How to Find Winning Products: The Method Without Expensive Tools

"Which product should I sell?" is the question many store founders get stuck on. This article shows you how to find winning products without paying for expensive spy tools or product lists, and how to vet a product before you spend money on inventory and ads. With a focus on the German market and German law. It's part of the overview Products & assortment in Shopify.

What a winning product really is

A winning product isn't an item with magical powers. It's a product you can sell to a reachable target audience at a price that leaves a profit after all costs. The same product can be a winner for one store and a loss for another, depending on price, presentation, target audience and ad costs.

Check every idea against these criteria:

Niche, product or store first?

Start with the target audience and the product, not the store. A store can be built in a day. A product nobody needs can't be saved by even the most beautiful theme.

On the question "one store per niche or one big store with categories?": for beginners, a store with one clear theme is best. "Water sports, yoga and fishing" in one store looks random and doesn't build trust. A general store is suitable at most for testing, but it's a dead end for a brand. Several stores are possible, but each needs its own Shopify subscription, its own legal texts and its own maintenance.

If you don't know which niche: pick one you know well or whose target audience you understand. You'll write better product copy, spot poor-quality goods faster and know where your customers spend time online.

When do you add more products?

Only once the main product sells and you know who's buying. Then you add, in the same store, exactly what these customers also need: accessories, refill packs, a larger version, a bundle. Opening a separate store for every new product rarely pays off, because reviews, customer list and trust start from zero each time. A second store only makes sense if the new product has a completely different target audience. The pros and cons of the store types are weighed in One-product store, niche store or general store?

Step 1: Find winning products with free sources

The goal of this step is a list of 20 to 30 ideas. Don't evaluate yet, just collect.

• TikTok: Search for hashtags like #tiktokmademebuyit or for terms in your niche. Look for videos with lots of comments like "Where can I get this?". The TikTok Creative Center shows you successful ads and trends for free.
• Meta Ad Library: Shows all active ads on Facebook and Instagram, filterable by country. Search for terms like "versandkostenfrei" (free shipping) or product names. A product that a store has been advertising for weeks with many ad variations is probably selling. Ads served in the EU come with additional transparency details.
• Amazon bestsellers: The bestseller, "New Releases" and "Movers & Shakers" lists on Amazon.de show what's being bought in Germany right now. The one- to three-star reviews tell you what customers dislike about the existing product.
• Forums and communities: Reddit, Facebook groups and specialist forums in your niche. Recurring questions and complaints are product ideas.
• Your own everyday life: What did you last buy because a problem annoyed you?

Supplier platforms like AliExpress or CJ aren't a good source of ideas. There you only see what exists, not what people in Germany want to buy. They only come into play in step 5.

Step 2: Check demand and competition

Demand

• Google Trends: Set the country to Germany and the time range to five years. Is interest rising, stable, or was it a short hype? If you see the same peaks every year, the product is seasonal.
• Google search: Enter the product term and look at the autocomplete suggestions and "Related searches". This shows you how people search for it in German.
• Amazon: How many reviews do the top listings have? Many reviews mean real demand, but also strong competition.

Competition

• Who already sells the product in Germany, at what price, with what delivery time?
• Is the product available on Amazon with Prime for €9.99? Then you need a significantly better offer to justify €29.90.
• What could you do better: a bundle, better quality, better images, German-language service, faster shipping from the EU?

Competition isn't a deal breaker. It proves demand. The deal breaker is when you can't find a reason why someone should buy from you instead of the competition.

Hype, evergreen or seasonal?

The five-year curve in Google Trends shows you one of three patterns:

• Short hype: a steep rise within a few weeks, often after a viral video. If you can see it in Trends, you're usually already late, and long delivery times eat up the window. Risky for beginners.
• Evergreen: a stable or slowly rising curve. Less spectacular, but predictable. Usually the better choice for a first store.
• Seasonal: the same peak every year, for example for heated blankets or pool accessories. Start with enough lead time so that samples, photos and tests are done before the rise. If the season is almost over, prepare for next year or pick a product for the coming season.

Hardly any search volume isn't automatically a no: some products nobody searches for because nobody knows they exist. Those sell through videos. In that case, though, the organic test from step 5 has to show real interest.

Step 3: Calculate the margin

This is where most ideas fail, and that's a good thing. For every product on your shortlist, calculate: gross selling price minus VAT, minus purchase cost including shipping and customs, minus packaging, shipping to the customer, payment fees and returns. What's left is your room for advertising and profit.

What this looks like in concrete numbers is shown in the article Pricing calculation for your online store, with a complete worked example. There you'll see: for a product at €49.90 with a €12 purchase price, just under €19 per order remains before advertising. If you want to sell with paid ads, products with only €10 to €15 of room before advertising are usually too tight.

Step 4: Legal deal breakers

Many viral products from US videos can't simply be sold in Germany. Cross these ideas off right away or check them very thoroughly:

• Brands and designs: Copies of well-known brands, fan merchandise with protected characters or logos. That's trademark infringement and quickly leads to expensive warning letters (Abmahnungen). Supplier product images aren't automatically free to use either, see Product images & trademarks in your store.
• Electrical and electronic devices: Need CE marking and, in Germany, registration with stiftung ear (German) before sale. Devices with batteries also fall under the battery rules.
• Toys, cosmetics, dietary supplements, medical devices: Strict safety and labeling requirements. Not suitable for beginners with goods from an unknown source.
• Product safety (GPSR): For every product, you must state the manufacturer with postal address and electronic address in your store, and for manufacturers outside the EU, also a responsible person in the EU. If your supplier can't provide this, you can't offer the product in a legally compliant way.
• Packaging: If you ship packaged goods to end customers in Germany, you must register in the LUCID packaging register.

