seo-backlinks — Backlink Analysis & Outreach Strategy

Backlink Profile Analysis

Key Metrics

Anchor Text Distribution

Ideal distribution to avoid over-optimization penalties:

Link Attribute Distribution

Competitor Backlink Discovery

Inspired by automated competitor backlink monitoring workflows.

Discovery Process

1. Identify competitors — 3-5 direct competitors + 2-3 aspirational
2. Fetch new backlinks — Weekly lookback window via Backlinks API
3. Quality filter — Apply minimum thresholds:

• DR ≥ 30 (adjustable by industry)
• Organic traffic ≥ 500/month
• Relevance score: same industry/topic
• Exclude known PBNs, link farms, directories

1. Gap analysis — Identify domains linking to competitors but not you
2. Prioritize — Rank by: authority × relevance × acquisition feasibility

Competitor Backlink Matrix

              | Your Site | Comp A | Comp B | Comp C |
|-------------|-----------|--------|--------|--------|
| Total Refs  |    450    |  1200  |   800  |   600  |
| DR 60+      |     45    |   180  |   120  |    80  |
| Common Refs |     --    |   120  |    95  |    78  |
| Unique Refs |     --    |   280  |   150  |   110  |
| Link Gap    |     --    |   280  |   150  |   110  |

Common Referring Domains

Domains linking to 2+ competitors but not you = highest priority prospects.

Outreach Strategy Generation

Strategy Types by Source

Outreach Email Template Structure

1. Subject line — Personalized, reference their content
2. Opening — Specific compliment about their work (not generic)
3. Value proposition — What's in it for them
4. The ask — Clear, specific, low-friction
5. Social proof — Brief credibility signal

Follow-up Cadence

Prioritization Formula

Priority Score = (DR / 100) × Relevance × (1 / Difficulty)

Where: Relevance = 0-1 topic match, Difficulty = 1(easy) to 5(hard)

Link Quality Scoring

Single Link Quality Score (0-100)

Toxic Link Indicators

• Gambling, adult, pharma sites linking without context
• PBN patterns (same IP range, thin content, reciprocal networks)
• Paid link networks (footer-wide, sidebar widgets)
• Redirect chains (301 → 301 → target)
• Foreign language sites with no topical relevance

Internal Link Analysis

Orphan Page Detection

Pages with zero internal links pointing to them — invisible to crawlers navigating via links.

Link Depth Analysis

Internal Link Optimization

• Important pages should have 5+ internal links pointing to them
• Use descriptive anchor text (not "click here")
• Distribute PageRank from high-authority pages to target pages
• Create topic clusters: pillar page ↔ cluster pages with bidirectional links

Link Building ROI Projection

By Strategy

Monthly Target Setting

Based on competitive gap and current growth rate:

• Aggressive: Close 50% of competitor gap in 6 months
• Moderate: Match competitor link velocity
• Maintenance: Preserve current position, focus on quality
