Seller analysis, to get better insights into your competition

What is Seller analysis?

The Seller analysis shows how your offer compares to other sellers offering the same product (same EAN).

A monitor rule gives you instant insight into key information, such as:

Your current buy box status
Which seller currently holds the buy box
Buy box price and the difference compared to your own price (+ or -)
Your price compared to the lowest offer
Number of competing sellers
Seller rating
Maximum delivery time
Own stock availability

These insights help you understand your market position and take actions to improve your performance.

Why use the Seller analysis?

By understanding how your offer compares, you make smarter decisions about:

Pricing: adjust your price to stay competitive or to win the buy box
Shipping: improve delivery times to match or beat competitors
Stock: ensure availability when others are out of stock
Strategy: identify when it’s smart to go for the buy box or when to hold back

Seller analysis helps you manage your offer strategy instead of guessing. You’ll react faster to market changes and gain more control over your performance.

Create a new seller analysis monitor rule

You can easily create a monitor rule in the Seller analysis. This enables you to automatically track how your offer is performing compared to the competition.

After you’ve created a monitor rule, it may take up to an hour for all data to be fully processed. The cronjob refreshes the data automatically every hour.

Overview seller analysis monitor rule

Go to Reports > Seller Analysis > select the desired monitor rule for analysis.

Here you’ll find an overview of your buy box allocation, based on seller, scenario, and offer distribution.

This overview always reflects the most up-to-date snapshot: every time you open the rule, you instantly see the latest data.

Products
In the ‘Products’ tab, you’ll find an overview of the products within your selected product range and which seller currently holds the buy box for each product, including their price.

Filters you can set:

Sellers
In the ‘Sellers’ tab, you’ll see an overview of all vendors offering the same products.

Use this data to:

Fine-tune your repricing rules
Adjust your shipping settings
Optimize your stock management

💡Tip: Get the most out of the seller analysis by combining it with the repricer.

Practical example

You’re selling a power drill on Bol.com but notice you’re not winning the buy box.
seller analysis shows that your price is €2 higher than the current buy box holder and your delivery time is one day longer.

You now know exactly what to adjust: lower your price where possible and improve your delivery time, keeping your offer competitive without unnecessarily losing margin.

💡Tip: are you using the repricer? Set your minimum selling price (MSRP) to instantly check if your pricing strategy aligns with the current buy box price.

If your minimum price doesn’t match, you can decide whether to adjust it or reconsider the product’s place in your assortment.

You can also create additional rules, for example, by brand or only for products in stock, to focus your analysis on specific brands or segments. If you hold the buy box for many items and are also the lowest-priced seller, consider whether you can increase your prices because being the absolute cheapest isn’t always necessary to remain visible.
