Moz / BuzzSumo 2015 study (>1M articles; random 100K sample) — over 75% had zero external links ("3 in 4 posts got zero referring domain links")
Summary
Claim: The 2015 Moz / BuzzSumo study of over 1 million articles found that, in a randomly selected sample of 100,000, "over 75% had zero external links" (BuzzSumo's own phrasing: "3 in 4 posts got zero referring domain links") — the empirical backbone for why a purpose-built linkable asset (a tool) beats an ordinary page.
Source: Moz / BuzzSumo 2015 study.
Confidence: Industry-consensus — Moz/BuzzSumo both sell SEO tools, but the finding is widely cited and methodologically transparent.
Why this matters for Candid: Strongest single empirical justification for the linkable-asset thesis. Most content earns zero external links — purpose-building for citability is the exception, not the default. Anchors R4 — When SEO is part of the case, build for CITATION not just utility — the public quotable number earns the links; the private personal answer does not.
