Method 1: Amazon Best Sellers and Movers & Shakers
How to Use It
Amazon publishes publicly accessible lists of the top-selling products in every category. Find them at amazon.com/bestsellers (or the respective country domain). Additionally, the "Movers & Shakers" list shows which products had the biggest ranking jump in the past 24 hours.
Go systematically through relevant categories and subcategories. Note products that appear in the Top 100 and that you can realistically source (for arbitrage: find cheaper in retail or online stores; for wholesale: purchase from the manufacturer or distributor).
Advantage
You see in real time what is actually selling right now. The data comes directly from Amazon — no estimates, no projections. The Movers & Shakers list is particularly valuable for spotting emerging trends early, before the competition catches on.
Limitations
Best seller lists show sales rank but not volume. You know a product is ranked fifth in its category, but not whether that means 50 or 5,000 sales per month. Additionally, top products are often heavily contested — many sellers see the same list and draw the same conclusions.
When a Paid Tool Makes More Sense
When you need concrete sales volume numbers, not just relative rankings. Tools like Jungle Scout or Helium 10 estimate monthly sales per ASIN and provide historical data that free lists do not offer.

Method 2: Google Trends
How to Use It
Go to trends.google.com and enter product terms that interest you. Google Trends shows you relative search interest over time — for both Google Search and YouTube. You can filter by region, compare time periods, and discover related search terms.
Compare multiple product categories against each other to identify seasonal patterns. A product with high search volume in January and barely any interest in July requires different inventory management than a product with year-round stable demand.
Advantage
Google Trends is completely free, requires no account, and delivers data that extends beyond Amazon. You spot general demand trends before they show up in Amazon sales figures. Particularly powerful: comparing multiple terms simultaneously to gauge relative demand.
Limitations
Google Trends shows relative search interest, not absolute numbers. A trend from 20 to 80 could mean searches increased from 200 to 800 — or from 20,000 to 80,000. Without context knowledge, interpretation is difficult. Also, Google Trends measures Google search, not Amazon search. The correlation is high but not perfect.
When a Paid Tool Makes More Sense
When you need absolute search volumes on Amazon. Helium 10 Cerebro or Jungle Scout Keyword Scout provide estimated monthly Amazon search volumes that Google Trends cannot deliver.

Method 3: Keepa (Free Version)
How to Use It
Keepa (keepa.com) is primarily known as a price tracking tool. The free version already offers valuable information: you see the price history of any Amazon product over months or years. Install the Keepa browser extension, and a price chart automatically appears on every Amazon product page.
For product research, use Keepa like this: check whether a product's price is stable or fluctuates sharply. A stable price indicates an established market with predictable margins. Heavy price swings indicate intense price competition or seasonal effects.
Advantage
Historical price data is invaluable for margin planning. When you see that a product has never sold below EUR 25 in the past 12 months, you can calculate with a stable price floor. This reduces your risk significantly.
Limitations
The free version shows only Amazon prices and marketplace prices, but no estimated sales figures. For sales rank tracking and detailed sales estimates, you need Keepa Premium (approximately EUR 20/month). For a detailed comparison, see our Jungle Scout vs. Helium 10 vs. Keepa guide.
When a Paid Tool Makes More Sense
When you need sales rank history data and estimated sales per ASIN. Keepa Premium or a full suite tool like Helium 10 provides these data points.

Method 4: Amazon Search Suggestions (Autocomplete)
How to Use It
Open Amazon and start typing a search term. Before you press Enter, Amazon displays a list of search suggestions. These suggestions are based on actual customer searches — Amazon is showing you what buyers are actively looking for.
Systematic approach: type a broad term (e.g., "Bluetooth") and note all suggestions. Then extend with letters ("Bluetooth a," "Bluetooth b," "Bluetooth c," and so on) to discover even more long-tail keywords. This method yields hundreds of relevant search terms in a short time.
Advantage
You get direct insight into Amazon's internal search demand — for free. The suggestions are current and reflect what customers are searching for right now. Long-tail keywords from autocomplete are often less competitive than main keywords, revealing opportunities for niche products.
Limitations
You see the search terms but not the search volume behind each one. "Bluetooth headphones small" might be searched 50 times or 50,000 times per month — you do not know. Also, autocomplete shows only the most popular suggestions; less common but potentially profitable niches do not appear.
When a Paid Tool Makes More Sense
When you need search volume data for the keywords you have found. A tool like Helium 10 Magnet or Cerebro provides estimated monthly search volumes for every keyword.

