How to Monitor Amazon Competitor Prices and Reviews Automatically (Without Keepa or Helium 10)

Your competitor dropped their price by $3 at 8 AM on Friday. The Buy Box algorithm responded by 8:15 AM. You found out on Monday morning when you opened your Seller Central sales report. That's the structural failure mode for most Amazon sellers: Amazon's pricing and review systems change continuously, but there's no automated monitoring layer. You're always finding out after the damage is done. This article walks through a complete Amazon price and review monitoring pipeline using Apify — including step-by-step setup, alert configuration, and cost comparison against Keepa and Helium 10.
