How do I use the Charts and Ranks & Prices panels?

Charts

Pick a time range: Dy, Wk, Mo, 3 Mo (the default), Yr or All. The chart can show:

• prices from Amazon, New, Used and the Buy Box, third-party FBA and FBM, Prime exclusive, Warehouse Deals and the list price
• the Sales Rank and Monthly Sold
• the Rating and the number of ratings
• the number of offers

Each time the sales rank line drops sharply, the product has probably sold, so lots of drops mean it sells often. A price that keeps falling usually means sellers are undercutting each other.

Ranks & Prices

A table of the BSR (Top %), the Buy Box, Amazon, Lowest FBA and Lowest FBM prices, the rank drops and Estimated Sales, for Current, 30, 90 and 180 days, and All.

Last Checked tells you how recent the data is, and Refresh reads it live again.

On Pro, Plug Keepa shows the same history in a box right on the Amazon page.