Method 5: Brand Analytics (With Brand Registry)
How to Use It
If you have registered your own brand with Amazon (Brand Registry), you have access to Brand Analytics in Seller Central. There you find the "Top Search Terms" reports: Amazon shows you the most-searched terms on the platform, including the three most-clicked ASINs per search term.
Use this data to find demand gaps: if the top 3 products for a search term have poor reviews, high prices, or limited selection, that could represent an opportunity for you.
Advantage
These are official Amazon data, not third-party estimates. The accuracy is significantly higher than any external tool. You see not only what is being searched but also which products receive clicks — and which do not.
Limitations
Brand Analytics is available only to sellers with Brand Registry. This means you need a registered trademark. For arbitrage and wholesale sellers without their own brand, this method is not accessible. Also, Brand Analytics shows relative rankings, not absolute search numbers.
When a Paid Tool Makes More Sense
Brand Analytics is already free and in many cases superior to paid alternatives. A paid tool complements Brand Analytics when you need historical data, since Brand Analytics only covers current time periods.

Method 6: Social Media Trends
How to Use It
Platforms like TikTok, Instagram, and Pinterest have become strong indicators of emerging product trends. Products that go viral on TikTok ("TikTok made me buy it") often appear in Amazon best seller lists weeks later.
Search hashtags like #TikTokMadeMeBuyIt, #AmazonFinds, #AmazonMustHaves, and similar tags on TikTok and Instagram. Pay attention to products shown repeatedly by different creators — that indicates broad interest, not just a single viral clip.
Advantage
You spot trends before they reach Amazon. When a product is just starting to explode on TikTok, you have a window of 1-4 weeks before demand on Amazon picks up and competition follows.
Limitations
Not every social media trend translates into sustained Amazon sales. Many viral products have a short lifecycle: demand spikes explosively and falls just as quickly. If you purchase too much inventory and the trend passes, you are stuck with stock. Also, this method is very manual and difficult to systematize.
When a Paid Tool Makes More Sense
When you want to systematically track trending products instead of manually scrolling through social media. Tools like Exploding Topics or certain features in Jungle Scout aggregate trend data from multiple sources.

Method 7: Alibaba as an Inspiration Source
How to Use It
Alibaba.com is the world's largest B2B trading platform and primarily relevant for private label sellers. But even for wholesale and arbitrage sellers, Alibaba provides valuable insights: you see which products are in high demand at scale, what price ranges are typical, and which variations exist.
Browse Alibaba for product categories that interest you. Look for "Hot Products" and "Trending Products" on the homepage. Then compare Alibaba purchase prices with Amazon selling prices for a rough margin estimate.
Advantage
You get an overview of manufacturing costs and market prices worldwide. This helps you assess a product's viability before diving deeper into research. You also discover product variations and niches that are not yet well covered on Amazon.
Limitations
Alibaba prices are manufacturer prices for large quantities (often MOQ of 500-1,000 units). The actual landed cost (including shipping, customs, import VAT) is significantly higher. Also, a low manufacturing price says nothing about demand on Amazon — you need supplementary data to assess the sales side.
When a Paid Tool Makes More Sense
Alibaba provides supply data but not demand data. To validate the Amazon side (search volume, competition, estimated sales), you need an Amazon-specific tool. The combination of Alibaba research and a tool like Jungle Scout is the standard workflow for private label sellers. More details in our guide to profitable products.

Frequently Asked Questions (FAQ)
Can I find successful products entirely without paid tools?
Yes, especially in the early stages. The seven free methods in this article cover the most important research needs: demand trends (Google Trends, Movers & Shakers), price history (Keepa Free), search term analysis (Autocomplete), and trend detection (Social Media). A paid tool becomes valuable when you scale and need quantitative data (search volume, estimated sales) for data-driven decisions.
Which free method is the most important?
Amazon Best Sellers + Movers & Shakers combined with Keepa Free. The best seller lists show you what sells, and Keepa shows you whether prices are stable enough for calculable margins. This combination delivers the most relevant information with the least time investment.
How much time should I invest in product research?
As a beginner: at least 10-20 hours before purchasing your first product. Experienced sellers spend 2-5 hours per week on ongoing research to identify new products and monitor existing markets. Skipping or rushing the research phase is one of the most expensive mistakes you can make as an Amazon seller.
When does a paid research tool become worthwhile?
As soon as you regularly make purchasing decisions of EUR 500 or more. At those amounts, a tool costing EUR 50-100/month quickly pays for itself if it helps you avoid even a single bad decision per month. For a detailed comparison of the most popular tools, read our Jungle Scout vs. Helium 10 vs. Keepa comparison.
