Zoloo Extension: The Complete Chrome Guide (2026)

The Zoloo extensie is a powerful Chrome browser extension specially developed for bol.com sellers. With this extension you can directly analyze product data on bol.com, view search volumes and investigate competitors - without leaving the page. In this comprehensive guide we explain everything about the Zoloo extensie: from installation and features to practical tips to get the most out of it for your bol.com business.

What is the Zoloo extensie?

The Zoloo extensie is a Chrome browser extension that integrates directly with bol.com. Once you have installed the extension, extra data panels and insights appear while you browse bol.com. You see, for example, estimated revenue figures, search volumes, competition information and profit margins - right on the pages where you need them. This makes the Zoloo Chrome Extensie an indispensable tool for product research and competition analysis.

Unlike standalone dashboards where you have to switch back and forth between tabs, the Zoloo extensie works as an overlay on top of bol.com itself. This saves you time and makes your workflow considerably more efficient. The extensie is available for all Zoloo subscriptions and is regularly updated with new features and improvements.

Step 2: Click "Add to Chrome"

Step 4: Navigate to bol.com

Go to bol.com and you’ll immediately see the Zoloo overlay appear on products and search results. The extension automatically detects which page you’re on and shows the relevant data.

Step 5: Adjust your settings

Through the Zoloo icon you can choose which data panels you want to see. Some sellers want all data at once, while others prefer a more minimal view. The choice is yours.

Product research with the Zoloo extension

One of the most powerful uses of the Zoloo extension is product research. Instead of manually gathering data about products, you get all the information you need instantly while browsing bol.com.

Product Research on product pages

When you view a product page on bol.com, the Zoloo extension automatically displays a data panel with essential information. You see the estimated monthly revenue, the number of sellers, the average price and the number of reviews. This data helps you assess in seconds whether a product is interesting to sell.

Additionally, with one click you can add the product to your Product Tracker to monitor the sales pattern over a longer period. This is especially useful for seasonal products or products where you want to follow the trend before purchasing.

Category analysis in search results

On the bol.com search results page the extension shows an overview of the entire category. You see the total search volume, the average price in the category, the number of competitors and the revenue distribution among the top sellers. This information is crucial to determine whether a niche is profitable enough to enter.

Comparison with manual research

Without the Zoloo extension you would have to navigate to the Zoloo dashboard for each product, enter the EAN or title and wait for the results. With the extension you save on average 5-10 minutes per product - researching 50 products a day saves you hours of work.

Advanced features and tips

Beyond the basic functions, the Zoloo extension offers various advanced capabilities that further optimise your workflow.

Keyboard shortcuts and productivity

The extension supports shortcuts that let you quickly open or hide data. For example, press Alt+B to open or close the Zoloo panel. This is especially handy when you’re scrolling through many products and don’t want to click with the mouse each time.

Export function

Found a list of interesting products? With the export function you can export product data to a spreadsheet. This is ideal for sellers who want to document their product research or discuss it with business partners.

Integration with Zoloo dashboard

The extension is seamlessly integrated with the full Zoloo dashboard. Products you add via the extension to your Product Tracker appear instantly in your dashboard. The same applies to keywords you save through the Keyword Verkenner integration in the extension.

Automatic updates

The extension updates automatically via the Chrome Web Store. You don’t need to install anything manually - once a new version is available, it is downloaded and activated on the next browser start.

Frequently asked problems and solutions

While the Zoloo extension usually works flawlessly, occasional technical issues can arise. Here are the most common problems and their fixes:

Extension shows no data

If the extension shows no data on bol.com, check that you are logged into your Zoloo account via the extension icon. Also verify that you have an active Zoloo subscription. Try refreshing the page (Ctrl+Shift+R) to perform a hard refresh.

Extension conflicts with other extensions

In rare cases the Zoloo extension can conflict with other Chrome extensions, especially ad-blockers or other bol.com tools. Try temporarily disabling other extensions to see if the issue resolves. You can do this via chrome://extensions.

Data seems inaccurate

The data in the extension is based on estimates and historical trends. Small deviations are normal. For the most up-to-date and detailed data you can always consult the full Zoloo Sales Dashboard. The extension gives a good indication, but for strategic decisions the dashboard is more complete.

How the Zoloo extension improves your bol.com strategy

The real value of the Zoloo extension is not only in individual features, but in how it improves your entire workflow as a seller. Below we discuss the strategic benefits.

Find profitable products faster

By showing product data directly on bol.com, the extension drastically shortens your product research cycle. Instead of spending hours on manual research you spend minutes per product. This means you can evaluate more products and react faster to trends and seasonal opportunities.

Better purchasing decisions

With real-time insight into estimated revenue, competition and margins you make better-informed purchasing decisions. The Winstcalculator integration in the extension prevents you from buying products whose margin becomes too low after all bol.com costs are deducted.

Competition always in view

The extension shows how many sellers offer a product, who holds the buy-box and how the reviews are distributed. This helps you avoid markets where competition is too fierce, or spot opportunities where the buy-box is easy to win.

SEO optimisation for your listings

With the keyword data the extension displays, you can optimise your listings for the search terms buyers actually use. This improves your organic visibility on bol.com and reduces your reliance on paid ads via Sponsored Products.

Pricing and availability

The Zoloo extension is included with all Zoloo subscriptions. You don’t need a separate subscription or extra payment to use the extension. Once you have a Zoloo account, you can install the extension and start right away.

Best practices: how to get the most out of the Zoloo extension

To make the most of the Zoloo extension, it’s important to follow a structured approach. Start each research session with a clear goal: are you looking for new products, analysing competitors, or improving existing listings? By working focused you extract more value from the data the extension provides.

Always combine the extension with the full Zoloo-dashboard for deep analysis. Use the extension for quick first-pass product screening and the dashboard for final decision-making. Save promising products directly via the Product Tracker integration so you don’t miss opportunities. Make it a habit to review your saved products and keywords at least weekly to spot trends and seasonal changes in time.

Frequently asked questions about the Zoloo extension

Is the Zoloo extension free?

Yes, the Zoloo extension is included for free with every Zoloo subscription. There are no extra costs or hidden fees for using the extension. You do need an active Zoloo account to log in.

Does the Zoloo extension also work on Firefox or Safari?

Currently the Zoloo extension is only available for Google Chrome and other Chromium-based browsers such as Microsoft Edge and Brave. Firefox and Safari are not supported at this time. Most bol.com sellers use Chrome, so this has become the priority.

Can I use the Zoloo extension on multiple computers?

Yes, you can install the extension on multiple computers and log in with the same Zoloo account. Your data and settings are synced via your Zoloo account. Note that simultaneous use on multiple devices depends on your subscription.

How does the extension differ from the Zoloo dashboard?

The extension is designed for quick product research while you browse bol.com. The Zoloo-dashboard provides deeper analyses, reports and tools such as the AI Listing Generator, Automatische Facturatie and E-mail Campagnes. The extension and the dashboard complement each other: use the extension for quick scans and the dashboard for strategic analysis.

Does the Zoloo extension slow down my browser?

The Zoloo extension is optimized for minimal impact on browser performance. The extension is only active when you browse bol.com and uses efficient caching to keep the load low. If you still experience performance issues, check that you are using the latest version of Chrome and that you don’t have too many extensions active at the same time.
