# Backlink Profile Analysis

## Source Detection

Before analysis, detect available data sources:

1. **DataForSEO MCP** (premium): Check if `backlinks_summary` tool is available
2. **Moz API** (free signup): `"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run backlinks_auth.py --check moz --json`
3. **Bing Webmaster** (free signup): `"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run backlinks_auth.py --check bing --json`
4. **Keywords Everywhere** (free signup; domain rank plus referring-domain count): `"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run backlinks_auth.py --check keywordseverywhere --json`
5. **Common Crawl** (always available): Domain-level graph with PageRank
6. **Verification Crawler** (always available): Checks if known backlinks still exist

Run `"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run backlinks_auth.py --check --json` to detect all sources at once.

If no sources are configured beyond the always-available tier:
- Still produce a report using Common Crawl domain metrics
- Suggest: "Run `/seo backlinks setup` to add free Moz and Bing API keys for richer data"
