Analysis Modes

1. Backlink Profile Analysis

Get a comprehensive overview of a domain's backlink profile:

Input: domain (e.g., "example.com")
Output:
- Total backlinks count
- Referring domains count
- Domain rank (0-1000)
- Spam score (0-100)
- Dofollow vs nofollow ratio
- Top referring domains
- Anchor text distribution
- New/lost links trend

2. Competitor Comparison

Compare your backlink profile against competitors:

Input: [your-domain, competitor1, competitor2, ...]
Output:
- Side-by-side metrics comparison
- Unique referring domains per site
- Shared referring domains
- Gap opportunities

3. Link Gap Analysis

Find domains that link to competitors but not to you:

Input: [your-domain, competitor1, competitor2]
Output:
- Domains linking to competitors but not you
- Sorted by authority/relevance
- Prioritized outreach list

This is the most valuable analysis for link building strategy.

4. Toxic Link Detection

Identify potentially harmful backlinks:

Input: domain
Output:
- Links from high spam score domains
- Suspicious anchor text patterns
- Low-quality referring domains
- Disavow candidates

5. Anchor Text Analysis

Analyze anchor text distribution:

Input: domain
Output:
- Anchor text distribution chart
- Brand vs keyword vs generic ratio
- Over-optimized anchor warnings
- Natural vs unnatural patterns

Healthy distribution guidelines:

Brand anchors: 30-40%
Naked URLs: 20-30%
Generic (click here, etc.): 15-20%
Keyword-rich: 10-15% (over 20% = warning)
LSI/related: 5-10%

Interpretation Guidelines

Domain Rank (0-1000)

0-100: Low authority
100-300: Moderate authority
300-500: Good authority
500-700: Strong authority
700-1000: Excellent authority

Spam Score (0-100)

0-10: Clean profile
10-30: Low risk
30-60: Moderate risk (review needed)
60-100: High risk (cleanup recommended)

Red Flags

Sudden spike in backlinks (potential negative SEO)
High percentage of nofollow links from unique domains
Anchor text dominated by exact-match keywords
Links from irrelevant industries/topics
Many links from same IP range or C-class

Link Building Prioritization

When generating outreach lists from link gap analysis:

Tier 1 (High Priority)

Domain rank > 500
Relevant to your industry
Editorial links (not directories)

Tier 2 (Medium Priority)

Domain rank 200-500
Related industry or topic
Resource pages, roundups

Tier 3 (Low Priority)

Domain rank < 200
Directories, forums
Comment sections
