It’s important to keep in mind where you plan to publish your journal paper, as this clearly defines your audience.
For example, if your paper is to be published in a general interest journal, you should keep the focus broad. If it is aimed at a highly specialist journal, you probably don’t need to define familiar terms and concepts that your audience will already know.
It is not always easy to ensure all required information is organised and structured well in your journal paper introduction. Obviously, you can’t include everything in your Introduction. Which kind of leads us to our next question:
As a rough guide, an introduction should be around 20% of the word count of the entire journal paper. However, the length will also depend on your specific field and the word limit of the journal to which you are planning to submit.
So, always check the journal guidelines and also the length of the Introduction sections in similar journal papers for reference.
Without the context and direction of an Introduction, your audience will be lost and confused – so be sure to give them the roadmap that they need.
