# Backlink Analyzer
Analyzes backlink profiles for quality, risk, competitive gaps, and link-building opportunities.
## Quick Start
```
Analyze backlink profile for [domain]
```
```
Find link building opportunities by analyzing [competitor domains]
```
## Skill Contract
**Expected output**: a backlink report or delta summary plus the standard handoff summary for `memory/monitoring/`.
- **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.
- **Writes**: a user-facing monitoring deliverable and reusable summary.
- **Promotes**: significant changes, confirmed anomalies, follow-up actions, and pending decisions to `memory/open-loops.md`.
- **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.
### Handoff Summary
> 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).
## Data Sources
All 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).
## Instructions
When a user requests backlink analysis:
1. **Generate Profile Overview** — key metrics, link velocity, authority distribution, and profile health score.
2. **Analyze Link Quality** — top backlinks, link type mix, anchor text distribution, and geography.
3. **Identify Toxic Links** — risk indicators, links to review, and disavow recommendations.
4. **Compare Against Competitors** — profile comparison, link intersection, and top linked competitor content.
5. **Find Link Building Opportunities** — intersection prospects, broken links, unlinked mentions, resource pages, guest posts, and effort-vs-impact priorities.
6. **Track Link Changes** — new and lost links, net change, and recovery priorities.
7. **Generate Backlink Report** — executive summary, strengths, concerns, opportunities, competitive position, recommended actions, and KPIs.
> **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.
### CITE Item Mapping
When running `domain-authority-auditor` after this analysis, the following data feeds directly into CITE scoring:
| Backlink Metric | CITE Item | Dimension |
|----------------|-----------|-----------|
| Referring domains count | C01 (Referring Domain Volume) | Citation |
| Authority distribution (DA breakdown) | C02 (Referring Domains Quality) | Citation |
| Link velocity | C04 (Link Velocity) | Citation |
| Geographic distribution | C10 (Link Source Diversity) | Citation |
| Dofollow/Nofollow ratio | T02 (Dofollow Ratio Normality) | Trust |
| Toxic link analysis | T01 (Link Profile Naturalness), T03 (Link-Traffic Coherence) | Trust |
| Competitive link intersection | T05 (Profile Uniqueness) | Trust |
## Example
Sample 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).
## Tips for Success
Prioritize quality, monitor regularly, diversify anchors and link types, and disavow cautiously.
## Link Quality and Strategy Reference
> **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.
> **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.
### Save Results
Ask "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`.
## Reference Materials
- [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
- [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
## Next Best Skill
Toxic 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).
