Read the magazine you want to write for. Each pop culture magazine has its own style and its own tone. While some are upbeat, others may be more sardonic. Make sure that your tone and style is a good match for the magazine.
Study the topics the magazine wants to cover. Look at the interviews that it does and the editorials. Understanding the content produced by the pop culture magazine helps you create content that interests them.
Write on up-to-date and time-sensitive topics. Pop culture magazines need to content that reflects the present time, and writing about time-sensitive topics helps you attract attention.
Shop your work around. Just because one pop culture magazine does not want your article does not mean that another one will also refuse it. Look for pop culture magazines that have an online presence. Look for a submissions page, which shows you how to submit your work and to whom to address it. While some magazines want to see complete pitches, others ask for a proposal or a synopsis of a written piece.
Choose to write articles that pertain to your own interests or find a way to be interested in the articles that you write. Having a passion for your topic comes through in the text and it helps create a picture for the reader.
