KDP Lens 제작자: US Tech Automations

KDP Lens puts the book information already visible on Amazon.com into a compact panel, so self-publishers can review it without switching tools.

On book pages: observed overall Books or Kindle Store rank, separate category positions, price, review count and publisher. Missing or ambiguous overall ranks appear as Unavailable.
On bestseller lists: the displayed list positions and titles.
On search results: local review averages and a rough publisher-text grouping. These groupings are heuristics, not measured market share.

KDP Lens does not predict sales or earnings. It does not log into Amazon or KDP, publish books, or transmit Amazon page text.
