How to spot a predatory journal — a checklist for researchers
A predatory journal charges authors a fee to publish but skips the real editorial work: no proper peer review, no careful editing and often no long-term archiving. Publishing there can harm your reputation and waste good research. Early-career researchers are the most common targets.
12 warning signs
- An unexpected email invites you to submit, full of flattery ("Dear Esteemed Professor") — often about a topic you do not work on.
- Very fast acceptance promised, such as "peer review in 72 hours".
- The fee is hidden or only mentioned after your paper is accepted.
- A very broad scope, such as "International Journal of Science, Engineering and Medicine".
- A name that copies a famous journal with one word changed.
- The editorial board is fake or unclear — names without institutions, people who say they never joined, or no board listed at all.
- Fake or misleading metrics, such as an "impact factor" from an unknown organisation instead of Journal Citation Reports.
- Claims of indexing that are not true. Check yourself whether the journal is really listed in the databases it names.
- No clear peer-review process described on the website.
- Poor website quality: spelling mistakes, broken links, stock photos, or an address that does not match the country it claims.
- No retraction or correction policy, and no information about archiving (for example with CLOCKSS or Portico).
- Published papers look weak: many grammar errors, unrelated topics side by side, or obvious mistakes that review would catch.
One sign alone does not prove a journal is predatory, but several together are a strong warning.
How to check a journal
- Think. Check. Submit. — the free checklist at thinkchecksubmit.org walks you through the key questions.
- DOAJ: quality open-access journals are listed in the Directory of Open Access Journals. Being missing is not proof of a problem, but being listed is a good sign.
- Check the indexing claims directly on the database websites rather than trusting the journal's logo images.
- Ask a senior colleague or your librarian — they see these journals often.
- Read a few recent papers in the journal. Would you be proud to have your work next to them?
What to do if you already submitted
If you realise the journal is suspicious before publication, write to withdraw your paper in writing and keep a copy of the email. Do not pay any fee you were not clearly told about in advance. Ask your institution's library or research office for help.
