Before you spend another weekend making a book or printable, find out in two minutes whether the niche is letting new sellers in.

Dear Friend,

If you've ever finished a puzzle book or a printable, uploaded it, checked your dashboard every day for a week… and watched nothing happen — please read this short letter all the way through.

Because there's a good chance the book wasn't the problem.

The niche was.

Here's what I mean. Most of us pick a niche with one of two questions: "Is it big?" or "Is it low-competition?"

Both sound smart. Both can walk you straight into a wall.

A big niche can be sewn up by listings with thousands of reviews that have sat at the top for years. And a "low-competition" niche is very often empty for the simplest reason there is: nobody's buying there. You only find out after the work is done.

There's a better first question. It's the one NicheSeeker was built to answer:

Is this niche letting new sellers in — right now?

You can answer it by hand. Search the keyword. Open each of the top 16 results, one at a time. Write down the sales rank, the publish date, the rating, the review count. Work out which ones are new and already selling. Look for a top seller that buyers are grumbling about. Then do it all again for the next keyword.

It works. It also eats an evening per keyword — which is exactly why almost nobody does it.

NicheSeeker does that legwork for you, on the page you're already looking at. Open the side panel and a small strip appears under every result. A score tells you how open the niche looks, and the reasons are written out in plain English. Two questions, answered. Usually in about the time it takes to read this paragraph twice.

Let me show you the three ideas it's built on.

Here's some of what you'll see the first time you open it:

• Why "low competition" is often a warning sign — and the one signal that tells you more.
• The 90-day test: is anything launched in the last three months already selling on page one? (If yes, buyers here try new sellers.)
• How a 3.6-star bestseller can be a real opening on the page — and how NicheSeeker spots it for you.
• An estimate of monthly sales under every Amazon result, worked out from its sales rank, so you can compare books at a glance. (Estimates, labelled "est." — Amazon doesn't publish sales.)
• A 0–100 Open Door score with the reasons written out, so you know why a niche looks open or closed — not just a number.
• On Etsy: which listings come from new shops that are already ranking, which are on sale, and whether a price sits above or below the niche's median.
• A book page view with the sales rank, categories, estimated monthly sales and estimated royalty per copy, in one place.
• One-tap filters for New & ranking and Weak leaders, so the interesting books jump out of the list.
• A place to save the niches you checked in your account, so you can come back and compare.
