Free AIO Citation Check

Check whether your page is structured to be cited by AI search (ChatGPT, Perplexity, AI Overview). It generates improvement code for what's missing.

What is AIO Citation Check?

A free tool that diagnoses whether AI search engines can readily cite your page as a source — across direct answers, extractable structure, structured data, and E-E-A-T. It scores AI-citability out of 100, not search ranking.

Four factors that decide AI citation readiness

We diagnose the structural signals AI looks at when choosing a source to cite.

Direct answer at the top

Most AI citations are extracted from the top of the page. We check whether the conclusion to the search intent is up front.

Extractable structure

Bullet lists, numbered steps, and comparison tables make it easy for AI to extract key points. We rate their density.

Question-style headings

Headings that match search intent get cited more. We diagnose the share of question-style h2/h3.

Trust signals

Author, dates, source links, and structured data are central to whether AI deems a source safe to cite.

Why optimize for AI citation

As ChatGPT and Google AI Overview generate answers, whether AI cites you as a source is a new traffic channel beyond ranking. AI tends to pick pages with clear conclusions, structured content, and trust signals as sources.

AIO Citation Check makes that citability visible from a structural standpoint and offers copy-paste improvement code for each missing element. Paired with SEO Check (for Google ranking), it lifts traffic from both search and AI search.

How to improve AI citation readiness (4 steps)

Whether AI search (ChatGPT, Perplexity, Google AI Overview) cites you is driven by structural factors separate from ranking. The following four steps shape a page AI can readily extract as a source.

  1. 1

    Put a direct answer to the search intent at the top

    Right after the h1, state the conclusion to the expected search intent in 1-2 sentences (around 40-120 chars). AI search tends to extract a concise conclusion from the top of the page when citing a source.

  2. 2

    Structure steps and comparisons

    Use numbered lists for steps, bullets for key points, and tables for comparing plans, tools, or methods. AI extracts key points more accurately from structured elements than from prose.

  3. 3

    Phrase headings as questions

    Phrase h2/h3 as questions that match expected queries — "What is …", "How to …", "Why …". AI is more likely to cite text under headings that directly answer a question.

  4. 4

    Add trust signals and structured data

    Show author info, published/modified dates, and source links, and implement Article/FAQPage/HowTo JSON-LD. E-E-A-T and machine-readability are the foundation AI uses to judge whether a source is safe to cite.

How it differs from SEO Check, Structured Data, and llms.txt

AIO Citation Check is the entry point that looks holistically at AI citability. Deep-diving each element on its own is handled by the dedicated tools.

An honest note: This tool diagnoses whether your structure is citable by AI — it does not monitor whether you are actually cited by ChatGPT or AI Overview. Because AI citation is decided by each service's private logic, improving structure raises the probability of being cited but does not guarantee it.

FAQ

How is AIO Citation Check different from SEO Check?
SEO Check is an overall audit aimed at improving Google rankings. AIO Citation Check diagnoses whether your page is structured to be cited as a source by AI search engines like ChatGPT, Perplexity, and Google AI Overview. The difference is that it evaluates citability by AI rather than search ranking.
Can it tell whether I'm actually cited in AI Overview?
No. This tool diagnoses whether your structure is citable by AI — it does not monitor whether you are actually cited by ChatGPT or AI Overview. Because AI citation is decided by each service's private logic, improving structure raises the probability of being cited but does not guarantee it.
What kind of improvement code is generated?
Depending on the missing elements, it generates a lead-paragraph template for a direct answer, FAQPage/Article JSON-LD, author structured data, and HTML templates for comparison tables and lists — all ready to copy and paste into your page.
Can I check llms.txt and structured data in detail?
AIO Citation Check is an overall diagnosis that includes these. To deep-dive each element on its own, use the dedicated llms.txt Checker and Structured Data Check. The AIO results also link out to those tools.
How much can I use for free?
