- Goals: Audit for issues, competitive analysis, or growth planning
Key Metrics

| Backlinks | Total number of links |
| Domain Rating (DR) / Domain Authority (DA) | Domain strength score |
| Anchor text distribution | Mix of branded, generic, exact match |
| Link velocity | Rate of new links over time |
Analysis Framework
1. Quality Assessment
- Relevance: Do links come from related niches?
- Authority: Are referring domains trusted?
- Context: Editorial vs. footer/sidebar links?
- Anchor text: Natural or over-optimized?
2. Risk Signals
| Signal | Action |
|--------|--------|
| Toxic links | Consider disavow (use cautiously) |
| Spammy anchors | Diversify anchor text naturally |
| Link schemes | Remove or disavow |
| Sudden spike | Investigate; may trigger penalty |
3. Competitive Comparison
- Compare backlink profile to competitors
- Identify link gaps (sites linking to competitors but not you)
- Find link opportunities from competitor backlinks
- See competitor-research for full methodology
Disavow File
- Use only when necessary (manual penalty, toxic links)
- Submit via Google Search Console (see google-search-console for Links report and disavow submission)
