The Zoloo Extension is an essential Chrome browser extension for every serious bol.com seller. With this tool you get instant access to product data, keyword analyses, competition information and profit calculations - all from your browser while you surf bol.com. In this comprehensive article you’ll read everything about the Zoloo Extension, from installation to advanced use, and discover why thousands of sellers use this extension daily.
What is the Zoloo Extension?
The Zoloo Extension is a Chrome browser extension specially developed for sellers on bol.com. The extension integrates directly with the bol.com website and displays relevant sales data, market information and competition analyses on top of the existing bol.com pages. This means you don’t need to open a separate dashboard - all information appears directly in your browser while you view products on bol.com.
The extension is part of the Zoloo platform and works seamlessly with other Zoloo tools such as the Zoloo Dashboard, the Product Tracker and the Keyword Verkenner. This lets you switch quickly between fast analyses via the extension and deep research via the dashboard.
Zoloo Extension features and capabilities
The Zoloo Extension offers a wide range of features that help you as a bol.com seller make better decisions. Below you’ll find an overview of the most important capabilities.
Product data on bol.com pages
When you visit a product page on bol.com, the Zoloo Extension immediately shows relevant sales data. You’ll see estimated monthly sales, the number of sellers, price history and the category ranking of the product. This information helps you quickly assess whether a product is interesting to sell.
Keyword analysis and rankings
The extension provides insight into the keywords a product is found for. You can see which search terms a product ranks for, the search volume of those terms, and how the competition looks. This is essential for optimizing your listings and finding new product opportunities via the Ranking Checker.
Competition analysis
With the Zoloo Extension you can instantly see who your competitors are for a specific product. The extension shows the number of active sellers, their prices, shipping methods and reviews. This lets you gauge how hard it is to win a spot in the buying block.
Profit calculation
One of the most valuable features is the built-in winstcalculator. Directly from the product page you can enter your purchase price and see what your net profit would be after deducting bol.com commissions, shipping costs and btw. This prevents you from buying products that turn out to be unprofitable.
Category overview
When you view a category page on bol.com, the extension shows extra data about the whole category. You’ll see total market volume, the average number of sellers per product, the average price and the distribution of reviews. This helps identify lucrative niches.

Comparison: Zoloo Extension vs. other bol.com tools
There are several tools available for bol.com sellers. What makes the Zoloo Extension unique compared to alternatives? Below we compare the key aspects.
Integrated experience
Unlike standalone dashboards, the Zoloo Extension works directly inside the bol.com website. You don’t have to switch between tabs or separate applications. All data appears as an overlay on the page you’re viewing, making the research process much faster and more intuitive.
Data accuracy
Zoloo collects data from millions of products on bol.com and updates it daily. Sales figures, rankings and keyword data are based on extensive collection and advanced algorithms. This lets you trust the information presented when making purchasing decisions.
Full ecosystem
The extension is not standalone. As part of the Zoloo platform you have access to the full ecosystem: the Product Database for deep product research, the AI Listing Generator for optimized product titles and descriptions, the Sales Dashboard for revenue analysis, and the E-mail Campagnes tool for customer communication.
Pricing model
Zoloo uses a transparent pricing model where the Chrome extension is included with every subscription. There are no hidden fees or extra charges for using the extension. This is unlike some competitors that offer the extension as a separate paid add-on.

Practical use cases for the Zoloo Extension
The Zoloo Extension is valuable in many situations. Below we discuss the most common use cases that sellers use the extension for daily.
Product research and sourcing
When you are looking for new products to sell, the extension is your best friend. Browse categories on bol.com and the extension instantly shows for each product the estimated sales, number of competitors and profit margin. This lets you screen dozens of products in minutes without ever leaving bol.com. Combine this with the Product Tracker to monitor promising products over time.
Listing optimization
The keyword data from the extension is essential for optimizing your product listings. You can see which keywords successful competitors rank for and use that information to improve your own titles, bullet points and descriptions. The AI Listing Generator can further help by automatically generating optimized content.
Determine pricing strategy
With the price history and competitor data shown by the extension, you can develop a well-grounded pricing strategy. You see what prices competitors use, how the price has changed over time, and what the optimal price is to win the buy box without sacrificing margin.
Niche analysis
By exploring categories with the extension active, you can quickly assess which niches have potential. The extension shows aggregated data per category: average number of sellers, average sale price, total estimated volume, and the demand-supply ratio. This is an excellent way to discover new growth opportunities.
Seasonal analysis
The extension also helps you identify seasonal products. By looking at sales trends over multiple months, you can spot patterns and adjust your inventory in time. This prevents overstock after the season or too little stock during peak periods.
Margin optimization and purchasing decisions
A often underestimated advantage of the Zoloo Extension is the ability to perform real-time margin calculations while you view products from suppliers or wholesalers. By keeping the extension open and comparing purchase prices at the same time, you can instantly see which products deliver the best profit margins. This not only saves time but also prevents costly mistakes when buying large quantities. Experienced sellers also use the extension to evaluate their existing assortment: products that fall below a certain margin can be identified and possibly removed to make room for more profitable alternatives.
Tips for getting the most out of the Zoloo Extension
To get the most out of the Zoloo Extension, there are several best practices that experienced sellers apply.
Combine extension with dashboard
Use the extension for quick scans and first impressions, but switch to the Zoloo Dashboard for in-depth analysis. The extension is perfect for screening products; the dashboard provides the details you need for a well-informed decision.
Keep a shortlist
When you find interesting products through the extension, save them directly to your Product Tracker. This builds a shortlist of potential items you can monitor over a few weeks before making a purchasing decision.
Analyze your competition regularly
Don’t use the extension only for discovering new products; also use it to keep an eye on your existing competition. Regularly check the product pages of your top sellers to see if new competitors appear, prices change, or rankings shift.
Check multiple categories
Don’t limit yourself to a single category. The power of the extension is that it makes it easy to quickly browse different categories. Some of the best opportunities lie in niches you wouldn’t normally look at.
