-try to publish under reputed publishers

-consider multiple indexing (Scopus+Esci or Esci+ABDC etc.)

-avoid paid journals

-select journals with less issues per year

Dear P. Contreras thank you sir for your reply. But publishing in predatory journals sometimes considered as a discredit in scholar community.

Dear Wolfgang R. Dick thank you for the links.

Dear Ariful Islam thank you sir for your reply. I like your suggestions. However, with less issues, don't you think that it takes more time to get published?

First and foremost, look at the quality of the review process and the general quality of the articles published there. You will realize that most predatory journals either don't review articles at all or do it shallowly. Reviewers are difficult to get especially for technical papers. As such, a review of a technical paper within 2 or 3 days should be a pointer to predatory journals.

Dear Vincent O. Nyangaresi thank you so much for your reply sir. However, what to do if a paper gets published in a predatory journal accidently?

Dear Dr Mohammad Razib Hossain

Just check the journal if it is predatory or not then select the best suitable one for you .

Mohammad Razib Hossain All good journals take time to publish. Faster publication is an alarming sign.

Dear Aref Wazwaz thank you sir for your reply. Can you please suggest me any website where I can check for predatory journals?

Dear Ariful Islam thank you again for your reply. What about the journals under MDPI, they also publish very fast.

Mohammad Razib Hossain . Yes . See the following useful link: https://beallslist.net/how-to-recognize-predatory-journals/

Good and quality journals do not publish articles on time because of the numbers of articles they receive and their selection process. Once a journal is good, it creates selection headache for reviewers.

Dear Aref Wazwaz Thank you for your support sir.

You are most welcome dear Mohammad Razib Hossain

Wish you the best always

Dear Ineke Ugbede Joseph thank you for your reply. But how can you avoid the predatory traps? And what to do if you fall in their traps accidently?

If they ask you for money, avoid it.

The rest comes by itself.

The biggest annoyance happens when they "bump into" you, as happened to me recently:

https://www.researchgate.net/post/Continuous_invitations_to_publish_who_received_them

Dear Gioacchino de Candia thank you sir for your reply.

Mohammad Razib Hossain The reputation of MDPI is highly questionable. MDPI was once listed by Jeffrey Beall as potential predatory publisher.

Dear P. Contreras Thank you sir for your suggestions

Dear Ariful Islam thank you so much. I do agree with you. Sometimes they publish within a month or less.

Thank you @Mohammad Razzib Hossain. Researchers who do not engage in panic publication hardly fall into the traps of predatory journals. It is important for researchers to see publishing as a service to the knowledge industry than an ingredient for promotion. Since the numbers of articles published by researchers are part of the requirements for promotion, most researchers who are not active, always rush into pushing their articles to any available publishing outlets at the eve of their promotion. The foregoing, explains why predatory journals are still getting subscriptions.

Well, the world predatory journal varies for people, countries, universities, etc. For example, one journal is considered very good in a country but is black listed by another.

Check the journal name and ISSN in Web of Science, Scopus, impact factor list, or any other indexing recognized by your country or higher education to avoid predatory journals.

Regarding money, it's not necessary if a journal has APC, it will accept papers for the exchange of money. Nature is one of the best publishing agencies but their fees are the highest for most of the journals. Yes, it is true that paid journals take money to speed up the review process. There are some journals that are doing business but this doesn't mean all paid journals are the same.

Anyone can disagree. Thanks

Dear Ineke Ugbede Joseph

Thanks again for your insightful reply.

Dear Ihtisham M.

Thanks for your reply sir.

I do agree with your thoughts. However, the malpractice of publishing worthless articles should be banned so that nobody becomes a victim of this fraud.

Make false claims about where the journal is indexed (e.g. PUBMED). Promise fast publication. Promise an easy peer-review and process. Have titles very close to those of highly respected legitimate journals, with only subtle modifications.

Dear Haseeb Javed vai,

Thanks for your suggestions. Sometimes they even claim that they are indexed in Scopus

By ignoring the numerous flattery invitations from them. Examine the journal carefully and check the indexing well.

Dear Emmanuel Kobina Mesi Edzie

Thanks for your reply. Can the scholarly community (researchers and academicians) play any role in taking step against predatory journals?

Before you submit your article there are steps you can take to ensure you select a high-quality journal and avoid predatory publishers: Check to see if the journal is indexed in MEDLINE/PubMed (use filter "currently indexed in MEDLINE") or another reputable literature database such as Web of Science, CINAHL, etc Mohammad Razib Hossain

Dear Shivam Maurya

Thank you for your suggestions. Will try to follow these.

Agree with Dr. Ihtisham.

Check them on website of master journal list i.e. https://mjl.clarivate.com/home

Dear Sanaullah Ansari thanks for the recommendation.

Consult your supervisor and university guidelines in your institution.

Dear Kiprotich Kiptum thank you for the suggestion.

Ensure that the journal has a reputable contact address.

It's simple. Consistent researchers and published authors should be aware of Bell's Predatory Journal database, which keeps them safe from making the wrong choices on where to publish.

Please use this link below which is updated from time to time to stay out of trouble.

https://beallslist.net/

It will do you a lot of good and save you from unwarranted heartaches. Going through the list won't be funny especially if you have been publishing without recourse to this database.

Good luck

Meanwhile to choose the right professional journals, use scopus database, which gives you relevant journals with their cite scores, use web of science database, which gives you the Thomson Reuters SCI(E), ESCI, etc ranks and their respective impact factors (IF) for journals rated above ESCI, use SCImago ranking database to know the listed journals' quartile (Q1, Q2, Q3 and so on).

Through simple Google search, you can/will be directed to the appropriate webpages of these academic repository databases.

I wish you well in your search and research activities
