AI Credibility
Factual explicitness (Evidence & Trust, Index E) contributes 40% of the AIA Score and uses AI-model estimates of concrete details, ambiguity, and unanswered questions.
How it is scored today
Index E is calculated only from three AI-model estimates, each between 0 and 100:
- Fact density: how much content contains concrete details such as names, dates, prices, locations, and quantities.
- Ambiguity: how much language is vague or subjective.
- Unanswered questions: whether practical questions about the service, cost, or location remain unanswered.
Each input is an AI-model estimate. The calculation does not count entities or divide their count by the total word count.
E = clamp((fact density − ambiguity − unanswered questions) / 2, 0, 100)
Clamp limits the result to the range 0–100. With the current formula, E can reach at most 50, even though each estimate uses a 0–100 scale.
Estimates can vary between runs. A concrete claim is not necessarily true: the score does not verify facts.
Structured data (JSON-LD or schema), authorship, sources, and evidence are not checked and do not affect the score. The position of an answer on the page is also not checked.
See AIA Score Explained for the full calculation.
How to improve these inputs
- Include accurate, concrete details about your services, prices, locations, dates, and quantities.
- Replace vague claims with specific statements. For example, use “Orders usually ship within two business days” when that accurately describes your service.
- Answer common customer questions, including what you offer, what it costs, where it is available, and how to get started.
These changes address the inputs used by the model, but they do not guarantee a particular score increase.
Recommended practices (not currently scored)
The following practices can help readers understand and assess your content, but they are not measured by the current score:
- Publish accurate JSON-LD that matches the visible content.
- Identify named authors where appropriate.
- Cite sources that support factual claims.
- Place practical answers early on the page so readers can find them easily.
