Predatory publishing has become harder to spot, not easier. The obvious offenders, with broken English and implausible promises, still exist, but the more difficult cases are journals that look entirely ordinary and fail on one or two specific points.
The reliable approach is not a feeling about a journal’s website. It is a short list of checks that can be verified independently, in about ten minutes.
The checklist
1. Verify indexing at the index, not the journal
The most common false claim, and the easiest to check. If a journal says it is indexed in Scopus, Web of Science, PubMed or DOAJ, search that index directly for the journal title. Do not follow a link from the journal’s own site, and treat logos on the journal’s page as decoration, because that is often exactly what they are.
Note also the difference between being indexed and being “submitted for evaluation”, which is a phrase doing a great deal of work.
2. Verify the editorial board
Pick three board members at random and check their institutional pages. You are looking for two things: that they exist and work where they are said to, and that the journal appears somewhere in their own listed activities. Researchers are regularly listed on editorial boards without their knowledge, and a board of real people is not by itself evidence of anything.
3. Check APC transparency
A legitimate journal states its charge clearly, before submission, in a place you can find without searching. A charge that appears only after acceptance is the single most reliable warning sign in the whole list, because it converts an editorial decision into a financial one.
4. Check the review-time promise
Genuine peer review takes weeks. A promise of review in 72 hours, or publication in two weeks, describes a process that cannot include finding, briefing and waiting for qualified reviewers. Fast is possible. That fast is not.
5. Check the scope
Journals with implausibly broad scope, covering engineering, medicine and the humanities in one title, are not serving a research community. Legitimate multidisciplinary journals exist, and they describe their remit with precision rather than by listing everything.
6. Read three published articles
The most direct test available, and the one most often skipped. Are they competent? Are they proofread? Do the figures meet ordinary standards? A journal cannot fake its own back catalogue.
7. Check contact details and location
A verifiable postal address, an institutional or domain email rather than a free webmail account, and a named editor you can contact. Vagueness about where the publisher actually is remains a strong signal.
8. Check for the unsolicited invitation
Legitimate journals occasionally solicit submissions. They do not send flattering email about a paper of yours they have clearly not read, addressed to the wrong field, with a discount for submitting this month.
No single check is decisive on its own. Two or more failures, particularly unverifiable indexing combined with an undisclosed APC, is enough to walk away.
Useful tools, with a caveat
The Directory of Open Access Journals applies real inclusion criteria and is a good positive signal. Think. Check. Submit. offers a structured checklist. Your librarian is frequently the fastest route to an informed answer.
Be more careful with blocklists. They are maintained inconsistently, they go out of date, and they contain both false positives and gaps. Use them as a prompt to check further, never as a verdict.
If you have already submitted
Withdraw in writing before acceptance if you can, and keep the correspondence. Once an article is published, most such journals will not remove it, and you cannot submit the same work elsewhere while it stands. Withdrawal fees are sometimes demanded; they are usually not enforceable, but the situation is far easier to avoid than to resolve.
