///ARTICFLY SYSTEM UTILITY

RAO Checker

Evaluate your content's structure to determine if AI engines (ChatGPT, Gemini, Perplexity) can understand and recommend your brand. Enter a target article URL.

///WHY RAO

AI search is 60% of B2B research. Is your content cite-able?

In 2023, optimizing for Google was enough. By the end of 2025, that stopped being true. About 60% of B2B buyers now consult an AI engine during the research phase of a purchase. If ChatGPT, Gemini, Perplexity, or Google AI Overviews never cite your articles, that 60% is lost before they ever see your domain.

AI engines do not pick citations the way Google picks rankings. The signal sets overlap, but the weights are different. FAQ schema, direct-answer paragraphs, definition sentences, and question-style headings carry far more weight for AI citation than they do for blue-link ranking. Most articles that rank #1 on Google score below 40 on RAO, they are invisible to AI.

This RAO Checker runs 10 deterministic checks against any article URL and gives you a 0-100 score plus a prioritized fix list. Free, no signup, no card. Use it on your top-ranking articles to find the AI-citation gap and close it.

///THE 10 SIGNALS

Every signal AI engines use to decide what to cite

Direct-answer paragraph (40-80 words)
AI engines extract the first paragraph as the answer snippet. A clear opening means direct citation, a buried answer means no citation.
Question-style headings
Headings that ask the user's actual question ("What is RAO?") match the prompt format. AI engines cite them at 3-5x the rate of statement-style headings.
FAQPage schema
FAQPage JSON-LD is the single strongest signal for AI citation. Google AI Overviews and Perplexity heavily prefer FAQ-marked content.
Definition sentences ("X is Y")
AI engines love clear definitions for "what is X" queries. One well-phrased definition sentence can land you the citation.
Numeric facts (≥3 per article)
Concrete numbers make content factually grounded and quotable. 5-7 numeric facts in an article correlates with 2x citation rate.
Bullet and numbered lists
Lists are highly extractable, AI engines preferentially cite list-formatted content because it maps cleanly to the answer format.
Comparison tables
Tables are first-class citations for "best X" and "X vs Y" queries. AI engines extract row data directly into their answers.
Author byline with E-E-A-T
AI engines (especially Google AI Overviews) heavily weight authorship signals. Real bylines with author bio outperform anonymous content by 4-6x.
Publish and updated dates
AI engines prefer fresh content. Articles without visible dates are assumed stale and ranked lower for citation eligibility.
TL;DR or summary section
TL;DR blocks are designed to be quoted, AI engines treat them as direct citation candidates and often quote them verbatim.
///FIX ORDER

The fastest 30 minutes you can spend on AI citation

Most articles fixable to RAO 80+ in 30 minutes. Fix order matters:

  1. Add FAQPage schema. Single highest-impact change. Identify 4-8 questions your article answers, mark them with FAQPage JSON-LD. 15-minute job.
  2. Rewrite the opening paragraph as a direct answer. First 60-80 words should directly answer "what is X" or "how does Y work". No setup paragraph, no context detour.
  3. Convert 30%+ of headings to question form. "How RAO works" becomes "How does RAO work?". Matches prompt format, improves citation rate.
  4. Add a TL;DR or Summary block. 3-5 bullet points at the top of the article. AI engines often quote these verbatim.
  5. Surface the author and dates. Add author byline near the H1, publish + updated dates near the byline. E-E-A-T signals carry weight.

///FAQ

Frequently asked questions

What is RAO and how does it differ from SEO?

RAO stands for Retrieval-Augmented Optimization, also called AEO (Answer Engine Optimization) or GEO (Generative Engine Optimization). It is the practice of optimizing content so AI engines (ChatGPT, Perplexity, Google AI Overviews, Claude) cite it in their answers. SEO optimizes for blue-link rankings on Google. RAO optimizes for being the answer the AI gives. Same content, two different scoring systems.

Why does RAO matter in 2026?

About 60% of B2B buyers now consult an AI engine during the research phase of a purchase. If your article ranks #1 on Google but no AI engine cites it, you lose that 60%. AI search traffic is the fastest-growing segment of organic discovery, growing 30-40% per quarter while traditional search stays flat.

Which AI engines does the checker test for?

ChatGPT (OpenAI), Gemini and Google AI Overviews (Google), Perplexity, Claude (Anthropic), and Microsoft Copilot. All six use overlapping signal sets, so a high RAO score correlates with citation rates across all of them. We are not affiliated with any of these engines, the scoring is based on observed citation patterns from public research and our own corpus tests.

How accurate is the RAO scoring?

The checker runs 10 deterministic signals against your HTML. Same article, same score, every time. It does not predict whether a specific AI engine will cite your specific article tomorrow, citation depends on the user's prompt, the engine's retrieval index, and your domain authority. What the score predicts is your structural eligibility to be cited. Articles scoring above 80 are cited 3-5x more often than articles scoring below 50.

Will fixing every RAO signal guarantee AI citations?

No, but it removes every technical blocker. Citation rate also depends on brand authority (do AI engines trust your domain?), topical depth (do you cover the topic better than the alternative?), and freshness (is your article newer than competitors?). RAO is the foundation, like technical SEO. Build on top with brand-building and topical authority.

How is this different from your Article Audit tool?

Article Audit scores 33 signals across both SEO and AEO/RAO, two scores side-by-side, full content audit. This RAO Checker focuses exclusively on the 10 strongest RAO signals for a faster, narrower check. Use RAO Checker when you only care about AI citation. Use Article Audit when you want both SEO and AEO scores.

Does the checker work for non-English content?

Yes. The structural signals (FAQ schema, heading format, lists, tables, author byline, dates) work in any language. Definition detection works for Polish, German, French, Spanish, Italian. AI engines themselves are multilingual, RAO works the same across languages.

Are AI citations actually traffic?

Yes, but with a different shape than blue-link traffic. AI citations send fewer raw visitors than a Google #1 ranking, but the visitors who do click have already pre-qualified through the AI summary. Conversion rates from AI-citation traffic run 2-3x higher than from organic blue-link traffic. Plus, brand mentions inside AI answers build awareness even without a click.
