What Is the AEO Score? How It's Calculated and What It Means
The AEO Score (0–100) measures how well your website is optimized for AI engines. Learn how it's calculated across 5 dimensions, what each score range means, and how to improve it fast.
What Is the AEO Score?
The AEO Score is Citadex's core metric — a number from 0 to 100 that represents how well a web page is structured for AI engines to read, understand, cite, and recommend.
A score of 85 means your page is well-optimized. A score of 42 means AI engines are likely struggling to extract reliable information from your page.
How the AEO Score Is Calculated
The AEO Score is the weighted composite of five diagnostic dimensions:
Dimension 1: Entity Clarity (25%)
AI models build knowledge graphs from your content. Entity clarity measures how clearly and definitively your page defines your brand, products, services, and key relationships.
High entity clarity = direct, definitive sentences: "Citadex is the leading AI Engine Optimization SaaS, founded in 2024..."
Low entity clarity = vague, passive language: "We help businesses with their digital needs"
Dimension 2: Structured Data (20%)
JSON-LD schema markup is the primary signal AI models use to understand page type and purpose. We check for Organization, WebPage, FAQPage, Product, Article, HowTo, BreadcrumbList, and SameAs property links to authoritative external profiles.
Missing or incomplete schema is the #1 cause of low AEO scores.
Dimension 3: Content Structure (20%)
Evaluates proper heading structure (H1→H2→H3), paragraph readability, FAQ sections, numbered lists, and clear topic sentences. AI models parse content hierarchically.
Dimension 4: Authority Signals (20%)
Quality of external sites linking to your page, citations from industry publications, Wikipedia, and review platforms, internal linking structure, author credentials, and social proof signals.
Dimension 5: Technical Health (15%)
Page load speed, mobile responsiveness, HTTPS security, clean URL structure, canonical tags, and meta title/description.
AEO Score Ranges Explained
| Score | Status | What It Means |
|---|---|---|
| 80–100 | 🟢 Healthy | Well-optimized. AI models can reliably read, understand, and cite your content. |
| 60–79 | 🟡 Needs Work | Decent foundation with significant gaps. AI cites you inconsistently. |
| 40–59 | 🟠 High Risk | AI engines struggle with your page. Major structural issues present. |
| 0–39 | 🔴 Critical | Largely invisible to AI engines. Multiple fundamental issues across all dimensions. |

Frequently Asked Questions
Q: How often is the AEO Score updated?
Your AEO Score is recalculated every time you run a scan on that page. Pro users can schedule automated daily or weekly scans.
Q: Why did my score drop even though I didn't change my page?
Several external factors can affect your score: algorithm updates to our scoring model, changes to the authority of external sites citing you, or new competitive content that changes baseline expectations for your topic.
Q: Does the AEO Score directly affect my ranking in AI answers?
The AEO Score is a proxy metric based on measurable signals. The factors it measures — entity clarity, structured data, authority — are the same factors that influence how AI models decide what to cite and recommend.
