Canon. And once you've found your first broken gate, the conviction behind the whole method is laid out in the AEO Manifesto — the case for why deserving the citation is the only strategy that lasts.
Frequently asked questions
- What are the eight pillars of the AEO Canon in order?
- Access, Alignment, Extractability (the Foundation layer), then Authority, Credibility, Originality (the Reputation layer), then Freshness and Adaptability (the Momentum layer). They are sequential — fix the highest broken pillar first.
- What are the three layers of the AEO Canon?
- Foundation (can the machine use you?), Reputation (does the web vouch for you?), and Momentum (do you stay chosen as things move?). Each layer assumes the one above it is already in place.
- What's the fastest way to apply the Canon?
- Walk the eight pillars top to bottom and stop at the first one you fail — that is your highest-leverage fix. The interactive Canon diagnostic does this for you and links you to the pillar you break.
