These are the closest head-to-head on this list: both are Amazon market-intelligence tools covering brands, sellers, and products. Choose Ecominsights if you want month-by-month sales history — 12 months for any brand or ASIN, on a free ($0/mo) plan. Choose SmartScout if you want deeper wholesale and seller-network intelligence (traffic graph, seller maps) from a more established tool (from $29/mo). 

Quick comparison

Sales history — Ecominsights wins

Ecominsights shows how much any Amazon brand or ASIN sold each month for the past 12 months, on a free ($0/mo) plan. SmartScout provides estimated monthly sales, but Ecominsights’ focus is the month-by-month history — how a brand or product trended across the year. If historical sales movement is what you’re after, Ecominsights is built for it.

Wholesale & seller-network depth — SmartScout wins

SmartScout is purpose-built for wholesale and seller research: its traffic graph, seller maps, and brand/category intelligence show who controls a market and how buyers reach products. Ecominsights covers brands and sellers too, but it does not offer SmartScout’s wholesale-specific network tooling. For arbitrage, wholesale sourcing, and seller-network analysis, SmartScout is deeper.

Keyword data — Ecominsights wins

Ecominsights tracks keyword search-volume and CPC trends over 12 months across 5M keywords; SmartScout’s keyword research is basic. If keyword trend data matters, Ecominsights is the stronger of the two.

Price & free access — close, Ecominsights broader free tier

SmartScout starts at $29/mo ($25 annually) — cheaper than Ecominsights’ $39/mo Basic — and offers a free Chrome extension (~1,000 lookups/month). But Ecominsights’ free plan includes the full 12-month sales history, which SmartScout gates to paid tiers. Cheapest paid entry: SmartScout. Most data on a free plan: Ecominsights.

Where SmartScout wins (the honest list)

• Wholesale intelligence: traffic graph, seller maps, and category-control analysis Ecominsights doesn’t have.
• Maturity & trust: longer track record and established user base; Ecominsights launched in 2026.
• Cheapest paid entry: $29/mo vs Ecominsights’ $39/mo.
• Archive depth: longer baseline; Ecominsights history is 12 months, not years.

Who should choose which?

• Choose Ecominsights if: you want 12-month brand/ASIN sales history and keyword trends, with the data on a free plan.
• Choose SmartScout if: you do wholesale/arbitrage or seller-network research and want the deepest market-control tooling.
• Use both if: you want SmartScout’s wholesale maps plus Ecominsights’ historical sales/keyword trends.
