There is no standard definition of “predatory journal,” a term first used by librarian Jeffrey Beal to describe what he called “counterfeit journals.”
"Predatory journals and publishers are entities that prioritize self-interest at the expense of scholarship and are characterized by false or misleading information, deviation from best editorial and publications practices, a lack of transparency, and/or the use of aggressive and indiscriminate solicitation practices."

Predatory publishers take advantage of the open-access publishing model for financial gain. These publishers actively seek out faculty and researchers, targeting those who need to publish their work to fulfill promotion, tenure, or funding requirements. Their goal is to exploit these authors by charging them while failing to provide the peer-review process for their publications.
What happens when you publish in a predatory journal?
If you find out that you’ve submitted your work to a predatory journal, consider retracting your paper and seeking institutional support.

Committee on Publication Ethics (COPE) - a cross-industry initiative that aims to “move the culture of publishing towards one where ethical practices become the norm, part of the publishing culture.” The organization recently consolidated its code of conduct and best practice guidelines for editors and code of conduct for journal publishers into a single, 10-point “core practices” document. It includes cases with advice, guidance for day-to-day practice, education modules and events on topical issues, to support journals and publishers fulfill their policies.
