External backlink profile from relevant domains
Why it matters
Domains with zero or irrelevant backlinks rank below competitors on every commercial keyword regardless of on-page optimization — Google's algorithm treats link signals as a primary authority indicator, and a thin profile caps how high any page can climb. Sudden spikes from link farms trigger Penguin-style algorithmic demotion, and without a disavow file documenting known-bad sources, cleanup takes months of manual outreach.
Severity rationale
Info because backlink quality influences authority rankings but sits outside codebase-detectable failures.
Remediation
Maintain a disavow list tracked in version control at src/config/disavow-domains.txt and submit it through Search Console's Disavow Tool after each audit:
# src/config/disavow-domains.txt
domain:spam-farm-1.com
domain:link-directory-spam.net
Build earned links through genuinely referenceable content — original research, tools, and data — rather than reciprocal-link schemes.
