Hello,
I always use search engines to find the best journal for my papers. They are so good because they provide lots of information about potential journals, such as their indices, impact factors, acceptance rates, review and publication speed etc. I know a couple of journal search engines. The journal search engines I know and use are as follows:
Thomson Reuters: http://myendnoteweb.com/ (Endnote Web Match)
Elsevier Journal Finder: https://journalfinder.elsevier.com/
Springer Journal Suggester: https://journalsuggester.springer.com/
American Journal Experts Journal Guide: https://www.journalguide.com/
I wonder if you know and use any others that could be of additional help. Thanks.
