The Zoloo product tracker is one of the most powerful tools for bol.com sellers who want to grow seriously. Whether you are just starting out or already have an established assortment - without solid product research you risk buying items that barely sell or have too low margins. In this comprehensive article we explain exactly what the Zoloo product tracker does, how to use it optimally and why data-driven product research makes the difference between profit and loss.
What is the Zoloo product tracker?
The Zoloo product tracker is an advanced tool within the Zoloo platform that lets you monitor, analyze and compare products on bol.com. The tool collects real-time data on sales performance, price developments, competition and market trends - and presents it in a clear dashboard. This enables you as a seller to make informed decisions about which products to sell, when to adjust your price and where new opportunities lie.
Unlike manual searching on bol.com - which takes hours and only provides a snapshot - the product tracker offers continuous monitoring and historical data. This gives you a strategic advantage over sellers who rely on gut feeling.
Key features of the Zoloo product tracker
The product tracker offers a wide range of features specifically designed for bol.com sellers. Below you’ll find an overview of the core functions:
| Feature | Description | Benefit |
|---|---|---|
| Sales data tracking | Daily updates of estimated sales numbers per product | Know exactly how much a product sells before you purchase |
| Price monitoring | Track price changes of competitors in real-time | Optimize your pricing strategy based on market data |
| Competition analysis | View number of sellers, buy-box holder and offer overview | Avoid oversaturated markets and find niches |
| Historical trends | View sales and price trends over weeks and months | Spot seasonal patterns and growth markets |

How does product research work with Zoloo?
Product research with the Zoloo product tracker follows a series of logical steps. Below we describe the full process from the initial search to the final product decision.
Step 1: Market exploration
Start by exploring bol.com categories via the Zoloo product database. Filter on criteria such as minimum sales volume, maximum number of sellers and desired price range. The database contains millions of bol.com products with up-to-date data, so you can quickly identify promising markets.
Step 2: Add products to your tracker
Once you’ve found interesting products, add them to the product tracker. The tracker immediately starts gathering sales data, price changes and competition information. The longer you follow a product, the more reliable the data becomes - we recommend tracking for at least two weeks before making a purchasing decision.
Step 3: Analyze data
After a sufficient tracking period, analyze the collected data. Pay attention to the following indicators:
- Average daily sales - At least 3-5 sales per day is a good start for most categories
- Price stability - Products with large price fluctuations indicate a price war; avoid them
- Number of competitors - Fewer than 5 active sellers offers the best chances
- Seasonal pattern - Check whether sales are stable year-round or strongly seasonal
- Profit margin - At least 20-30% net margin after all costs is a healthy guideline
Step 4: Profit calculation
Use the profit calculator to compute your exact net margin. Enter your purchase price and the tool automatically calculates the bol.com commission, shipping costs (including LVB costs if applicable) and VAT. This way you know precisely what you keep per sold product.
Zoloo product tracker versus manual research
Many new sellers try to do product research manually - they scroll through bol.com, look at best-sellers and estimate sales numbers. This often leads to costly mistakes. Below we compare the two approaches:
| Aspect | Manual research | Zoloo product tracker |
|---|---|---|
| Time investment | Hours per product | Minutes per product |
| Data accuracy | Estimates based on gut feeling | Real-time data and historical trends |
| Competition insight | Manually counting sellers | Automatic overview with purchase block analysis |
| Price monitoring | Daily manual checks | Continuous automatic monitoring |
| Seasonal analysis | Not possible without months of tracking | Historical data instantly available |
| Scalability | Maximum 5-10 products at once | Hundreds of products tracked simultaneously |
| Cost per mistake | High - wrong purchase costs hundreds of euros | Low - data prevents most purchasing errors |
Why sellers choose Zoloo?
There are several tools on the market for bol.com product research, but Zoloo stands out on a number of key points. Below are the main reasons why more than 20,000 sellers use Zoloo:
All-in-one platform
Where other tools limit themselves to a single function (only product research or only a profit calculator), Zoloo offers a complete ecosystem. Besides the product tracker you get access to the keyword explorer, ranking checker, AI listing generator, sales dashboard and more. This means you don’t have to switch between different tools - all your data lives in one place.
