Warning signs
What is a red flag for a predatory journal?
A red flag is a sign that should make you pause and verify. A single issue may be explainable; several issues together can show a risky publishing pattern.

Ten red flags to check
- Acceptance is promised before peer review can reasonably occur.
- The journal sends repeated, flattering emails unrelated to your field.
- The publisher hides fees until after acceptance.
- The editorial board cannot be verified or contains names without permission.
- The journal claims Scopus, PubMed, SCI, or impact factor without official evidence.
- The journal title closely imitates a trusted journal.
- The website lists fake metrics or vague “global impact factor” badges.
- Contact details are incomplete, generic, or inconsistent across pages.
- Withdrawal policies include unclear or punitive fees.
- Published articles show little evidence of editing, scope control, or retraction/correction policy.
How to document red flags
Save the email invitation, journal homepage, fee page, editorial board page, indexing claim, and screenshot of the official database search. This protects you if a supervisor, co-author, funder, or institution asks why you rejected the journal.
People also ask
Is fast publication always predatory?
No, but acceptance within days for a full research article is a serious reason to verify the review process.
Are fake metrics common?
Questionable journals often use metric names that look official but are not Journal Citation Reports metrics.
What if only one red flag appears?
Pause and verify. One red flag is not a final judgment, but it should trigger a closer check.
