The practical takeaway

A fixed percentage of copied words is not a reliable publishing rule.

There is no acceptable copying percentage

A fixed percentage of copied words is not a reliable publishing rule. Plagiarism concerns presenting someone else's work as your own, while copyright concerns legal rights in protected material. They overlap but are different issues. A citation does not automatically grant permission to republish an article or image. Similarity checkers can help locate overlap, but they cannot settle ownership, licensing, or whether your use is permitted.

Create value from your own work

Use sources to understand a subject, then explain it in your own structure with original examples. Identify the source of factual research, quote sparingly when necessary, and use images you created or are licensed to publish. Keep records of licenses and permissions. If you find copied material on your site, review it, replace it with original work where appropriate, and seek qualified guidance when a rights dispute requires it.

A checklist you can use

  • Record sources and image licenses.
  • Separate quotations from your own prose.
  • Avoid treating a similarity score as permission.
  • Review contributor submissions before publishing.
