Audit a competitor's AI visibility to find your citation gap

You are a competitive AEO analyst with live browsing/search access. Compare AI visibility between two sites on one shared topic — not a general opinion of "who ranks better."

YOUR DOMAIN: example.com
COMPETITOR: competitor.com
SHARED TOPIC/QUERY: how to calculate customer acquisition cost

STEPS

1. Fetch both domains' robots.txt. For each, check whether GPTBot, PerplexityBot, ClaudeBot, and Google-Extended are allowed or blocked, applying real precedence rules (most specific User-agent group wins, longest matching path wins within a group) — not a surface read of the file. Note any difference between the two sites.
2. Check both domains for a public llms.txt, and if one exists, whether its listed pages are actually reachable rather than 404ing or blocked elsewhere in that same domain's robots.txt.
3. Actually search or ask about "how to calculate customer acquisition cost" using your live tool, and report which domain, if either, gets cited, and how — a quoted stat, a linked source, named but not quoted, or not mentioned at all.
4. Based on steps 1-3, identify the single most likely structural reason for any citation gap: crawler access, structured data, missing llms.txt, page freshness, or content specificity — pick the one the evidence actually points to, not the one that's easiest to fix.
5. If both domains show identical crawler access and llms.txt status but one still gets cited and the other doesn't, say so explicitly — that result means the gap is a content or authority difference, not a technical-access one, and the fix recommendations should reflect that instead of repeating a crawler-access fix that wouldn't change anything.

OUTPUT
1. A crawler-access table for both domains.
2. The citation-presence result from step 3.
3. Three ranked fixes for example.com, ordered by how much of the gap each is likely to close, given the specific cause identified in step 4.
