How to Spot a Predatory Journal Before You Submit

Predatory journals charge authors fees but do little or no real peer review or editing. Publishing in one can damage your reputation, waste your work, and in some cases make the paper hard to publish elsewhere. Emails from them are constant, and some are convincing. Here is how to check a journal properly before you submit.

There is no perfect list, and the line between low quality and predatory is not always sharp. So the goal is not to memorise a blacklist. It is to build the habit of checking a journal yourself.

Warning signs

• They contacted you. An unsolicited invitation to submit, especially one with flattering language, is a red flag. Legitimate journals do sometimes invite papers, but a pattern of generic emails is not a good sign.
• A very fast review, such as acceptance within days, or a promise of one. Real peer review takes weeks or months.
• A scope that covers everything, or a journal name that closely imitates a well-known one.
• Vague or hidden fees. Legitimate open-access journals state their article processing charges (APCs) clearly on their website before you submit. Being surprised by a fee after acceptance is a red flag.
• A missing or fake editorial board: no named editors, editors with no verifiable affiliation, or people who say they never agreed to serve.
• Poor English or design on the site itself, broken links, or a contact address that is only a free email account.
• Misleading metrics, such as an invented “impact factor” from a company you have never heard of, or claims of indexing that you cannot verify.

Checks you can run in ten minutes

1. Look at the papers. Read two or three recent articles. Is the quality reasonable? Does anyone in your field cite this journal? Are there obvious errors that a reviewer would have caught?
2. Check the editorial board. Search for two or three editors independently and confirm they exist, are in your area, and actually work where they say.
3. Verify indexing at the source. If the journal claims to be in Scopus, Web of Science, or PubMed, look it up on those databases' own sites, not on the journal's page. Note that being indexed today is not a guarantee, since indexes do remove journals.
4. Check open-access directories. For open-access journals, the Directory of Open Access Journals (DOAJ) applies criteria to the journals it lists, so a DOAJ listing is a useful positive signal.
5. Look for membership of publishing-ethics bodies, such as the Committee on Publication Ethics (COPE), and confirm it on that body's own member list.
6. Read the peer-review policy and the fee page. They should be specific: what type of review, how long it takes, and what it costs.
7. Ask your supervisor or librarian. Your university library almost certainly has a process for exactly this question.

A note on hijacked and clone journals

Some fake journals copy the name and website of a real one to collect fees. If a journal's website looks right but the email or submission link looks odd, go to the publisher's own site through a search engine, or through the link on a trusted database, and check that the details match.

If you have already submitted

If you realise a journal is not legitimate after you submit, you can usually withdraw the manuscript in writing before publication. Keep a copy of the email. If it has already been published, talk to your supervisor and your library. Do not pay for a retraction you do not need, and be wary of any demand for extra fees.

Choosing well in the first place

The best protection is a shortlist built before you write: journals your supervisor and colleagues cite, that are indexed where your field expects, and whose scope, review time, and fees suit your paper. Shortlisting early also saves you from panic-submitting to the first journal that says yes.
