On another group this was mentioned but not explained so I did a bit of research but am just going to ask the group as I do not right now have the time to follow this up . Has anyone used any of these tools? Top tools to find out what books are selling on Amazon include Book Bolt, Publisher Rocket, and BookBeam for in-depth competitor research, niche identification, and keyword tracking. These platforms offer Chrome extensions and databases to analyze Amazon Bestseller Ranks (BSR) and estimate daily sales, while the Amazon Seller App allows for manual scanning.
