Sell a Tight Mini Ebook and Watch It Compound

I spent six weekends in 2023 writing a 72 page ebook that earned me 180 euros in its first quarter. I then spent two weekends writing an 18 page companion piece that earned 640 euros in the same three months, on the same list, at the same time. The short one won on every metric that matters: completion rate, word of mouth, refund rate and hourly return on writing time. This page is the post mortem of that difference.

Three mistakes I made on book one

  1. I padded the word count. I had a 12,000 word idea and a 30,000 word ambition. The extra 18,000 words were filler, and buyers could feel it. Two of the three one star reviews mentioned that the book "drags in the middle".
  2. I priced it at 29 euros to justify the length. The high price paired with a thick PDF signalled a course without the course. Refund rate hit 7.5 percent in month one. The mini ebook at 12 euros now runs under 2 percent refunds.
  3. I wrote the cover last. The cover is the advertisement; I treated it as an afterthought. My mini ebook cover took 90 minutes in Figma using a template from the stock photo toolkit I describe in the stock photo and AI assets post. Conversion on the sales page climbed from 1.1 percent to 2.6 percent when I replaced the original cover with the template version.

The twelve euro price that stuck

I tested 7, 9, 12, 14 and 19 euros on the same listing across eight weeks using Gumroad's pricing A/B tool. The 12 euro tier won on revenue per visitor, and the 9 euro tier won on raw conversion rate, but refund rate was 3x higher on the lower tier. Net of refunds, 12 euros was the clear winner. After three testimonials arrived in week six, I nudged the price to 14 euros and revenue per visitor held, which is when I stopped tweaking and started writing book three.

What a mini ebook earns in month six

Month one: 310 euros, 26 sales, most from the launch email to a list of 1,400. Month two: 140 euros, 12 sales, pure organic. Month three: 220 euros, 18 sales, including 7 referrals from existing buyers. Month six: 280 euros, 23 sales, half from an unexpected mention in a neighbour operator's newsletter. The floor has sat between 180 and 340 euros a month ever since, with two spikes above 700 euros on promotional weeks tied to the Notion template launches.

John's rare tip

Write the table of contents before the first paragraph

I draft the full chapter list and the one sentence takeaway for each chapter before a single paragraph of prose. If the chapter list does not read as a coherent promise, the book does not exist yet. This alone killed two half written drafts that would have padded themselves to 40 pages of nothing. The TOC is also the exact skeleton of the sales page, so that work is not wasted even if the draft dies.

What I'd avoid

Do not send the launch email before the Gumroad listing has a single real testimonial, even a short one from a beta reader. My first mini ebook launched cold and converted at 1.1 percent. Book two shipped with two sentences from a beta reader and converted at 3.4 percent on the same list. Two lines of honest social proof moved the needle more than any pricing tweak did.

Frequently asked

Why under twenty pages rather than a full ebook?

Because the completion rate on a short PDF is five to six times higher than on a sixty page book, and a finished reader is a buyer who comes back. My first full length ebook had a 14 percent completion rate on the analytics. The 18 page version of the same material had 82 percent completion and twice the word of mouth referrals in month three.

What price point earns the most on a short ebook?

Between 9 and 14 euros. I anchor at 12 euros for the first month, nudge to 14 once I have three written testimonials, and keep a 7 euros launch price only for the first 48 hours. Below 7 euros the refund rate climbs to 6 percent in my logs because the buyer expected a course.

Is Gumroad still the right platform in 2026?

For solo sellers under 3,000 euros a month in sales, yes. The fees are higher than they were, but the discovery and checkout still convert better than my own Stripe link page on cold traffic. I migrate to a custom Stripe and Checkout page only when a product clears 3,000 euros a month consistently.
