Most academic journals have strict plagiarism policies to ensure the originality and integrity of published research. Generally, journals set a maximum similarity threshold of 20%, meaning that if a submitted manuscript has more than 20% similarity to existing works (excluding references and common phrases), it may be flagged for plagiarism concerns.

To comply with this policy, authors must ensure that their work is original and properly cited when referencing previous studies. Direct quotations should be clearly marked, and paraphrased content must be rewritten in the author's own words while still acknowledging the source. Smart Techno use Turnitin as plagiarism detection tools to check similarity scores before peer review. If a paper exceeds the 20% similarity threshold, authors may be required to revise and resubmit or risk rejection due to potential ethical violations.
