Every beginner has the same fear: “what if I pick the wrong product?” Here’s the truth — product picking isn’t a vibe call, it’s a checklist. Run every idea through these five criteria and you’ll eliminate 80% of bad calls before you’ve spent a dollar.
This is the exact process we use on every new Shopify store before committing inventory, ad spend, or a full week of setup. It takes 30 minutes per product idea.
The 5-criteria filter
A winning Shopify product hits all five. If it fails any single one, skip it — there’s always another idea.
1. Demand — someone is already buying
You’re not creating demand, you’re catching it. Look for existing search volume, existing competitors with sales, and existing community conversation. If nobody’s talking about it, you can’t afford to be first.
2. Margin — 3× markup minimum
If the cost is $10, your selling price needs to be $30 or higher. That’s not greed — that’s survival. You’ll lose 10–15% to ad costs, 5% to payment fees, and 20% to returns or discounting. Without 3× markup, you can’t afford to acquire customers.
3. Shipping — fits in a padded mailer
Heavy or oversized products destroy your margins. Aim for anything that fits in a 25cm × 18cm padded mailer and weighs under 500g. Your shipping cost should never exceed 12% of product price.
4. Emotional hook — solves a problem or signals identity
Best-selling products either solve a problem the customer recognises (“my dog destroys every toy”) or signal identity (“I’m a coffee person”). If you can’t finish this sentence — “This product is for {specific person} who wants to {outcome}” — it’s too generic.
5. Repeat purchase or bundle potential
One-off purchases force you to keep paying for new traffic. Products that ship monthly (consumables), get re-bought seasonally (clothing), or sell in sets (accessories) compound revenue. If your product can only sell once per customer, it needs to be high-margin enough to justify the acquisition cost alone.
3 free tools for validation
TikTok search — real-time demand
Search your product idea directly on TikTok. Look for videos over 100K views showing the product in use. If creators are making organic content about it, there’s heat. No TikTok presence? Demand is either dead or hasn’t arrived.
Google Trends — direction
Pop your product name into trends.google.com. You want the 12-month line flat or rising, never declining. Set the region to AU + US. Seasonal spikes are fine if you can launch before the next peak.
AliExpress order count — proof of sales
Find the product on AliExpress. Sort listings by “Orders” descending. Any item with over 5,000 lifetime orders and a 4.5+ rating has proven demand. This signals real buyers, not just search interest.
The margin math: $3 → $30 rule
If your all-in cost (product + shipping + payment fees) is $3, sell for $30. Here’s why:
- $3 — product + shipping + Shopify Payments fee
- $6 — Meta/TikTok ad cost to acquire one sale
- $3 — discount / return / customer service buffer
- $3 — Shopify plan + apps (amortised per sale)
- $15 — net profit per unit
That’s a healthy 50% net margin. At 2× markup you’d be at 17% net — one bad ad week wipes you out. At 3× you have room to survive mistakes.
Red flags — products to skip in 2026
- Fashion basics (plain t-shirts, jeans) — margin impossible against Shein
- Generic phone cases — commoditised to zero profit
- Fragile items (ceramics, glass) — return rates kill you
- Products requiring fit (shoes, detailed clothing) — 30%+ return rate without a try-on option
- Seasonal-only products without a year-round angle — you starve 9 months a year
- Anything with a brand logo you don’t own — trademark risk
