KDP Low Content Books: Passive Income Blueprint

Okay so here’s the thing about low content books on KDP – most people overthink it and then wonder why they’re not making money. I tested like 30 different niches last quarter and honestly the winners surprised me.

Start With What Actually Sells Not What You Think Is Cool

You gotta look at what’s already working. I use this method where I check the Amazon bestseller ranks in the low content categories – notebooks, journals, planners. Anything under 100k BSR is moving units. Under 50k? That’s your sweet spot. I spent three hours doing this last Tuesday while watching that new detective show on Netflix and found five niches I hadn’t even considered.

The mistake everyone makes is thinking “oh I’ll make a gratitude journal” because they heard it somewhere. But there’s like 50,000 gratitude journals already. You need specificity. Dog training journals. Gratitude journals for nurses. Gratitude journals for people dealing with anxiety. See the difference?

The Research Process I Actually Use

I open like 20 tabs. Just start searching random stuff on Amazon – “log book” “tracker” “planner for” and see what autocomplete suggests. Amazon’s autocomplete is literally telling you what people search for. Write all that down.

Then I check the top 10 results for each search term and look at:

• How many reviews they have
• What the BSR is
• What the price point is
• What the covers look like (are they all similar or is there variety)

If the top books have under 50 reviews but good BSR that means the niche is newer or people buy without reviewing much. Both are fine honestly.

Interior Design Is Where People Mess Up

So you found a niche. Great. Now you need interiors. You can design them yourself in Word or Google Docs if you’re starting with zero budget. I did that for my first 20 books back in like 2018. Took forever but it’s doable.

These days I use Canva Pro or sometimes Book Bolt. Book Bolt costs money but it’s worth it if you’re serious – the interior templates alone save you hours. I probably save 3-4 hours per book using their stuff.

Page Count Matters More Than You Think

Here’s what I learned the hard way – Amazon’s royalty structure means you make more profit on books between 100-120 pages than you do on 200+ page books in most cases. Because printing costs go up but you can’t always raise the price proportionally.

My sweet spot is 110 pages for most journals. That lets me price around $6.99-$8.99 and still make $2-3 per sale. Which doesn’t sound like much until you’re selling 10-15 copies a day across multiple books.

Oh and another thing – bleed matters. If your interior has borders or designs that go to the edge you need to set up bleed properly or Amazon will reject it. I still sometimes forget this and have to reupload. Make your interior with 0.125″ bleed on all sides if you’re going to the edge, or just keep everything at least 0.25″ from the edges and you’re fine.

Cover Design Is Actually Easier Than People Say

Use Canva. Seriously. Their KDP cover templates are already sized right. You just need to make something that:

• Clearly shows what the book is
• Looks professional enough (not necessarily fancy, just clean)
• Stands out in thumbnail size

I test my covers by shrinking them down to like 1 inch tall on my screen. Can you still read the title? Does it catch your eye? Cool, it’ll probably work.

The biggest mistake is making covers too busy. I see people adding like 8 different fonts and 20 graphics. Keep it simple. Title, subtitle if needed, maybe one graphic element. Done.

Colors That Actually Convert

This is gonna sound weird but I track this stuff in a spreadsheet. Certain color combinations just perform better for me. Teal and gold. Navy and white. Burgundy and cream. These consistently get better click-through rates than like… neon colors or all black covers.

Feminine niches (planners for moms, wedding planners, etc) do better with softer colors. Masculine niches (fishing logs, workout trackers) do better with darker colors or earth tones. I know it sounds obvious but you’d be surprised how many people ignore this.

Pricing Strategy Nobody Talks About

Start at $6.99 for a 110-page notebook. See what happens for two weeks. If you’re getting sales, test $7.99. Then $8.99. I’ve got books at $11.99 that sell just fine because they’re specific enough that people don’t care about saving two bucks.

But here’s the thing – you need to be making at least $2 per sale or it’s not worth the effort. Do the math in KDP’s calculator before you publish. Factor in the trim size, page count, and your price. If you’re only making $1.20 per sale you either need to raise the price or lower your page count or pick a different trim size.

Wait I forgot to mention – 6×9 is the most common trim size for notebooks and it’s usually the most cost-effective. 8.5×11 has higher printing costs but you can charge more. 5×8 is cute for niche stuff but harder to sell. I stick with 6×9 for probably 80% of my books.

Keywords Are Your Money Maker

You get seven keyword slots on KDP. Use all seven. Don’t waste them on single words like “journal” or “notebook” because you’ll never rank for those. Use phrases people actually search.

