seo-backlinks — Backlink Analysis & Outreach Strategy

Backlink Profile Analysis

Key Metrics

Metric	What It Measures	Healthy Range
Referring Domains	Unique linking domains	Growth >5%/month
Domain Rating (DR)	Site authority (Ahrefs 0-100)	Industry-dependent
Domain Authority (DA)	Site authority (Moz 0-100)	Industry-dependent
Authority Score (AS)	Site authority (SEMrush 0-100)	Industry-dependent
Link Velocity	New links per month	Steady growth, no spikes
Toxic Score	Harmful link percentage	<5% of total profile

Anchor Text Distribution

Ideal distribution to avoid over-optimization penalties:

Anchor Type	Target %	Example	Risk if Over
Branded	35-45%	"Acme Corp", "acme.com"	Low risk
Naked URL	15-25%	"https://acme.com/page"	Low risk
Generic	10-15%	"click here", "read more"	Low risk
Partial match	10-15%	"best CRM for startups"	Medium risk
Exact match	5-10%	"CRM software"	High risk if >15%
LSI/Related	5-10%	"customer management tool"	Low risk

Link Attribute Distribution

Attribute	What It Means	Ideal Mix
Dofollow	Passes link equity	60-80%
Nofollow	No equity, still valuable for traffic	15-30%
UGC	User-generated (forums, comments)	5-10%
Sponsored	Paid/affiliate links	<5%

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
4. Gap analysis — Identify domains linking to competitors but not you
5. 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

Strategy	Best For	Success Rate	Cost	Time
Guest Posting	Authority building	10-25%	Medium	2-4 weeks
Resource Page	Niche directories	15-30%	Low	1-2 weeks
Broken Link	Quick wins	5-15%	Low	1 week
Skyscraper	Competitive niches	5-10%	High	4-8 weeks
HARO/Connectively	Brand mentions	3-8%	Low	Ongoing
Digital PR	Brand authority	2-5%	High	4-12 weeks
Unlinked Mentions	Easy wins	20-40%	Low	1 week

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

Attempt	Timing	Approach
Initial	Day 0	Full pitch with value prop
Follow-up 1	Day 5	Brief reminder, add new angle
Follow-up 2	Day 10	Different value proposition
Follow-up 3	Day 21	Final attempt, FOMO or new hook

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)

Factor	Weight	Scoring
Source DR/DA	30%	DR 0-100 mapped directly
Topical relevance	25%	0=unrelated, 50=adjacent, 100=exact
Link placement	20%	Editorial/body=100, sidebar=40, footer=20
Source traffic	15%	Log scale: 0=no traffic, 100=10K+
Dofollow status	10%	Dofollow=100, Nofollow=50, Sponsored=25

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

Depth	Description	SEO Impact
1 click	Linked from homepage	Highest crawl priority
2 clicks	Linked from main nav pages	Good visibility
3 clicks	Linked from category/section pages	Moderate
4+ clicks	Deep in site hierarchy	Low — may be under-crawled

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

Strategy	Avg Cost/Link	Success Rate	Links/Month	DR Impact
Guest Post	$150-500	15%	2-5	+0.5-1
Broken Link	$50-100	10%	3-8	+0.3-0.5
HARO	$0-50	5%	1-3	+0.5-2
Digital PR	$500-2000	3%	1-2	+1-3
Unlinked Mentions	$0	30%	2-5	+0.2-0.5

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