Whether a product needs and has CE marking can't be reliably determined from the product description on CJ or AliExpress. Ask the supplier for the EU declaration of conformity and the test reports. If you don't get them, drop the product. Which product groups are completely off-limits in Germany or need a permit is shown in Prohibited & regulated products. The other duties for your store are covered in Shopify legal requirements in Germany.

Step 5: Order a sample and test

If two or three products are left after steps 1 to 4, it's time for practice.

1. Find a supplier: With dropshipping, you don't need to contact the supplier beforehand. You import the product via an app, and orders are passed on through it. Which suppliers reliably deliver to the EU is covered in Finding reliable dropshipping suppliers, and which app fits in AutoDS vs. Zendrop vs. DSers vs. CJ. If you only know the product from a video, you can find vendors via an image search such as Google Lens or the image search in AliExpress and the dropshipping apps.
2. Order a sample: Order the product yourself, like a regular customer from the supplier or via the app, to your address, and pay for it. That way you see the quality, packaging and real delivery time. And you have your own photo and video material. If a wholesaler requires minimum quantities of 100 or 500 units, ask for a sample order or test first with a supplier without a minimum quantity.
3. Test organically: Post two or three short videos on TikTok or Instagram Reels. Comments and questions give you a first signal, without an ad budget.
4. Test with paid ads: Decide beforehand the maximum you'll spend and when you'll stop. The basis is your break-even CAC from step 3. If no order comes in at a profitable price before the stop point, the product isn't a winner in this form.

How to set up your first campaign is explained in Meta Ads for Shopify beginners.

Evaluating the test: continue, change or stop?

Before you discard a product, check where it's getting stuck:

• Hardly any clicks on the ad: The video or angle isn't convincing. Test a different hook, a different problem or a different target audience.
• Many clicks, no purchases: The problem is more likely on the product page or in the offer, i.e. price, shipping costs, delivery time or trust. Work through the causes with No sales on Shopify? The diagnostic checklist.
• Purchases, but no profit: Check whether a bundle or a higher price increases the room. If not, the product isn't a winner in this form.

More budget is only worth it once the product sells over several days at a cost per order below your break-even CAC, not after a single good day.

Why purchased product lists rarely work

"Winning product" lists and spy tools sell the same products to all their customers. When a product shows up there, thousands of other stores see it too. The price drops and ad costs rise. In addition, most lists come from the US market and take neither German prices nor German law into account.

Spy tools can save time later, once you know what you're looking for. At the start, though, they don't replace the work from steps 2 to 4. And monthly tool costs in the double- to triple-digit range are money missing from your ad budget. The same applies to the product suggestions in dropshipping apps like AutoDS or Zendrop: they show what others are selling right now, but don't replace your own check of demand, margin and legal issues.

When a product works, that's the starting point, not the goal. A store only becomes stable in the long run once it no longer just resells products everyone else has too. What that path looks like is covered in From dropshipping to your own brand.

FAQ

How do I know whether a product is a winning product?

You only know for sure in the test: it sells at a price that leaves a profit after all costs including advertising. Before that, there are good indicators: visible demand in Google Trends and on social media, competitors who have been advertising it for weeks, a clear benefit and enough margin. If one of these is missing, the risk is high.

Do I need to contact the supplier before I put a product in my store?

Not with dropshipping via apps like DSers, CJ or AutoDS. You import the product into your store, and orders are forwarded to the supplier via the app. Contact is still worthwhile: you need manufacturer details for product safety, declarations of conformity and reliable delivery times. Also, always order a sample before running ads.

One store for several niches or a separate store for each niche?

To start: one store with one clear theme. A mix of completely different niches looks untrustworthy, confuses customers and makes advertising harder. If you want to test several niches, test them one after another. Several stores are possible, but each costs its own Shopify subscription and needs its own legal texts, domain and maintenance.

Does the method also work for the German market?

Yes, it's actually designed for it. Many tutorials show US products and US prices. If you set Google Trends, the Meta Ad Library and Amazon to Germany, you'll see what's in demand here. One advantage: many competitors just translate US stores. With good German, EU shipping and proper legal texts, you stand out.

Can I sell a product I saw in a TikTok video?

In principle yes, product ideas aren't protected. Brands, protected designs and characters are off-limits, though. You can't simply take other people's videos and images for your ads. Create your own content with your sample or get a license. Also check whether the product may be sold in the EU at all.

How many products do I need to start?

Fewer than you think. For a test, one main product with a few matching add-ons, such as accessories or a bundle, is enough. A store with a hundred random products doesn't sell more than one with five well-presented ones. Focus on the product page, images and offer for the main product.

Can I use AI for product research?

Yes, as an assistant. ChatGPT, Claude or Gemini can help you collect ideas for a target audience, analyze hundreds of Amazon reviews for recurring complaints or set up a margin calculation. But AI doesn't know real sales figures, and statements about trends or the legal situation may be outdated or wrong. So you still do the check with Google Trends, the Ad Library and your own calculation yourself.
