Problems this category helps solve
Product research tools should not be judged by trend lists alone. Sellers need demand, margin, review pain points, competition, and ad pressure in one framework.
- Score your own demand and competition assumptions
- Check gross margin before other costs
- Count fixed themes in pasted reviews
Decision factors
- Whether data sources and update timing are clear
- Whether price bands match the target AOV
- Whether review samples support real pain-point analysis
- Whether competition and ad pressure leave room to test
Common mistakes
- Buying inventory from a hot list alone
- Checking sales but not refunds or negative reviews
- Ignoring freight volume and ad cost
- Treating one marketplace signal as total market demand
