This answer engine optimization tool scores one page on how ready it is to be quoted by ChatGPT, Perplexity and Google's AI Overviews. Enter a URL and it measures what it can check directly: whether robots.txt lets AI crawlers in, whether you have an llms.txt file, your structured data, question headings, lists and word count. An AI model then judges how quotable the opening text is. It is free and needs no signup.
How to use the answer engine optimization tool
- 1Type the address of the page you want AI answers to quote, such as a service page or a guide.
- 2Press Score, or hit Enter; the tool also reads your robots.txt and llms.txt, so give it a few seconds.
- 3Read the grade and the four bars: Structured data, AI crawler access, Answer formatting and Citability.
- 4Check Measured signals for anything marked as missing, such as no JSON-LD or a robots.txt that blocks AI crawlers.
- 5Read Questions this page can answer and Recommended AEO fixes, then change the page and score it again.
When to use it
- Customers tell you they asked ChatGPT for a recommendation, and you want to know if your page could be the answer.
- You wrote a guide or an FAQ page and want to check it is set out in a way AI tools can quote.
- You are not sure whether your robots.txt blocks GPTBot, ClaudeBot or PerplexityBot.
- A competitor keeps turning up in AI answers and you want to compare their page with yours.
Worked example
A homepage with strong structure and weak quotability
We scored our own homepage.
- URL to score
- https://searchblueprint.io
- Result
- B, 81/100
- Structured data
- 100
- AI crawler access
- 100
- Answer formatting
- 93
- Citability
- 42 (AI-judged)
- Structured data (JSON-LD)
- Organization, WebSite, FAQPage, SoftwareApplication (FAQ/QA detected)
- Content depth
- 6,075 visible words
- Recommended AEO fixes
- 1. Replace marketing claims with concrete definitions: Define what AEO/GEO means in 1-2 clear sentences before selling features
Everything the tool can measure is in place: AI crawlers are allowed, llms.txt exists, the FAQ schema is found and the page has lists, tables and three question headings. Citability at 42 is what holds the grade at B. The model read the opening text and found selling where it wanted a plain definition, a fair hit on a homepage, and its first fix is to define AEO in a sentence or two before the features. The model writes its questions and fixes fresh each run, so the wording changes if you score the page again.
How the score is built
| Part | Weight | What it checks |
|---|---|---|
| Structured data | 25% | JSON-LD on the page. FAQPage or QAPage scores highest, then HowTo and Article types. |
| AI crawler access | 20% | Whether robots.txt blocks GPTBot, ClaudeBot, PerplexityBot, CCBot, Google-Extended or anthropic-ai, plus a bonus for /llms.txt |
| Answer formatting | 25% | Headings phrased as questions, lists and tables, and a word count between 300 and 3,000 |
| Citability | 30% | An AI model's judgment of how quotable the title, headings and first 1,500 characters are |
Grades run A at 90 and up, B from 80, C from 70, D from 55 and F below that. If the model does not answer, Citability shows n/a and the other three parts carry the score.
