Questions

How accurate are the sales estimates?

They are estimates. Amazon does not publish sales, so Nichely converts the Best Sellers Rank with a public-style curve, separate for Books and Kindle Store. Use them to compare niches, not as exact numbers. The rank is a snapshot, so check a niche on more than one day before you commit.

Is it really free?

Yes. The niche check, keyword ideas and CSV export are free. Nichely Pro will add tracking and bulk tools.

Does Nichely see my Amazon account?

No. Everything runs in your browser. Nichely reads the search page and the book pages you analyze, and asks Amazon's search box for suggestions. It sends nothing to us. See the privacy policy.

Which Amazon stores work?

Amazon.com today. The sales curves are made for the US store, where most KDP sales happen.
