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-.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).
