What are the 48 AEO criteria?

The 48 criteria are organized into 5 pillars with fixed target shares: Answer Readiness 40%, Content Structure 25%, Trust & Authority 15%, Technical Foundation 10%, and AI Discovery 10%. Inside those pillars, criteria cover topic coherence, original data, depth, fact density, direct answers, Q&A structure, entity authority, freshness, visible dates, schema, semantic HTML, extraction friction, llms.txt, robots.txt, licensing, canonicals, sitemap coverage, and RSS. Each criterion is scored 0–10, converted into an effective weight after confidence and overlap controls, then rolled into the final score.

Can I request a re-audit of my website?

Yes. After making improvements based on audit recommendations, request a fresh audit to see your updated score. Each re-audit creates a new version you can compare against previous ones to quantify progress.

How long does it take for AEO changes to affect AI visibility?

Technical changes — Schema.org, robots.txt — get picked up by AI crawlers within days to weeks. Content changes — FAQ pages, Q&A restructuring — take weeks to months to be fully indexed and reflected in AI answers. Unlike SEO, there's no established timeline. AI systems re-index on their own schedules.

How often are benchmarks updated?

Automatically, whenever new audits are published. Each audit includes a timestamp so you know how current the data is. Industries with more audited domains have more reliable benchmarks. We're continuously expanding coverage across sectors.

Should I update old content or create new content?

Both — but updating existing high-performing content often yields faster results. Add Q&A headings, FAQ schema, author attribution, and internal links to existing pages. For new content, focus on topics where you have genuine expertise or original data. AI engines value freshness, so update publication dates when you substantially revise content.

Scoring Methodology

How Your AEO Site Rank Is Calculated

A weighted average of 48 deterministic criteria. Each scored 0-10, each with a specific weight. No AI judgment calls - every point is traceable.

Moderate visibilityOut of 100 possible points

The Formula

Score = sum(criterion_score / 10 * weight * 100) / sum(weights)

Each criterion is scored 0-10 by deterministic checks, multiplied by its weight, and summed to produce a 0-100 overall score.

Speakable Schema Markup

Voice assistants need to pick which paragraph to read aloud from your page. Without Speakable markup, they guess -and they frequently guess wrong, reading your cookie notice.

Image Context for AI: Your Pictures Are Worth Zero Words Without Markup

AI can't see your images. It reads the markup around them. A product photo with alt="image1.jpg" tells AI nothing. A figure with a descriptive figcaption and 8-word alt text tells AI exactly what it's looking at - and that context feeds directly into citation decisions.
