Backlink Analyzer

Use when analyzing backlink profiles, link authority, toxic links, link-building opportunities, or competitor link gaps. 外链分析/反向链接

Security Scan

The skill is an instruction-only backlink analysis helper whose requested resources and actions align with its declared purpose and it does not ask for extraneous credentials or installs.

Purpose & Capability

The name/description (backlink analysis, toxic links, opportunities) aligns with the SKILL.md content and the included templates. There are no unexpected required binaries, env vars, or installs that would be unrelated to SEO/backlink analysis.

Instruction Scope

Instructions are scoped to collecting backlink data (via optional connectors or user-uploaded CSVs), analysing link quality, identifying toxic links, comparing competitors, and producing reports/templates. The SKILL.md references reading repository documents (CLAUDE.md, state model) and writing standard agent memory files (memory/open-loops.md, memory/decisions.md) which is consistent with producing and tracking analysis. It does not direct the agent to read arbitrary system files, secret env vars, or post data to unexpected external endpoints.

Install Mechanism

No install spec and no code files — instruction-only — so nothing will be downloaded or written to disk by an installer. This is the lowest-risk installation profile.

Credentials

The skill declares no required environment variables, credentials, or config paths. Where external SEO tool connectors are optional, the SKILL.md sensibly asks for connectors or CSV uploads; any API keys would be provided only if the user opts to connect tools. No unrelated credentials are requested.

Persistence & Privilege

The skill writes analysis outputs and promotes actions into agent memory files (open-loops/decisions), which is appropriate for a reporting/monitoring skill. always:false (not force-installed) and normal autonomous invocation settings are used. Users should be aware that analyses and recommendations will be saved in the agent's memory files per the skill contract.

Assessment

This skill appears coherent and low-risk: it’s instruction-only, has no installers, and does not request secrets. Before installing, consider: 1) If you connect external SEO tools, only supply scoped API keys and verify which connector endpoints will be used. 2) The skill will write analysis summaries to agent memory (open-loops/decisions); avoid feeding sensitive or personally identifiable data in uploads if you do not want it stored. 3) Outreach templates are provided but the skill does not itself send emails — confirm your agent/tooling won't autonomously perform outreach without explicit consent. If you want extra assurance, review the CONNECTORS.md (if present) to see how optional integrations behave and which endpoints they call.

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 and the shared State Model when available.
• Writes: a user-facing monitoring deliverable and reusable summary.
• Promotes: significant changes, confirmed anomalies, and follow-up actions to memory/open-loops.md and memory/decisions.md.
• Primary next skill: domain-authority-auditor when toxicity or authority concerns need formal scoring.

Handoff Summary

Emit the standard shape from skill-contract.md §Handoff Summary Format.

Data Sources

All integrations optional (see 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.

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 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.

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 for the scoring matrix, toxic-link criteria, benchmarks, and disavow guidance.

Reference: See 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.

• Outreach Templates — Outreach frameworks and examples

Next Best Skill

Toxic ratio > 15% → domain-authority-auditor. Otherwise → Terminal. Visited-set rule applies per skill-contract.md.
