Knowing your target audience is the process of understanding which section of people loves your work more than the rest of them. This is a great way to determine your loyalists and to aim at the content that your readers will be most interested in. A lot of this knowledge comes once you ascertain a genre for your writing. Additionally, demographics like gender, age, orientation, education, socio-political factors, life experiences, etc contribute largely to narrowing down your target readers. Crafting your work keeping the interest of your readers as a priority will aid in developing marketing campaigns to derive the most from that same audience.
