You should ask "Is there an easy way to publish paper in prestigious journals?" To me, you can only facilitate your journey by working hard on your paper, then receiving feedback from the experts in your field; after that, keep searching for journals relevant to your study to submit your paper.
The best way to publish an article in an indexed journal is to see to it that your paper is original, well written and edited, and then you can send it to a journal that covers research similar to yours. It is important that the journal you choose will be within the aims and scope of your paper.
First, choose your domain of research. Then, browse the journals on the desired domain and read previous articles in the selected domain. Finally, start your research and writing the paper. Before, submitting the paper to a journal, consult experts in the field.
The phrase Easy Way sounds like "How can I bypass the standard protocol to publish in indexed journals?" Please do not look for an easy way. One needs to invest huge amount of human labor to do a rigorous research work to publish in a prestigious journal. This will give you an inner satisfaction and joy at the end. You will cherish the fruit of your labor.
