seo-link-audit — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited seo-link-audit (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
A link profile is a portfolio. The audit asks four questions: how many distinct authoritative voices vouch for the site, how natural does the anchor distribution look to an algorithm, how much penalty exposure is hiding in the long tail, and where do credible competitors get links that this site doesn't. The answer is a prioritized finding list — not a vanity count of "total backlinks." Raw inbound count has been an inferior signal since 2019; unique referring root domains, topical fit, and authentic-mention sources are what compound in 2026.
The March 2026 core update sharpened this: 80% of top-3 results shifted, intermediary pages were demoted, and algorithmic link-spam detection moved from "months to take effect" to "minutes." Paid-link risk got worse, not better. The audit identifies risk patterns before they become algorithmic suppression.
Three lenses, applied in order:
Audit walks the lenses in order. Authority surface tells you what's working; risk surface tells you what could collapse; gap surface tells you what to chase next.

| # | Check | How to verify | Severity if failed |
|---|---|---|---|
| 1 | Unique referring root domains | Count distinct root domains linking to the site (not URLs, not subdomains) | Note as baseline; flag if <30 for sites older than 12 months in a competitive niche |
| 2 | Topical fit distribution | Sample 20 referring domains; categorize as in-niche / adjacent / off-topic | Critical if >50% off-topic (reasonable-surfer discount); Moderate if >70% adjacent |
| 3 | DR/DA distribution | Sample distribution across DR bands; no single source contributing >30% of total link equity | Moderate if concentration risk (one DR-80 + a long tail of DR-10) |
| 4 | Anchor-text distribution | 40–50% branded, 20–30% partial-match, 15–25% semantic/long-tail, 5–10% generic, <10% exact-match (data-backed: 68% manual-action reduction with diversification) | Critical if exact-match >15%; Moderate if branded <30% |
| 5 | Toxic-neighborhood exposure | Sample referring domains; check for casino/pharma/adult/foreign-language farms or sites that link to those | Critical per identified toxic referrer; recommend disavow only after exhaustion of removal-request path |
| 6 | Paid-link risk patterns | Look for: dofollow links from sites with "sponsored" / "advertorial" navigation, sites in known paid-link networks, niche-edit/link-insertion services | Critical per pattern detected — 2026 algorithmic devaluation is minutes, not months |
| 7 | Velocity profile | Look for unnatural spikes — 50+ links in a week from disparate sources is fine ONCE on a newsworthy basis; sustained spikes trigger SpamBrain | Moderate if recent spike unexplained; Critical if pattern is ongoing |
| 8 | Manufactured-mention signals | Look for bulk-purchased "brand mention" patterns — same wording across many sites, low-quality directories, AI-generated guest-post farm placements | Critical per pattern (Google's 2026 AI optimization guide is explicit: manufactured mentions trigger the same discount as cheap directories) |
| 9 | Link gap vs niche competitors | Identify 3 same-niche same-DR-tier competitors; list referring domains they have and this site doesn't | Document as opportunity, not deficit; rank by topical fit × authority |
| 10 | Community / forum presence | Reddit (especially relevant subreddits), Stack Exchange, niche forums — is the brand mentioned naturally and recently? | Moderate if absent in niches with active communities (Reddit is now ~37% of AI Overview citations from social/forum sources) |
| 11 | Brand search volume signal | Search volume on "<brand>" and "<brand> + [modifier]" — is it growing? Brand search now outweighs backlinks as an LLM citation predictor. | Moderate if brand search trending flat/down while backlink count is growing (suggests inorganic link-building) |
| 12 | Unlinked-mention surface | Sites that mention the brand without linking — reclamation opportunity | Document as opportunity |
| 13 | Site Reputation Abuse exposure | Are any inbound links from "best [X] [year]" listicles on Forbes/CNN/Times brand subdomains? Aug 2025 update made enforcement algorithmic; decay is 6–8 weeks. | Note as time-bounded link, not durable authority |
| 14 | Primary-source pass-through | When links come from intermediary aggregator pages, weigh discounted vs links from primary-source publications (March 2026 update demoted intermediaries) | Moderate if portfolio skews to aggregators |
Targets (from manual-action correlation studies and Google's own guidance through link-spam updates):
Diversification reduces manual-action exposure by ~68%. The exact-match cap is the single most-violated rule in link-building campaigns; over-optimization here is a leading penalty trigger.
Any of these without rel="sponsored" is a Critical finding. The Oct-2025 update made guest-post farm placements (AI-generated content + paid embedded link) a distinct violation category; the March 2026 update made algorithmic devaluation near-instant.
