Start with the basic formula

If you monitor 50 products across Amazon, Google Shopping, eBay, and Reverb, that is 200 product URL checks for one full pass.

Products × monitored sites = daily checks for one full sweep.

Examples

  • 50 products × 4 included sources = 200 checks.
  • 500 products × 7 sources, including 3 custom URLs = 3,500 checks.
  • 1,000 products × 4 included sources = 4,000 checks.

Why this matters commercially

Not every customer needs the same monitoring density. Some only need a daily pass across Amazon and Google Shopping. Others want broader marketplace coverage plus a handful of priority dealer sites. A clean check model lets a plan fit both without pretending those workloads are identical.

How to choose the right tier

If a team mostly wants one daily pass across a smaller catalog, a tighter entry plan is enough. If they want more products, more sites, or multiple full daily sweeps, the right tier is the one that gives room for those operations without forcing constant micromanagement.
