How to Promote Your Book Online: A Simple 30-Day Plan for Independent Authors.

Publishing your book is a major accomplishment, but once it is available for sale, another question quickly appears:

How do you get people to discover it?

Book promotion can feel overwhelming because there are so many things authors are told they should be doing—posting on social media, making videos, creating graphics, finding readers, building an email list and promoting without sounding as though they are constantly selling.

You don't have to do everything at once.

A simple 30-day promotion plan can help you turn one book into weeks of useful marketing content.

Start with your reader, not your book

Before creating promotional posts, think about the person most likely to enjoy your book.

Ask yourself:

  • Who is the book for?
  • What would make that reader interested?
  • What problem, emotion, experience or entertainment does the book provide?
  • Where does that reader spend time online?

For a children's picture book, for example, the buyer may actually be a parent, grandparent, teacher or caregiver rather than the child.

Knowing this changes the way you promote the book.

Don't post the same sales message every day

One of the easiest mistakes to make is repeatedly posting:

“My book is available. Buy it here.”

Instead, create different reasons for someone to become interested in the book.

During your 30-day campaign, you might share your book cover, a behind-the-scenes story, information about a character, the inspiration for the book, a reader benefit, a short author video, a question for readers, a review or testimonial, and reminders about where the book can be purchased.

You're still promoting the same book, but you're telling the story from different angles.

Create your promotional graphics in advance

You don't need a brand-new design every day.

Create a small collection of reusable graphics based around your actual book cover and visual identity.

For example, you could prepare graphics for the book introduction, a featured character or theme, a reader benefit, an author message, a quote or short excerpt, a review, a reminder and a direct purchase call-to-action.

Preparing these beforehand makes a month-long campaign much easier to maintain.

Turn your ideas into short videos

Short-form video gives authors another way to introduce their books without requiring elaborate production.

Some videos can be extremely simple: show the book while explaining who it's for, tell viewers why you wrote it, introduce one of the characters, share a behind-the-scenes detail, answer a reader question, or explain what you hope readers take away from the story.

One book can provide many different video ideas.

Write your captions before you need them

Trying to decide what to write every time you open Instagram or Facebook can make book promotion exhausting.

Instead, prepare a collection of captions in advance.

Some can tell stories. Some can ask questions. Others can highlight the book's benefits, introduce characters, provide behind-the-scenes information or invite readers to learn more.

You can then adapt those captions for the platform you're using instead of starting from a blank page every day.

Spread the work across 30 days

Your promotion doesn't need to mean posting everywhere every day.

Think of the month as a campaign.

During the first week, introduce the book and its story. During the second, help readers understand who the book is for and why they might enjoy it. During the third, use stories, videos and different promotional angles to deepen interest. During the final week, reinforce the strongest messages and give readers clear opportunities to purchase or learn more.

Consistency is more useful than trying to create everything at once and becoming overwhelmed.

Your book already gives you something to talk about

Book marketing becomes much easier when you stop thinking that you need a new idea every day.

Your book contains the characters, themes, reader benefits, story, inspiration and visual material that can fuel your promotion.

The goal isn't simply to post more.

It's to create a manageable system that helps the right readers repeatedly discover your book.
