Best for price tracking
Keepa Review
The definitive Amazon price-history and sales-rank tracker.
Overview
Keepa does one thing better than anyone: it shows you how a product's price and sales rank have moved over time. The free Chrome extension overlays history charts directly on Amazon listings; the paid plan adds price-drop alerts, stock monitoring, and category-wide tracking. It has no keyword or PPC tools — but for sourcing, arbitrage, and wholesale decisions, it's indispensable.

The verdict
Not a research suite and doesn't try to be. As a price-history specialist it's the best there is, and the price makes it an easy addition to almost any seller's stack.
