SEO Off-Page: Backlink Analysis

Guides backlink profile analysis: assessing quality, identifying issues, and planning improvements.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Scope (Off-Page SEO)

Backlink audit: Analyze profile; toxic links; competitive analysis
Authority Score: Monitor domain/page authority; referring domains

Initial Assessment

Identify:

Domain: Site to analyze
Tool access: SEO tools (e.g. Ahrefs, Semrush) or free alternatives
Goals: Audit for issues, competitive analysis, or growth planning

Key Metrics

Metric	Meaning
Referring domains	Number of unique sites linking
Backlinks	Total number of links
Domain Rating (DR) / Domain Authority (DA)	Domain strength score
Anchor text distribution	Mix of branded, generic, exact match
Link velocity	Rate of new links over time

Analysis Framework

1. Quality Assessment

Relevance: Do links come from related niches?
Authority: Are referring domains trusted?
Context: Editorial vs. footer/sidebar links?
Anchor text: Natural or over-optimized?

2. Risk Signals

Signal	Action
Toxic links	Consider disavow (use cautiously)
Spammy anchors	Diversify anchor text naturally
Link schemes	Remove or disavow
Sudden spike	Investigate; may trigger penalty

3. Competitive Comparison

Compare backlink profile to competitors
Identify link gaps (sites linking to competitors but not you)
Find link opportunities from competitor backlinks
See competitor-research for full methodology

Disavow File

Use only when necessary (manual penalty, toxic links)
Submit via Google Search Console (see google-search-console for Links report and disavow submission)
Caution: Over-disavowing can harm; use sparingly
References: Google Disavow
