Subdomain Analysis

Map a domain's subdomain ecosystem. Which subdomains exist, what each ranks for, where they overlap, and whether the structure is healthy or fragmented. Output: an ownership map (which topic is owned by which subdomain), a fragmentation report, and recommendations for consolidate / split / leave alone.

Prerequisites

• SE Ranking MCP server connected.
• User provides: a target root domain (e.g. example.com). The skill discovers subdomains automatically.
• Optional: --limit N to cap the number of subdomains analysed (default: top 10 by ranked keyword count).

Process

1. Validate & preflight
   • Normalise root domain (no protocol, no www.).
   • DATA_getCreditBalance — surface remaining credits. Subdomain analysis is N × ~5 calls; cost scales with subdomain count.
