What is AEO (AI Engine Optimization)?

AEO is the practice of structuring your website so AI answer engines - ChatGPT, Perplexity, Google AI Overviews, Claude - can find, understand, and cite it. SEO gets you ranked in search results. AEO gets you into AI-generated answers. Different game, different rules.

What does the free AEO audit include?

The free audit analyzes your website across 48 criteria that determine AI visibility, including llms.txt, Schema.org structured data, Q&A content format, clean crawlable HTML, entity authority, robots.txt AI policy, FAQ sections, original data, content freshness, fact density, canonical URLs, and more. You get a score out of 100 with specific findings and actionable recommendations.

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.

What happens if my site scores below 20?

A score below 20 means most fundamental AEO infrastructure is missing - no llms.txt, no relevant schema, likely blocking AI crawlers, no FAQ content. The good news is the fastest gains come from this starting point. Adding llms.txt, basic Organization schema, and unblocking AI crawlers in robots.txt can double your score in a single day.

What is llms.txt and do I need one?

llms.txt is a plain-text file at your domain root — like robots.txt — that gives AI assistants a structured summary of your website. What your business does, key content areas, how to navigate your site. It helps AI systems understand your business without crawling every page. If you want AI visibility, you need one.

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.

Weak 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.

Verdict

Below-average AEO readiness at 46/100 - multiple areas need attention. Key strengths include Schema.org Structured Data, Clean, Crawlable HTML, and Sitemap Completeness. Priority gaps: llms.txt File, Speakable Schema, and Owned Data Density. Topic coherence is 3/10, which caps the overall score at 50. Focusing content on core expertise areas is the single highest-impact improvement.

Creator Transparency: Show Who Wrote This and Why They Are Qualified

Anonymous content is untrusted content. AI engines check for author bylines, bio links, reviewer credits, and Person schema to decide whether a page comes from a credible creator. Creator Transparency measures how clearly your content identifies its authors and their qualifications.
