Toxic Link
A backlink from a spam site, link farm, or unrelated adult or gambling property that can drag down the ranking of whatever it points at.
Analogy Mental model
Being seen with the wrong crowd. A teacher who spots you alongside the class troublemakers starts wondering about you as well.
In practice What you actually do
Run a periodic audit and triage by pattern rather than by score alone: near-zero authority combined with topical mismatch, repetitive exact-match anchors, or a known farm footprint. Write down each decision and its reasoning so a later reviewer can follow your logic.
Where people get burned Pitfalls
Mass disavowing everything under an arbitrary threshold does more harm than good, because search engines already ignore most junk automatically. Reach for the disavow file when you have a manual action or clear evidence of a negative campaign.
