Link Integrity
Accuracy
Every link goes where it says it goes. This agent checks every hyperlink and bare URL in your content — where it points, whether it still resolves, and whether the destination is what the text claims.
What it catches
Links whose visible text spells out one domain but lead somewhere else, dead destinations — both outright 404s and pages that return “200 OK” while showing an error, citations that credit a named source but point somewhere that isn’t it, working links that have nothing to do with what they’re cited for, and domains that outlived their content and now serve a parked page or an ad farm. Sign-in-walled documents get a low-risk nudge to confirm your readers can open them. Sites that block automated readers are reported as unverified, never as broken — a paywalled article is a perfectly good link for a human.
Why it matters
Links are the part of a document nobody re-reads. They rot silently after publish, they carry the citations your credibility rests on, and a single mispaste can send readers to a competitor — or to a lapsed domain serving something worse.
