Write about a topic that interest teenagers. Topics like politics, government, and cooking are probably not the best subjects to write about when trying to interest teenagers. On the other hand, ghost stories, murder mysteries, and sports stories are of interest to most teenagers.
Use small paragraphs. This is necessary to keep the attention of your young audience. Long, drawn out paragraphs will immediately turn them off of the book. Writing in this manner also allows you to use more space with fewer words.
Describe your characters in great detail. Teenage readers will become very interested in your book if they can visualize who they are reading about.
Incorporate popular teen slang. Make certain you understand the context and usage of these terms before you begin using them. A good idea is to speak with teenagers in your area or visit a local junior high school so you can fully understand how teenagers speak and associate with their peers.
Exhibit ethical behavior. If one of your characters breaks the law or misbehaves, make sure they get caught or punished. This will exhibit to the parents that you do not condone this behavior, and to the readers that all bad habits and behavior will eventually be punished.
