1. What is Heureka and why is it important for online stores?#

Heureka is the largest shopping comparison site in the Czech Republic and Slovakia, helping customers compare offers from different online stores by price, availability, rating, and other parameters. For online stores it’s an important sales channel – not only thanks to direct traffic, but also because of the ability to collect reviews and build trustworthiness.

For working with pricing, what’s most important is the Heureka Cart, comparing offers on product cards, and bidding, with which you can influence your position among competitors.

✅ Pricing Fox supports both the Czech and Slovak versions of Heureka, and lets you use the available data for competitor monitoring as well as automating price strategies.

2. How do I connect Heureka to Pricing Fox?#

the number of competitors and the extent of the price range,
product performance statistics (if you have the API key for the new conversion measurement filled in).

Data is always obtained for a specific store and a specific language version of Heureka (CZ or SK), according to the connection chosen in Keychain.

7. What conditions must products meet for Pricing Fox to be able to compare them on Heureka?#

For Pricing Fox to correctly compare products on Heureka, the following conditions must be met:

Products must be paired on Heureka – meaning they must be visible to users on Heureka.cz or Heureka.sk.
Correctly filled-in product cards – it’s important to have correctly filled-in product information, such as name, price, availability, and category.
Sending the ITEM_ID element – in the product feed you need to send the ITEM_ID element, which matches the Product ID in the Pricing Fox settings. This lets us correctly pair products and download their data via the API.
Active PPC mode and sufficient credit on Heureka – for the connection to the Heureka API to work correctly, you need to have active PPC mode and sufficient credit on Heureka, which enables products to be displayed in the comparison.

✅ Once products are paired and correctly linked, Pricing Fox starts downloading competitor data and you can start working with price strategies.

If some products aren’t being compared, check whether you have the ITEM_ID pairing element set correctly, whether the product is paired on Heureka, and whether you have active PPC mode with sufficient credit.

8. How often is data from Heureka updated in Pricing Fox?#

Data from Heureka is updated regularly in Pricing Fox to ensure the information about competitor prices and product availability is current.

Competitor offers – are updated several times a day, which lets you track changes in competitor prices throughout the day.
Product performance statistics – are downloaded once a day, always for the previous day, and give you an overview of your products’ performance on Heureka.

✅ This regular update lets you respond effectively to price changes and optimize your price strategy.

If you have any questions about the update frequency or specific requirements, don’t hesitate to contact our support team.

9. I don’t see competitor offers for some products. Why?#

If you don’t see competitor offers for some products, there can be several reasons:

The product isn’t paired on Heureka – If the product isn’t correctly paired on Heureka, we can’t download its competitor offers.
The product isn’t available in the competitors’ offer – If the competition doesn’t sell the given product, there’s no competition available for comparison.
An error while downloading data – It can happen that during the last data update there was a problem downloading information about this product. In that case, we recommend checking the link and possibly running an update manually.
Insufficient credit on Heureka or inactive PPC mode – It’s important to make sure you have sufficient credit for active PPC mode on Heureka. If credit runs out or PPC mode isn’t active, products may not be displayed correctly and their competitor offers won’t appear.

✅ If you don’t see competitor offers for some products, we recommend checking their pairing on Heureka and making sure you have active PPC mode with sufficient credit.

If the problem persists, contact our support team for more detailed diagnostics.

10. Can I set a strategy according to my position on Heureka?#

Yes, a product’s position on Heureka.cz is one of the key factors that Pricing Fox uses to set a price strategy. When downloading data from the Heureka API, we obtain not only your product’s position on the card, but also the competitors’ positions and their offers. In addition, we track other factors, such as:

Competitor prices
Product availability
Delivery price
Store rating
Store verification (Verified by Customers)

Based on this information, Pricing Fox lets you set a reference price that you can use to reprice your product. This price strategy lets you be competitive, while you can target a specific position on Heureka or optimize your pricing policy based on the criteria mentioned above.

✅ Thanks to this data, you have the option to flexibly set a price strategy that helps you achieve the desired results on Heureka.cz/sk.
