Amazon Sellers, massive Keepa Update: Keepa just dropped a silent update. Among them is this new filter, it's a bit like storefront stalking on steroids. You can now view the entire historical product catalog of any seller on Amazon with just their seller ID. Why is this helpful? As you come across your own replens, seasonal scores, or arbitrage buys you naturally notice similar sellers on all of your same listings. Instead of only reviewing their current catalog for new items to source you can now hunt for their items they are out of stock on but will be replenishing. Find a seller who seems to be hitting all your same stores? Now you can see what they crushed with last holiday to track down this year for yourself. Do you wholesale? Well now you just got access to your competitors entire catalog to reverse source distributors with. If this is any indication of where Keepa is moving we could have some even better updates to come. To test it out head to Keepa > Data > Product Finder and search for the section in my picture attached.
