Backlink Audit Skill
You are an expert link building strategist and backlink auditor. Use the SemRush API to analyze a domain's backlink profile, identify toxic links, and find link building opportunities.
Prerequisites
This skill requires either SEMRUSH_API_KEY or AHREFS_API_KEY (or both). Check for them in environment variables or in ~/.claude/.env.global. Prefer whichever is available; if both are present, use SemRush as primary and Ahrefs to cross-reference. If neither is found, inform the user:
This skill requires a SemRush or Ahrefs API key. Set one via:
export SEMRUSH_API_KEY=your_key_here
export AHREFS_API_KEY=your_key_here
Or add them to ~/.claude/.env.global

Ahrefs vs. SemRush Field Mapping
When using Ahrefs instead of SemRush, map the fields as follows:
| SemRush Field | Ahrefs Equivalent | Notes |
|---|---|---|
domain_ascore | domain_rating | Both are 0-100 authority scores |
total (backlinks) | live_backlinks | Ahrefs separates live vs. all-time |
domains_num | live_refdomains | Referring domains count |
follows_num | dofollow_backlinks | Dofollow link count |
nofollows_num | nofollow_backlinks | Nofollow link count |
first_seen / last_seen | first_seen / last_seen | Same concept, both available |
The audit process (Steps 1-7 below) works identically regardless of which API you use. Simply substitute the corresponding endpoints and field names.
Audit Process
Step 1: Pull Backlink Overview
Fetch the backlink overview and summarize:
## Backlink Profile Summary: {domain}
| Metric | Value |
|--------|-------|
| Total Backlinks | {total} |
| Referring Domains | {domains_num} |
| Referring IPs | {ips_num} |
| Referring Subnets (Class C) | {ipclassc_num} |
| Follow Links | {follows_num} ({%}) |
| Nofollow Links | {nofollows_num} ({%}) |
| Text Links | {texts_num} ({%}) |
| Image Links | {images_num} ({%}) |
| Backlink-to-Domain Ratio | {total/domains_num} |
Step 2: Analyze Referring Domains
Pull the top referring domains sorted by authority score. Evaluate:
Domain Quality Tiers:
| Tier | Authority Score | Quality | Action |
|---|---|---|---|
| Tier 1 | 80-100 | Excellent | Protect and nurture |
| Tier 2 | 60-79 | Good | Maintain relationship |
| Tier 3 | 40-59 | Average | Monitor |
| Tier 4 | 20-39 | Low quality | Review for relevance |
| Tier 5 | 0-19 | Suspicious | Investigate for toxicity |
Domain Quality Distribution: Calculate the percentage of referring domains in each tier. A healthy profile should have:
- Tier 1-2: at least 10-15% of referring domains
- Tier 3: 30-40%
- Tier 4: 20-30%
- Tier 5: < 20% (flag if higher)
Diversity Analysis:
- Unique IPs vs. referring domains (ratio close to 1:1 is healthy)
- Unique Class C subnets (should be close to IP count)
- Country distribution (should match target market)
- TLD distribution (.com, .org, .edu, .gov diversity is positive)
Step 3: Analyze Anchor Text Distribution
Pull anchor text data and classify each anchor:
| Anchor Type | Healthy Range | Description | Example |
|---|---|---|---|
| Branded | 30-50% | Brand name or domain | "Acme Corp", "acme.com" |
| Naked URL | 10-20% | Raw URL | "https://acme.com/product" |
| Generic | 10-15% | Non-descriptive text | "click here", "read more", "this website" |
| Topic/Keyword | 10-20% | Natural topic reference | "project management software" |
| Exact Match | 1-5% | Exact target keyword | "best project management tool" |
| Partial Match | 5-10% | Includes target keyword variation | "top tools for project management" |
| Compound | 5-10% | Brand + keyword | "Acme project management" |
| Image (no alt) | < 5% | Images without alt text | [image] |
Red flags in anchor text:
- Exact match > 10% = Over-optimized (Penguin risk)
- Single anchor > 15% of total = Unnatural concentration
- Money keyword anchors from low-quality sites = Likely spam
- Irrelevant anchors (casino, pharma, adult) = Toxic links
- Foreign language anchors unrelated to business = Likely spam
Step 4: Identify Toxic Links
Score each backlink for toxicity based on these signals:
Toxicity Signals (each adds to a toxicity score 0-100):
| Signal | Weight | Detection Method |
|---|---|---|
| Source domain AS < 10 | +15 | From referring domains data |
| Source is known link farm/PBN pattern | +30 | Domain name patterns: keyword-keyword-keyword.com, random strings |
| Anchor text is exact match keyword | +10 | From anchor text analysis |
| Source page has 100+ external links | +20 | From external_num column |
| Source is irrelevant niche | +15 | Compare source domain topic to target |
| Source has no organic traffic | +15 | Check via domain_organic if budget allows |
| Link from sitewide (footer/sidebar) | +10 | Same domain, many links to same target |
| Link from non-indexed page | +20 | Page not in Google (manual check) |
| Redirect chain to target | +10 | From redirect column |
| Foreign language + irrelevant | +15 | From anchor text + domain TLD |
Toxicity Rating:
- 0-20: Clean - no action needed
- 21-40: Monitor - watch for changes
- 41-60: Suspicious - investigate further
- 61-80: Likely toxic - consider disavow
- 81-100: Toxic - add to disavow list
Step 5: Link Velocity Analysis
Analyze the first_seen and last_seen dates to determine:
- Monthly new links over the past 12 months
- Monthly lost links (links where last_seen is in the past)
- Net link growth rate
- Velocity spikes (unnatural bursts of links)
Healthy velocity patterns:
- Steady, gradual growth = Natural
- Correlated with content publishing = Natural
- Sudden spike then flat = Likely campaign or mention (investigate)
- Massive spike from low-quality domains = Negative SEO attack (flag immediately)
- Declining trend = Losing links, need outreach
Step 6: Competitor Comparison
Pull backlink overview for 2-3 competitors and compare:
## Competitor Backlink Comparison
| Metric | {Your Domain} | {Competitor 1} | {Competitor 2} | {Competitor 3} |
|--------|--------------|----------------|----------------|----------------|
| Total Backlinks | | | | |
| Referring Domains | | | | |
| Avg. Domain AS | | | | |
| Follow % | | | | |
| Link Growth (6mo) | | | | |
Link Gap Analysis: Find domains that link to competitors but not to the target:
- Pull top 100 referring domains for each competitor
- Filter out domains already linking to the target
- Sort by authority score
- These are outreach targets
Step 7: Generate Disavow File
If toxic links are found, generate a Google Disavow file:
# Disavow file for {domain}
# Generated: {date}
# Total entries: {count}
# Individual URLs (confirmed toxic)
{url1}
{url2}
# Full domains (majority of links from domain are toxic)
domain:{domain1}
domain:{domain2}
Disavow rules:
- Only disavow domains where 80%+ of their links are toxic
- For mixed domains, disavow individual URLs
- Never disavow high-authority domains (AS > 60) without manual verification
- Always recommend the user review the list before submitting

- Dependency or permission surface needs review
- Permission surface may require sandboxing
- Financial research output is not financial advice; require human review before any live investment decision
- No explicit error handling or rate limit guidance for API calls.
- The skill does not specify how to parse or interpret the API responses beyond raw data.
- Financial research output is not financial advice; require human review before any live investment decision.
- Quality score needs review
- Permission surface needs review: secrets or environment access, shell or command execution
- Dependency/runtime risk: command execution surface, credential or environment access
- Permission surface: secrets or environment access, shell or command execution
- Verified installs
