From “too crowded” to a niche you can win

The whole loop happens on the Amazon page — no copy-pasting into another app, no waiting.

Step 1 Too crowded

Search a broad idea

“gratitude journal”

  • Demand High
  • Competing books ~4,000
  • Top sellers Strong

Big keyword, brutal competition. Hard to rank as a newcomer.

Step 2 Good gap

Refine to a niche

“gratitude journal for men”

  • Demand Medium
  • Competing books ~90
  • Top sellers Weak

Real demand, thin competition, beatable leaders. A niche worth doing.

Step 3 Ready

Grab the keywords

“One-click copy”

  • KDP keyword slots 7
  • Suggestions Auto-expanded
  • Copy 1 click

Decide “men’s gratitude journal,” then copy the 7 keywords Amazon lets you use.

Honest by design: Amazon never publishes search volumes, so we don’t invent precise numbers. Demand is shown as a clearly-labeled relative signal you can sanity-check yourself.

Questions

Honest answers

Why “relative signals” instead of exact search volume?

Amazon never publishes search volume. Every tool that shows a precise number is estimating — we just won’t pretend otherwise. You get a clearly-labeled relative signal you can sanity-check, instead of a fake-precise figure.

How is this different from $199 desktop tools?

Those are desktop apps you pay $199 for and run outside your browser. This lives right on the Amazon page you’re already looking at, with an honest free tier and an affordable plan if you upgrade.

How is it different from the free overlay tools?

The free tier gives you real, usable data every day — not blurred numbers or a trial that’s empty two minutes in. And it’s built to load fast instead of spinning forever.
