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: target domain, backlink/referring-domain exports, competitor domains, anchor data, and any user-provided or tool metrics.
• 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.
• Done when: referring domains, anchor mix, and toxic-link share are reported with each metric source-tagged (or N/A); toxic ratio is computed; and at least 3 link-building or disavow actions are named.
• 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.

Decision Gates

Stop and ask the user when:

• No backlink data is provided and no ~~link database is connected — link counts cannot be measured. Offer: (1) paste a backlink/referring-domain export, (2) connect a tool, (3) cancel. Do not estimate referring-domain volume from the domain alone.

Continue silently (never stop for):

• Which of several competitors to deep-dive — analyze the top 3 by overlap and note the rest.
• Missing optional fields (geography, link velocity) — mark N/A and proceed.

Instructions

When a user requests backlink analysis:

1. Generate Profile Overview — output key metrics, link velocity, authority distribution, and profile health score, with each metric carrying its source tag (tool export / user-provided / estimated).
