62# Backlink Analyzer
63 
64Analyzes backlink profiles for quality, risk, competitive gaps, and link-building opportunities.
65 
66## Quick Start
67 
68```
69Analyze backlink profile for [domain]
70```
71 
72```
73Find link building opportunities by analyzing [competitor domains]
74```
75 
76## Skill Contract
77 
78**Expected output**: a backlink report or delta summary plus the standard handoff summary for `memory/monitoring/`.
79 
80- **Reads**: current metrics, baselines, alert thresholds, and reporting context from [CLAUDE.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/CLAUDE.md) and the shared [State Model](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/references/state-model.md) when available.
81- **Writes**: a user-facing monitoring deliverable and reusable summary.
82- **Promotes**: significant changes, confirmed anomalies, and follow-up actions to `memory/open-loops.md` and `memory/decisions.md`.
83- **Primary next skill**: [domain-authority-auditor](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/cross-cutting/domain-authority-auditor/SKILL.md) when toxicity or authority concerns need formal scoring.
84 
85### Handoff Summary
86 
87> Emit the standard shape from [skill-contract.md §Handoff Summary Format](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/references/skill-contract.md).
88 
89## Data Sources
90 
91All integrations optional (see [CONNECTORS.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/CONNECTORS.md)). With tools, pull backlink profiles from ~~link database and competitor data from ~~SEO tool. Without tools, ask for backlink CSVs, referring domains, competitor domains, and link changes. Respect `robots.txt` and TOS per [SECURITY.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/SECURITY.md).
92 
93## Instructions
94 
95When a user requests backlink analysis:
96 
971. **Generate Profile Overview** — key metrics, link velocity, authority distribution, and profile health score.
982. **Analyze Link Quality** — top backlinks, link type mix, anchor text distribution, and geography.
993. **Identify Toxic Links** — risk indicators, links to review, and disavow recommendations.
1004. **Compare Against Competitors** — profile comparison, link intersection, and top linked competitor content.
1015. **Find Link Building Opportunities** — intersection prospects, broken links, unlinked mentions, resource pages, guest posts, and effort-vs-impact priorities.
1026. **Track Link Changes** — new and lost links, net change, and recovery priorities.
1037. **Generate Backlink Report** — executive summary, strengths, concerns, opportunities, competitive position, recommended actions, and KPIs.
104 
105> **Reference**: See [references/analysis-templates.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/monitor/backlink-analyzer/references/analysis-templates.md) for the compact output templates used in all seven steps.
106 
107### CITE Item Mapping
108 
109When running `domain-authority-auditor` after this analysis, the following data feeds directly into CITE scoring:
110 
111| Backlink Metric | CITE Item | Dimension |
112|----------------|-----------|-----------|
113| Referring domains count | C01 (Referring Domain Volume) | Citation |
114| Authority distribution (DA breakdown) | C02 (Referring Domains Quality) | Citation |
115| Link velocity | C04 (Link Velocity) | Citation |
116| Geographic distribution | C10 (Link Source Diversity) | Citation |
117| Dofollow/Nofollow ratio | T02 (Dofollow Ratio Normality) | Trust |
118| Toxic link analysis | T01 (Link Profile Naturalness), T03 (Link-Traffic Coherence) | Trust |
119| Competitive link intersection | T05 (Profile Uniqueness) | Trust |
120 
121## Example
122 
123Sample outcome: a link-intersection table, top immediate opportunities, and an estimated impact model. Keep the full structure in [references/analysis-templates.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/monitor/backlink-analyzer/references/analysis-templates.md).
124 
125## Tips for Success
126 
127Prioritize quality, monitor regularly, diversify anchors and link types, and disavow cautiously.
128 
129## Link Quality and Strategy Reference
130 
131> **Reference**: See [references/link-quality-rubric.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/monitor/backlink-analyzer/references/link-quality-rubric.md) for the scoring matrix, toxic-link criteria, benchmarks, and disavow guidance.
132 
133> **Reference**: See [references/outreach-templates.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/monitor/backlink-analyzer/references/outreach-templates.md) for outreach frameworks, subject lines, response benchmarks, follow-up sequences, and templates.
134 
135### Save Results
136 
137Ask "Save these results?" If yes, write `memory/monitoring/YYYY-MM-DD-<topic>.md` with headline finding, actions, and open loops. If toxic ratio exceeds 15%, recommend `domain-authority-auditor`.
138 
139## Reference Materials
140 
141- [Link Quality Rubric](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/monitor/backlink-analyzer/references/link-quality-rubric.md) — Quality and toxicity rubric
142- [Outreach Templates](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/monitor/backlink-analyzer/references/outreach-templates.md) — Outreach frameworks and examples
143 
144## Next Best Skill
145 
146Toxic ratio > 15% → [domain-authority-auditor](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/cross-cutting/domain-authority-auditor/SKILL.md). Otherwise → Terminal. Visited-set rule applies per [skill-contract.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/references/skill-contract.md).
