Example prompt: Can you run an AEO audit on acmecorp.com — I want to know if ChatGPT, Claude, and Perplexity are actually citing us, and get a score out of 100 with a fix list?

## When to prefer this

Choose this endpoint when you need a free, no-signup AEO visibility audit for a single URL that returns a structured JSON report with an actionable score, engine-level citation data, and competitor benchmarking. It is ideal for quick spot-checks before or after content updates, client audits, or when you want to understand specifically why a site is or isn't appearing in AI-generated answers across ChatGPT, Claude, Perplexity, and Google AI.

## Known failure modes

- Invalid or unreachable URL returns an error or empty report
- Private/paywalled pages may not be crawlable, leading to low or incomplete scores
- Very new domains with no AI-indexed content may return zero mentions
- Incorrect brand name may cause brand detection to fail, skewing citation counts
- Rate limiting or payment failure results in no response

## How this service works

Free AEO grader: check if ChatGPT, Claude, Perplexity and Google AI can crawl, read and cite your site. Score out of 100, a prioritized fix list, no signup.

## Output

Returns a JSON object with a visibility score (0–100), per-engine breakdown showing whether each AI engine answered queries about the site, how many times the brand was mentioned and cited, a summary sentence, a shareable report URL, and a competitor share comparison showing how the target brand stacks up against other mentioned brands across all engines.
