SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Link-building teams waste hours manually comparing backlink exports across competitors to find prospects, with no consistent way to rank which domains are worth pitching first.

Core Features & Use Cases

  • Gap Analysis Engine: Runs scripts/backlink_gap.py against your backlink CSV and 2-5 competitor CSVs to surface referring domains that link to competitors but not to you.
  • Priority Scoring & Quality Gates: Ranks prospects with a weighted score (0.40 DR + 0.25 link-overlap + 0.20 traffic + 0.15 topical relevance) and validates inputs through a four-gate scorecard covering data freshness, sample size, competitor coverage, and link-overlap signal.
  • Outreach-Ready Outputs: Produces a 30-prospect shortlist, broken-link replacement candidates, and three pre-filled outreach templates in the brand's voice.
  • Use Case: During a quarterly audit, export backlinks from Ahrefs for your domain and three competitors, then run the skill to get a ranked backlog of link targets and hand the shortlist to your digital PR workflow.

Quick Start

Run /digital-marketing-pro:backlink-gap for my brand using backlink CSV exports from my domain and three competitors to generate a ranked outreach prospect list.

Frequently Asked Questions about backlink-gap

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find websites that link to my competitors but not me?

Export backlink CSVs for your domain and at least two competitors from the same provider, then run the backlink-gap skill. It computes the set difference and ranks shared referring domains by DR, link overlap, traffic, and topical relevance.

How many competitors do I need for a backlink gap analysis?

Two competitors is the minimum for a meaningful link-overlap signal, and three to five focused competitors is the recommended range. A single competitor only shows who links to them, not who consistently links in your space.

Can I mix Ahrefs and Moz backlink exports in one analysis?

No. DR and DA metrics from different exporters are not comparable, and the script does not normalize across providers. Pick one backlink data provider per audit for consistent scoring.

Why did my backlink gap run return a needs_review status?

The quality scorecard failed one of four gates: input CSVs older than 90 days, fewer than 50 unique referring domains per input, only one competitor supplied, or fewer than 5 domains linking to multiple competitors. Re-pull fresh data or re-choose competitors in the same content space.

When should I not use backlink gap analysis?

Skip it when you only need raw backlink counts, which your backlink MCP provides directly, or when you need anchor-text analysis of your own profile, which belongs in a full SEO audit. It is built for prospect discovery, not profile health checks.
