Most “ebook ideas” lists are a page of broad topics — fitness, money, cooking — that tell you nothing about what to write. Broad topics are where the competition is. The ebooks people pay for are narrower: one specific problem, for one specific person, solved completely.
So this page is mostly a method. The ideas at the end are examples of the shape, not a list to copy.
The three-question test
Run every idea through these before you plan a chapter. An idea that passes all three is worth writing; one that fails any of them usually needs narrowing, not abandoning.
- 1Who exactly is it for? Not “beginners” — “parents of a newly diagnosed coeliac child”, “freelance designers raising their prices”. If you cannot name the reader in one line, the idea is too broad.
- 2What do they have after reading it? A plan, a skill, a decision made, a problem gone. “Knowing more about X” is not an outcome anybody pays for.
- 3Are people already paying for something like it? Search Amazon, Etsy and Gumroad for the topic. Existing books with reviews mean there are buyers. Nothing at all usually means nobody is looking, not that you found a gap.
Competition is evidence of demand. Your job is not to find an empty shelf; it is to make the best book on a busy one, for a narrower reader.
Where good ideas come from
- What you already know. Your job, a hobby you are good at, something you learned the hard way. You do not have to be the world’s expert, just a few steps ahead of the reader.
- Questions people keep asking. Forums, Reddit threads, Facebook groups and comment sections are full of the same question asked a hundred times. Each one is a book’s worth of demand.
- One-star reviews. Read the bad reviews of popular books on your topic. “Too basic”, “no examples”, “written for Americans” — every complaint is a gap your book can fill.
- A transition. People pay most attention when something changes: a new baby, a new job, retirement, a diagnosis, a move abroad. A book that gets someone through the first month of a change has an obvious reader.
Match the idea to the right kind of book
The same idea can be a free lead magnet, a paid how-to guide, a workbook or a course companion. Choosing early decides the length, the price and where it sells. A quick check of how long each kind of ebook should be saves you writing three times what the reader wanted.

After the idea
Write the title as the outcome (“Price your design work with confidence”), plan the chapters before writing any of them, and decide where it will sell before you finish: Amazon KDP, your own site, Gumroad or Etsy. Then set a price with the ebook price calculator, and expect the selling to take real effort — your first ten ebook sales is honest about what that looks like.
