Side Hustle: Selling Low-Content Books on Amazon

The "Low-Content Book" side hustle—selling products like journals, notebooks, planners, and logbooks on **Amazon Kindle Direct Publishing ($\text{KDP}$)**—remains one of the most accessible routes to generating **passive income** in $\text{2025}$. The appeal is simple: you create the interior pages once, design a cover, and $\text{Amazon}$ handles the printing, shipping, and customer service every time a book sells.

However, the market is competitive. Success now depends entirely on **niche targeting** and leveraging **AI tools** to scale your output efficiently.

What are Low-Content Books?

Low-content books require minimal creative effort on the interior pages. Their value lies in the **cover design** and the **utility** of the interior structure. Examples include:

• **Journals:** Lined paper, gratitude prompts, or daily planners.
• **Logbooks:** Mileage trackers, blood pressure logs, or fishing records.
• **Planners:** Academic planners, wedding organizers, or fitness trackers.
• **Coloring/Activity Books:** Simple maze or coloring templates (often considered medium-content).

Step 1: Niche Research is Everything

You cannot succeed by selling a generic "Notebook." You must find a sub-niche with demand but low competition. This is where the money is made.

Finding Profitable Niches

Use Amazon search to find phrases with high traffic but few high-quality listings:

• **Example Niches:** "Veterinarian Appointment Planner," "Amateur Radio Call Log Book," or "Vintage Car Restoration Tracker."
• **The $\text{BSR}$ Check:** Use a free browser extension (like DS Amazon Quick View) to check the Best Seller Rank ($\text{BSR}$) of competitors. A $\text{BSR}$ under $\mathbf{100,000}$ indicates the niche is selling well.
• **Price Point:** Focus on books you can list between $\mathbf{\$6.99}$ and $\mathbf{\$9.99}$. This sweet spot provides a reasonable royalty after Amazon’s printing and fee deductions.

Step 2: Leveraging $\text{AI}$ for Design and Scale

In $\text{2025}$, graphic design and interior layout should be outsourced to $\text{AI}$ to maximize your time creating and launching products.

The AI Design Toolkit

• **Cover Art (Midjourney/DALL-E):** Use advanced $\text{AI}$ image generators to create professional, high-resolution cover designs in minutes. Prompt for specific styles (e.g., "Minimalist aesthetic cover for a bird-watching logbook").
• **Interior Layout (Canva/KDP Templates):** Use free $\text{KDP}$ templates for standard interiors (lined, grid). For custom templates, design once in Canva or Affinity Publisher, save it as a $\text{PDF}$, and reuse it across multiple niche titles.
• **Keywords & Titles (ChatGPT/Claude):** Use $\text{AI}$ Large Language Models ($\text{LLMs}$) to brainstorm $\text{7}$ highly relevant, long-tail keywords and optimize your book titles and subtitles for discoverability on $\text{Amazon}$.

Step 3: Uploading and Automation

Amazon $\text{KDP}$ is a Print-on-Demand ($\text{POD}$) service. You do not hold inventory, which is key to the passive nature of this side hustle.

• **Formatting:** Ensure your interior $\text{PDF}$ matches the selected trim size (e.g., $\text{6x9}$ inches) and page count ($\text{100}$ to $\text{120}$ pages is standard).
• **Pricing:** Keep your price competitive with the top $\text{3}$ to $\text{5}$ results in your niche.
• **Scale:** The goal is volume. Aim to launch at least **$\mathbf{1}$ new, highly niched book per week** for the first $\text{6}$ months to build your catalog. Passive income grows exponentially with the size and quality of your listing portfolio.

Selling low-content books is a marathon, not a sprint. Consistency in niche research and leveraging $\text{AI}$ to rapidly prototype and launch products are the keys to building a substantial passive income stream on Amazon $\text{KDP}$.
