The concept of market share is one of the most important metrics for any entrepreneur who wants to grow seriously on bol.com. Market share tells you what percentage of total sales in your product category is generated by your store. In this extensive article, we explain what market share is, how to calculate it, what the difference is with turnover, which factors influence it, and - most importantly - how you can strategically increase your market share.
What is market share exactly?
Market share (English: market share) indicates what part of the total market turnover or total sales volume is realized by your company. It is always expressed as a percentage. If the total market for phone cases on bol.com is €2 million per month and you generate €100,000 in sales, then your market share is 5%.
There are two commonly used ways to measure market share:
- Value share: based on turnover in euros - your turnover divided by the total market turnover.
- Volume share: based on the number of units sold - your sold units divided by the total number of units sold in the market.
Both metrics provide a different perspective. A seller with higher prices may have a larger value share but a smaller volume share, and vice versa.
How do you calculate market share?
The basic formula for calculating market share is simple:
Market share (%) = (Your turnover ÷ Total market turnover) × 100
Let's say you sell kitchen machines on bol.com. The total market for kitchen machines on the platform is €5 million per quarter. Your turnover in that same quarter is €250,000. Then your market share is: (250,000 ÷ 5,000,000) × 100 = 5%.
Below you will find an overview of example calculations for different categories:
| Category | Total market turnover | Your turnover | Market share |
|---|---|---|---|
| Phone cases | €2,000,000 | €100,000 | 5.0% |
| Kitchen machines | €5,000,000 | €250,000 | 5.0% |
| Toys | €8,000,000 | €640,000 | 8.0% |
| Sports nutrition | €3,500,000 | €70,000 | 2.0% |
| Gardening tools | €1,200,000 | €180,000 | 15.0% |
| Pet supplies | €4,000,000 | €320,000 | 8.0% |
| Office supplies | €2,800,000 | €84,000 | 3.0% |
| Bicycle accessories | €1,500,000 | €225,000 | 15.0% |
To calculate your own market share, you need two pieces of information: your own turnover (which you can find in the Zoloo Sales Dashboard) and an estimate of the total market turnover. Tools like the Zoloo Product Tracker help you collect market data and estimate the total market size.
Market share versus turnover: the crucial difference
Many sellers focus exclusively on their turnover, but that only gives you part of the picture. Market share is a relative measure that compares your performance to the rest of the market. Here's the difference in a nutshell:
Turnover: the absolute measure
Turnover is the total amount of sales you realize in a certain period. If your turnover increases from €50,000 to €60,000 per month, that seems positive. But if the total market in the same period grows from €1 million to €1.5 million, then your market share has decreased from 5% to 4%. You're selling more, but your competitors are growing faster.
Market share: the relative measure
Market share puts your sales into context. It tells you if you're growing faster or slower than the market. An increasing market share with a steady sales volume means the market is shrinking, but you're outperforming your competitors. A decreasing market share with increasing sales volume means your competitors are growing faster.
When to focus on what?
- Focus on sales volume when you're working on profitability, cash flow, and operational costs.
- Focus on market share when you want to evaluate your strategic position, make investment decisions, or assess your competitive strength.
- Monitor both is essential for a complete picture of your business performance as a bol.com seller.
Factors that influence your market share
There are dozens of factors that determine how big your slice of the pie is. The most important ones for bol.com sellers are:
1. Product range and assortment
The broader and more relevant your product range, the more buyers you'll attract. Use the Zoloo Product Database to identify gaps in the market and strategically expand your product range.
2. Price and buy block
On bol.com, a lot depends on winning the buy block. A competitive price is one of the most important factors. Use the Zoloo Ranking Checker to see how your prices compare to the competition.
3. Visibility and SEO
You can have the best product at the best price - if no one finds it, you won't sell anything. Optimize your listings with relevant keywords using the Zoloo Keyword Verkenner. Read more about SEO on bol.com.

5. Logistics and delivery time

Strategies to increase your market share
Now that you understand what market share is and what factors influence it, here are concrete strategies to strengthen your position:
Strategy 1: Niche focus
Instead of having a small share in a huge category, focus on a specific niche where you can dominate. A market share of 25% in a niche worth €500,000 is more valuable (and achievable) than 0.5% in a market worth €50 million.
Strategy 2: Data-driven product research
Use product research tools to spot trends, recognize seasonal patterns, and discover product opportunities before your competitors do. Whoever serves a growing segment first will capture the largest market share.
Strategy 3: Listing optimization
Improve your product titles, bullet points, descriptions, and images with the Zoloo Listing Generator AI. Optimized listings convert better, which directly leads to a higher market share.
Strategy 4: Pricing strategy
Continuously monitor your competitors' prices. Sometimes, a small price reduction is enough to win the buy box. Always calculate your profit margin before adjusting prices, so you don't sell below your cost price.
Strategy 5: Optimize Customer Experience
Offer excellent customer service with tools like the Zoloo Customer Support AI. Fast, personalized answers lead to better reviews, more repeat purchases, and a growing market share.
Monitor and Measure Market Share
Regularly monitoring your market share is essential to know if your strategies are working. Here are the best methods:
- Sales Dashboard: View your daily and monthly sales in the Zoloo Sales Dashboard and compare them to market trends.
- Product Tracking: Follow your competitors and the total market size with the Zoloo Product Tracker.
- Trend Analysis: Use historical data to recognize seasonal patterns and adjust your strategy accordingly.
- Benchmarking: Compare your market share per product category, per season, and per region to identify improvement opportunities.
Common Mistakes in Market Share
Sellers often make mistakes when interpreting and pursuing market share. Avoid these pitfalls:
- Focusing only on sales growth: Rising sales can mask a declining market share if the market is growing faster.
- Defining the market too broadly: If you define your market too broadly, your market share will seem smaller than it is. Focus on your specific niche or subcategory.
- Pursuing market share at the expense of profitability: A larger market share is worthless if you're operating at a loss. Always calculate your profit margin.
- Ignoring competitors: If you don't monitor your competitors, you'll miss signals that they're gaining ground. Use tracking tools to keep an eye on the market.
- Not taking action: Data without action is worthless. Translate your market share insights into concrete improvement plans.
Frequently Asked Questions about Market Share
What is a good market share on bol.com?
This varies greatly per category. In a niche market, 15-25% can be excellent, while in broad categories, 2-5% can represent a strong position. What matters is that your market share is stable or growing.
How often should I measure my market share?
Measure your market share at least monthly. During peak periods (holidays, Black Friday), weekly monitoring is recommended. With Zoloo, you can have this done automatically daily.
Can my market share increase while my sales decrease?
Yes, this can happen. If the total market shrinks (due to seasonal effects) and your sales decrease less than those of your competitors, your relative market share will increase despite a declining absolute sales figure.
What is the difference between market share and share of voice?
Share of voice measures your visibility in the market (how much of the search results, ads, or content is yours), while market share measures your actual sales performance. Both are important: share of voice is often a predictor of future market share.
