Text uniqueness

• What uniqueness is

  Share of text not matching indexed sources. SEO norm: 90%+ on major services.

• Tools

  Text.ru, Content-Watch, eTXT Antiplagiat, Advego — different algorithms; cross-check at least two.

• Technical vs semantic

  Word swapping gives technical uniqueness, but Google reads meaning. Value = new information, experience, data.

• Cannibalization

  Internal duplicates hurt just as much: canonical, page merging, unique meta tags.

Don't chase 100%: industry terms and laws can't be paraphrased without losing accuracy. Semantic novelty matters more — own data, cases, conclusions. Boilerplate phrases dilute uniqueness at the meaning level.