Specifically for the Dutch market
Zoloo is 100% focused on bol.com and the Benelux market. While international tools like Jungle Scout or Helium 10 target Amazon, Zoloo is built for the specific challenges of bol.com sellers. The commission structure, logistics via LVB and bol.com-specific ranking factors are all integrated.
Reliable and up-to-date data
The product tracker is continuously updated with the latest bol.com data. Sales estimates are based on advanced algorithms that take BSR changes, seasonal effects, and category-specific factors into account. This delivers more accurate estimates than manual methods.
User-friendly dashboard
The Zoloo dashboard is built with ease of use as a priority. Complex data is shown in clear charts, tidy tables and action-oriented insights. Even if you have no experience with data analysis, you can start product research right away.
Common mistakes in product research
Even with a powerful tool like the Zoloo product tracker, sellers sometimes make mistakes. Here are the five most common pitfalls and how to avoid them:
- Tracking for too short - Two days of data isn’t enough. Track at least 2–4 weeks for reliable conclusions, especially for seasonal products
- Focusing only on volume - High sales volume is attractive, but if there are 50 competitors and margins are low, it’s not a profitable product
- Ignoring shipping costs - Large or heavy products have significant shipping fees on bol.com. Always calculate your net margin including all logistics costs
- Seeing one product as a rescue - Diversify your assortment. Successful sellers have 10–50 products that together generate stable revenue
- Ignoring trends - A product that sells well now but has been declining for three months isn’t a good investment. Always look at the long-term trend
Product tracker combined with other Zoloo tools
The power of the Zoloo product tracker really shines when you combine it with other tools in the Zoloo ecosystem:
- Keyword explorer - Discover which search terms buyers use to find products. Combine this with product data to find items that are heavily searched but have little competition
- Ranking checker - Monitor your position in the bol.com search results. When you sell a product, you want to know if you’re discoverable for the main search terms
- Listing generator AI - Optimize your product page with AI-generated titles and descriptions that exactly match the search terms from your keyword research
- Chrome extension - View product data directly on bol.com while you browse the platform. Ideal for quick product scans without switching to the Zoloo dashboard
- Email campaigns - Once you’ve found and are selling a profitable product, use email marketing to gather reviews and encourage repeat purchases
Successful product research strategies with the Zoloo product tracker
To get the most out of the Zoloo product tracker, there are several proven strategies that successful sellers use. These strategies help you systematically identify profitable products and minimise risks.
The niche strategy
Instead of competing in large, crowded categories like electronics or books, successful sellers focus on specific niches. Use the product tracker to find sub-categories where demand is high but the number of sellers is limited. Think of specialised hobby items, seasonal garden products or niche office supplies. The product database helps you discover these hidden gems by filtering on high sales volume combined with low competition.
The seasonal strategy
Smartly leveraging seasonal patterns is one of the most effective ways to boost your revenue. The product tracker shows historical sales data that lets you predict when demand for certain products will rise. Start purchasing three to four months before the season - think garden furniture in January, swim gear in March and Christmas decorations in August. Buying early lets you benefit from lower purchase prices and have stock ready when the peak begins.
The expansion strategy
Once you’re selling a profitable product, use the product tracker to find related items that can complement your range. Customers who buy product A are often also interested in product B and C. By offering complementary products you not only increase revenue per customer, but also strengthen your position in the category. The tracker helps you identify which additional products have the best sales-to-competition ratio.
The buy-block strategy
Winning the buy block is crucial for your sales success. Use the product tracker to identify products where the buy block regularly rotates between sellers - these are products where you have a realistic chance to win the buy block. Avoid products where bol.com itself holds the buy block or where one dominant seller always wins. The competition analysis in the tracker gives you exactly this insight.
Pricing and plans
Zoloo offers several subscription options, from a free 14-day trial to comprehensive packages for professional sellers. All plans provide access to the product tracker. Check the current pricing page for a detailed overview of what each package includes.
A key advantage of Zoloo over some competitors is the transparent pricing model. You pay a fixed monthly fee with no hidden costs or variable surcharges per monitored product. This makes it easy to forecast your expenses, no matter how many products you track.