My cat just jumped on my keyboard but anyway – tools like Publisher Rocket (formerly KDP Rocket) help you find keywords with decent search volume and low competition. It costs like $97 one-time but I’ve made that back hundreds of times over. You can also do it manually by just searching on Amazon and seeing what comes up.

The Keyword Research Process

I look for keywords with:

• At least 2000 searches per month
• Competition score under 40 (if using Publisher Rocket)
• Top results with under 200 reviews

Then I use variations of those keywords across my seven slots. Like if my main keyword is “fishing log book” I might also use “fishing journal for men” “fisherman log book” “fishing trip tracker” etc. Related but different.

Put your best keyword in your title. Amazon weighs title keywords heavily. Then subtitle. Then use the seven backend keyword slots for variations and related terms.

How Many Books You Actually Need

This is where the passive income part comes in but it takes time. One book won’t make you money. Ten books might make you $50/month. You need volume.

I’ve got about 180 low content books published right now. About 40 of them make consistent sales. Another 60 make occasional sales. The rest just sit there. That’s normal. You’re playing a numbers game.

My goal when I’m in publishing mode is 3-5 books per week. That’s sustainable for me while doing other stuff. Some people do way more but they’re either outsourcing or have a ton of time. At that rate you can have 50+ books published in a few months.

The Compounding Effect

Here’s what happened with my account – first month I made $23. Second month $87. Third month $156. It kept climbing because each new book added a little more income AND some of my older books started ranking better. By month six I was at like $900. By month twelve I crossed $2k.

Now I’m consistently between $5k-8k per month from KDP, but that’s with 180+ books and almost two years of consistent publishing. It’s not fast money. It’s not get rich quick. It’s just… consistent and it builds on itself.

Seasonal Books Are Underrated

I publish Christmas planners in July. Halloween journals in June. Back to school stuff in May. You need lead time for Amazon’s algorithm to index your book and start showing it to people. Plus early birds exist.

My Christmas planner from 2022 still sells every November and December. I literally don’t touch it. It just makes money. That’s the passive part. Once it’s up and ranking, it keeps going.

Evergreen vs Seasonal Balance

I probably do 70% evergreen topics (fitness trackers, password logs, budget planners) and 30% seasonal. The evergreen stuff gives consistent baseline income. The seasonal stuff spikes and makes a ton during peak season then drops off.

Both are good. You want both. Don’t go all-in on Christmas stuff because then January through September you’re making nothing.

Advertising Usually Isn’t Worth It At First

Amazon PPC ads can work for low content books but honestly? I don’t run ads on most of my books. The margins are too thin. If I’m making $2.50 per sale and I spend $0.60 on ads to get that sale, it’s not terrible but it’s not great either.

I’d rather publish more books and let organic ranking do the work. Once you have a book that’s consistently selling 5+ copies per day organically, then maybe test ads. But not before.

The exception is if you’re in a competitive niche and need that initial boost to get reviews and ranking. Then a small ad campaign for the first month might help. I’m talking like $3-5 per day max.

Reviews Matter But Don’t Obsess

You need reviews to rank better and convert better but you can’t force them. Amazon will shut you down if you try anything shady. Just make a good product and some people will naturally leave reviews.

I’ve got books with 2 reviews that outsell books with 20 reviews because they’re in better niches or have better keywords. Reviews help but they’re not everything.

One thing that does help – put a small note on the last page of your book asking for a review if they found it helpful. Nothing aggressive. Just a simple “If you enjoyed this book, please consider leaving a review on Amazon.” Some people do it, most don’t, but it’s worth trying.

Scaling Up When You’re Making Money

Once you’re making a few hundred bucks a month you can reinvest. I started outsourcing interior design on Fiverr once I hit $500/month. Cost me like $5-10 per interior but saved me hours. Then I could publish more books faster.

Now I have a couple designers I work with regularly. I send them the specs and niche, they send me 3-4 interior options, I pick one. Takes them a day or two. Way faster than me doing it myself.

You can also outsource cover design but honestly I still do most of my own covers because I’m picky and it only takes 20 minutes in Canva once you’ve done it a bunch of times.

The Reinvestment Cycle

Make $500 → outsource some work → publish more books → make $1000 → outsource more → publish even more books. It compounds. But you gotta be patient with the early stages when you’re doing everything yourself.

Oh and track everything in a spreadsheet. Which niches work, which don’t, what your costs are, what your revenue is per book. I review this monthly and it tells me where to focus my efforts.

Look the main thing is just consistency. Most people publish 5 books, make $30, and quit. If you can push through to 50 books you’ll probably start seeing real money. By 100 books you should have a decent income stream. It’s not exciting but it works if you actually do it.
