To sell successfully on bol.com, comparing products on bol.com is one of the most important skills you need to master. By systematically analyzing and comparing products, you'll discover which ones are really profitable - and which ones you're better off avoiding. In this comprehensive guide, you'll learn exactly how to apply product comparison on bol.com in practice.
Why comparing products on bol.com is essential
The bol.com platform offers millions of products across hundreds of categories. Without a structured comparison method, you risk buying products that sell poorly, have too much competition, or don't offer enough margin. By making product comparison on bol.com part of your workflow, you significantly reduce these risks.
Successful sellers use comparison analyses to:
- Evaluate the sales speed of different products
- Map the competition intensity per product
- Calculate the profit margin after all costs (purchase price, bol.com commission, shipping costs, return percentage)
- Identify seasonal patterns and trends
- Analyze the quality of existing listings
The most important criteria for comparing products
When comparing products on bol.com, there are several factors to consider. Below, you'll find an overview of the most important comparison criteria, along with their weighting and explanation.
| Criterion | Weighting | What you measure | Ideal value |
|---|---|---|---|
| Sales speed | ★★★★★ | Number of sales per month | > 30 per month |
| Number of sellers | ★★★★☆ | Competition for the product | < 5 sellers |
| Profit margin | ★★★★★ | Net profit after all costs | > 30% margin |
| Average price | ★★★☆☆ | Selling price on the platform | €20 – €80 |
| Return percentage | ★★★★☆ | Percentage of returns in the category | < 5% |
| Seasonal dependency | ★★★☆☆ | Stability of demand over the year | Stable / slightly seasonal |
| Listing quality of competitors | ★★★☆☆ | Quality of photos, titles, and descriptions | Medium (room for improvement) |
| BSR (Bestseller Rank) | ★★★★☆ | Position in the category ranking | < 500 in subcategory |
Analyzing sales speed and BSR
Sales speed is the most important criterion when comparing products. A product that sells 50 times per month is fundamentally different from one that sells only 3 times per month. With the Zoloo Product Tracker, you can track and compare the sales speed of any product on bol.com in real-time.
The BSR (Bestseller Rank) indicates how well a product sells compared to other products in the same category. A lower BSR means more sales. Note: the BSR fluctuates daily, so look at the average over at least 14 days.
Calculating profit margin correctly
When comparing products, it's crucial to calculate the actual profit margin - not just the difference between the purchase price and selling price. Use the Zoloo Winstcalculator to include all costs:
- Purchase price (including shipping costs to your warehouse)
- Bol.com commission (varies per category: 5% to 17%)
- Shipping costs to the customer (or LVB costs)
- Return costs (average return percentage × costs per return)
- Packaging materials
- BTW payment
Step-by-step product comparison on bol.com
Follow this structured process to effectively compare products and make the best choices:
Step 1: Select product categories
Start by choosing 2 to 3 categories you want to research. Use the Zoloo Product Database to make an initial selection based on sales volume and number of sellers. Focus on categories with a healthy balance between demand and supply.
Step 2: Create a shortlist
Create a shortlist of 5 to 10 potential products per category. Filter by:
- Selling price between €20 and €80 (optimal margin zone)
- At least 20 sales per month
- Maximum 8 active sellers
- No brand protection or exclusive distribution rights
Step 3: In-depth comparison
Compare the products on your shortlist based on all the criteria in the table above. Create a spreadsheet or use the Zoloo Product Tracker to keep all data organized. Score each product on a scale of 1 to 5 per criterion and calculate a weighted total score.
Step 4: Competitor analysis
Analyze the existing sellers of your top candidates. Check their listings, pricing strategy, and reviews. Poor listings from competitors are an opportunity: if you create better product photos, titles, and descriptions, you can quickly create a superior listing with the Zoloo Listing Generator AI.
Step 5: Test order and validation
Order a sample of your top 2 to 3 products. Check the product quality, packaging, and delivery time. Compare the actual products with the online photos and descriptions. This prevents surprises with your first real stock.

Common Mistakes When Comparing Products
Many beginning sellers make the same mistakes when comparing and selecting products. Avoid these pitfalls:
Focusing Only on Price
A low-priced product may seem attractive, but if the margin after all costs is only €1.50, you'll earn almost nothing. Always calculate the full profit margin including commission, shipping, and returns. The Zoloo Sales Dashboard helps you keep an eye on your actual margins.
Underestimating Seasonal Products
A product that sells 200 times per month in December but only 5 times in March can be misleading if you only look at the top month. Always compare sales data over a period of at least 6 months to recognize seasonal patterns.
Ignoring Return Rate
Certain categories (such as clothing, shoes, and electronics) have return rates of up to 30%. Each return costs you money in shipping, processing, and potential depreciation. Always factor in the average return rate of the category in your comparison.
Starting Too Many Products at Once
Start with a maximum of 3 to 5 products. This gives you room to manage each product well, optimize your listings, and adjust your strategy based on the first results.
Advanced Comparison Strategies
Bundle Strategy Comparison
Don't just compare individual products, but also possible bundles. A set of 3 kitchen accessories with a higher combined value can provide a better margin than each product separately. Analyze with the Zoloo Product Database which products are often bought together.
Private Label vs. Wholesale Products
When comparing products, it's essential to understand the difference between wholesale products (reselling existing brands) and private label (your own brand). Private label offers higher margins but requires more investment in branding, packaging, and marketing.
Comparing International Sourcing
Compare purchase prices from different suppliers: Alibaba, European wholesalers, and local suppliers. Consider minimum order quantities (MOQ), delivery times, and quality differences. A product that's €2 cheaper from a Chinese supplier might be less attractive due to higher shipping costs and longer delivery times.

Frequently asked questions about comparing products on bol.com
How many products should I compare before making a choice?
Compare at least 10 to 15 products within your chosen category. Then, create a shortlist of 3 to 5 products that score best on the comparison criteria. This gives you enough data to make an informed decision.
How often should I update my product analysis?
Perform a comparison analysis at least once a month. Markets are constantly shifting: new competitors, price changes, and seasonal influences can affect the profitability of your products. With the Zoloo Product Tracker, you automate a large part of this monitoring.
Can I compare products without paid tools?
You can manually compare products via the bol.com platform itself, but this takes much more time and provides less accurate data. Tools like Zoloo offer automated sales data, trend analysis, and margin calculations that reduce manual work from hours to minutes.
What is the ideal price segment for products on bol.com?
Products between €20 and €80 offer the best balance between sufficient margin and acceptable purchase amount for customers. Products under €15 have too little margin after bol.com commission and shipping costs. Products over €100 have lower purchase volume and higher return risk.
