We measured this shelf on 9 August: 144 relevant listings, a $14.50 median, 88 different shops per 100 listings. The price is the part worth looking at.

Measured on 9 August alongside a shelf that looks almost identical to it. Same size, same price, three points apart, and the whole gap comes from one component.

A busy shelf that held $9.99. Measured on 9 August against a category seven times its size that collapsed to $3.50. Density alone does not explain a price.

A thin shelf that is not fragmented. Around two listings per seller, a $5.26 median, and a score that loses every one of its points to price rather than to crowding.

We ran nearly 4,000 digital-product niches through our opportunity scoring engine. Only 10% scored 'strong.' Here's the data on what's saturated, what's wide open, and the one pattern every winning niche shares.

400+ Notion template listings analyzed on Etsy and Gumroad. Life admin, profession-specific systems, and ADHD planners are dominating in 2026. The data.

Generic Notion templates are saturated. Profession-specific and life-event templates are still wide open, with margins and demand that would surprise you.

Generic ADHD planners compete against more than 15,000 near-identical Etsy listings. The ones that stand out target a specific struggle, not a diagnosis. Here is the difference.

I scanned the nurse digital products niche. 8,000 results for nurse planner. Under 40 for clinical rotation sheets. Almost nobody is selling these.

Most creators skip grief journals because the topic is uncomfortable. That leaves a thin shelf at prices two to three times a generic journal, and a subject that demands care.

I check 4 things before entering any Etsy niche. Takes 20 minutes. Most niches fail at step 2. The ones that pass print money.

I found 10 niches with real buyers and fewer than 20 competitors each. Most sellers skip them because they look too small. They are wrong.

4 free ways to validate a digital product idea before you spend weeks building. Reddit demand mining, gap analysis, competitor scanning, and keyword checks.

One product idea, designed once for two marketplaces. How KDP paperbacks and Etsy digital files differ, what translates between them, and what has to be rebuilt.

I published my first KDP coloring book with zero design skills, into a category with four competing titles. The tools, the interior setup, and what I got wrong.

Sell digital products on Gumroad with no audience. The free traffic sources that actually work in 2026, the listing formula that converts, and the setup mistakes to skip.

We analyzed 200+ niches. 193 were oversaturated. These 11 have strong buyer demand and almost no competition, each scoring 75+ on our Opportunity Index.

What can actually be measured about a Notion template niche before you build, what no tool can measure, and why niche focus decides more than template quality.

47 products tested. The few that went anywhere shared one pattern: a specific audience, a specific problem, and a price above $14 on a shelf that was not already crowded.
