Smart Spending: Maximizing Your Marketing Budget

Series: THE INDIE AUTHOR’S JOURNEY: A Real-World Guide to Self-Publishing


Part 4: Marketing & Promotion

May 7, 2025 | 9-minute read

Last week, we explored general marketing strategies to promote your books. Now it’s time to focus specifically on advertising — the paid promotion that can dramatically increase your book’s visibility when done right.

For many authors, advertising feels intimidating. The platforms are complex, the learning curves steep, and the potential to waste money is very real. But effective advertising doesn’t require a marketing degree or a massive budget — just a strategic approach and willingness to learn through testing.

In this post, I’ll break down the major advertising platforms available to indie authors, share tips for creating effective ads, and offer guidance on budgeting that won’t break the bank.

Whether you have $10 or $1000 to invest in advertising, you’ll learn how to make those dollars work harder for your books.

Let’s dive into the world of book advertising and discover how to connect your stories with readers who are actively looking for their next great read!

Amazon Advertising: The Retail Giant’s Playground

Amazon ads have become essential for most indie authors, particularly those publishing through KDP.

Let’s break down the key components:

Types of Amazon Ads

  • Sponsored Products: Your book appears in search results and on similar book pages

  • Lockscreen Ads: Featured on Kindle device lockscreens (invitation only)

  • Product Display Ads: Appear on specific product pages

Getting Started

Creating your first Amazon ad campaign is straightforward:

  • Access the KDP dashboard and select “Marketing”
  • Choose your ad type and target book
  • Set your daily budget (start small — $5-10/day)*
  • Select targeting method (keywords or product targeting)
  • Create your ad copy

* The general belief and practice that I’ve found online is to start with a small budget. Though I agree on a small budget (and my pocketbook’s thankful!), as you’ll see below in “Personal Journey,” I’m doing my own investigation into the right budget amount. I’ll post my findings and what worked best for me in a future post. (Hint: You may be able to get away with less than $5 a day!)

Targeting Strategies

For best results:

  • Research genre-specific keywords
  • Target relevant author names
  • Include book titles similar to yours
  • Test both automatic and manual targeting
  • Start broad, then refine based on performance

Measuring Success

Focus on these key metrics:

  • Impressions (how often your ad is seen)

  • Clicks (how many people clicked your ad)

  • Click-through rate (CTR)

  • Conversion rate (sales from clicks)

  • ACOS (Advertising Cost of Sale)

Amazon advertising works best when you view it as an ongoing experiment. Start with small budgets, test different approaches, and gradually scale what works.

Personal Journey

I’m currently reading an eBook about how to work Amazon ads as an indie author so that you don’t break your bank. Don’t know about you, but money is tight, and I don’t want to spend more than is necessary.

So far, this book is giving me hope that I can work Amazon ads cost-effectively.

When I finish and have put into practice what I’ve learned, I’ll write a review on the book and on how the author’s advice worked for me. So, keep checking back. (Or better yet, subscribe to my weekly newsletter so you never miss all my news and reviews! The link’s below.)

Facebook Advertising: Precise Audience Targeting

While I’m still navigating the Amazon advertising landscape, Facebook offers a completely different approach to reaching potential readers.

Instead of targeting people actively shopping for books, Facebook allows you to find readers based on who they are and what they like — aka, demographics, interests, and behaviors.

This platform has its own learning curve, but its precise targeting capabilities make it worth exploring as part of your advertising mix.

Campaign Structure

Facebook ads consist of:

  • Campaigns (overall objective)

  • Ad Sets (audience and placement)

  • Ads (creative content)

Audience Targeting

Facebook’s strength is its targeting capabilities:

  • Core demographics (age, location, gender)
  • Detailed interests (book genres, authors, topics)
  • Behaviors (book buyers, e-reader owners)
  • Custom audiences (your website visitors, email list)
  • Lookalike audiences (people similar to your readers)

Designing Compelling Ads

Your Facebook ad should include:

  • Eye-catching image (your cover or themed graphic)
  • Compelling headline
  • Brief, engaging copy
  • Clear call to action
  • Link to purchase page

Budget and Bidding

Start small and scale gradually:

  • Test with $5-10/day
  • Use campaign budget optimization
  • Monitor cost per click (CPC)
  • Evaluate ROI regularly

Remember that Facebook ads typically require more testing than Amazon ads. The platform is less about immediate sales and more about building awareness and nurturing potential readers.

BookBub: Reaching Dedicated Readers

If you haven’t heard of BookBub yet, you’re missing out on one of the most powerful promotional tools in the indie publishing world!

BookBub is a free service that notifies millions of readers about limited-time discounted eBooks that match their interests.

What makes BookBub special is its highly engaged audience — these aren’t casual browsers but dedicated book lovers actively looking for their next read.

The platform has carefully curated a trusted relationship with readers, which means promotions through BookBub typically see much higher conversion rates than other advertising channels.

For authors, BookBub offers two main advertising opportunities with very different approaches:

Featured Deals

The gold standard of book promotion:

  • Massive exposure to targeted readers
  • Typically generates thousands of downloads
  • Highly competitive application process
  • Requires significant price discount
  • One-time fee based on genre and price

While Featured Deals offer tremendous ROI, they’re difficult to secure and require planning your pricing strategy in advance.

BookBub Ads

Self-service advertising platform:

  • Target by author or category
  • Set your own budget and schedule
  • Design your own custom graphics
  • Auction-based pricing
  • Immediate access (no application)

BookBub Ads typically have higher costs but can deliver better quality clicks than other platforms since you’re reaching dedicated readers.

Budget Considerations: Making Every Dollar Count

After exploring the major advertising platforms, the question on most indie authors’ minds is: “How much should I actually be spending?”

It’s the question that keeps us up at night, especially when our publishing budgets are already stretched thin from covers, editing, and formatting.

While there’s no one-size-fits-all answer, there are some general guidelines that can help you approach advertising spending strategically.

And let me stress again that I’m still conducting my own inquiries into the best budget for Amazon ads. So take the following advice as “best marketing practices” of the current consensus.

Starting Budget Guidelines

  • New authors: $50-100/month
  • Established authors: $200-500/month per book
  • Series authors: Focus on first-in-series

Maximizing ROI

  • Test small before scaling up

  • Track all results meticulously

  • Be willing to pause underperforming ads

  • Reinvest profits from successful campaigns

  • Consider the customer lifetime value

When to Increase Spending

The best times to increase ad spend:

  • During a new release
  • When you have a BookBub Featured Deal
  • When you have a proven high-converting ad
  • During seasonal peaks for your genre

Creating a Sustainable Advertising Strategy

The most effective advertising approach combines:

  • Continuous low-level baseline advertising
  • Strategic promotional pushes
  • Periodic testing of new platforms and approaches

Remember that advertising is one component of your overall marketing strategy. It works best when supported by a strong author platform, quality books, and authentic reader engagement.
