2. Choose a Content Theme and Stick To It
What do you write about? Fitness? Food? Flamenco? Great, you have a target audience, so now you need to choose a consistent theme for your content on Instagram.
First of all, name your account something that will attract them, and then post pictures on your subject.
What if you write fiction? Then consider what genre it is. Whether it is mystery, romance, thriller or YA, it will appeal to certain people and needs an appropriate theme. Even if you write in a mixture of styles and genres, you can always focus on one particular content theme, but there is one type of person who will be interested in them all - bookaholics. These story-junkies are often writers too, so you can also choose to gear your theme towards this group.
Extra Tip: Support their work and they will support yours.
Once you’ve decided on a content theme, stick to it. For example, if you're writing a historical fiction novel, and you have decided to post interesting facts from that period, then make sure you do just that. Those who like your content are going to be more engaged if you keep providing more of the same type of content.
Of course, you can also post other things for variety, such as pictures of you writing in different places (coffee shops are always a winner), or doing research. However, never forget that people who follow you are doing so because they like your content. If you suddenly start posting nothing but pictures of Larry the Labradoodle, when you promised tasty food, then you are likely going to start losing a lot of followers no matter how cute Larry is. True, you might also gain some dog lovers. But they will not be very interested in your writing.
Extra Tip: A note of caution - if every one of your Instagram posts is an appeal for people to buy your book, then they will eventually get bored. Your aim is not just to tell people you have written one, but instead you need to show them why they will love it. So post good photos with interesting captions. If you bore people on social media why would they not expect to be bored when reading your longer pieces?
