Unique content
Unique content does not merely avoid word-for-word duplication: it delivers substance that cannot be found elsewhere. Formal originality without substantive originality fools no modern ranking system.
In practice
Paraphrasing ten sources produces a technically original and entirely dispensable text. The uniqueness that matters comes from direct experience: your figures, your cases, your measurements. It is slower to produce — and that is precisely why it offers protection: what costs effort to make also costs effort to replicate.
