All you need to know about the product research tool
The Product Research Tool on sellerrr.com helps Kaufland sellers discover which products are actually selling — and which ones aren’t. It gives users access to daily-updated data on revenue, units sold, number of sellers, reviews, and more. The tool supports multiple Kaufland marketplaces, including kaufland.de, kaufland.pl, and others.

You can filter the product database by price, star rating, number of sellers, reviews, categories, and more. Once you click on a product, you’ll get detailed historical data visualized in graphs — including weekly estimated revenue and unit sales. These insights are calculated by tracking stock availability of sellers. For example, if a product showed a quantity of 10 on Monday and 8 on Tuesday, we assume 2 units were sold.

Once you open the graph view on a product, you’ll see daily revenue data for each seller individually, as well as combined totals for all sellers. You can check exactly when tracking started, when the most recent update occurred, and when the next update is expected. It’s also visible whether an item is currently available for purchase or not. Besides revenue, units sold and units left are tracked as well.
The delivery cost shown in the graph is the average delivery fee across all offers. The product price displayed is a weighted average — calculated by taking the total number of units and their respective prices into account, resulting in a more accurate reflection of the real market price. Unlike the price, the delivery rate is not weighted; it’s simply the sum of all delivery costs divided by the number of offers. This way, you get a clear view of shipping trends without distortion.
You can also add your own products to track by simply submitting the Kaufland URL. The first data will appear after about one day, but it’s strongly recommended to wait at least 1–2 weeks before making decisions. This allows trends to emerge based on average performance rather than daily fluctuations.
Tracking is done per marketplace, and you can filter and search based on the one you’re focused on. All data — including stock levels, price changes, and competition — is automatically updated each day.
Note: if you stop tracking a product and no other user is tracking it either, the product and its data will disappear from the system after 24 hours. If you want to keep seeing historical data, make sure to keep tracking it.
In short: it’s a straightforward tool that gives you quick access to real Kaufland sales insights, letting you research faster and smarter — no guesswork, just data.
