Look for the scope of the journal and also check the standard of your manuscript with the published papers in the chosen journal. Submit the manuscript strictly according to the format of the journal.
I suggest you ask senior reseachers at your educational institutions who have previously published in well known journals to recommend the best ones for you that are relevant to your specialization.
I agree with the above said that you should choose a journal in the scope of your research, this is important for not being rejected immediately by the editor. But also, think about collaborating with a senior researcher who is already experienced with publishing in scientific journals. He can advise you about which journal you should choose and how to improve your paper.Collaborative papers receive more citations than those written by a single author.
