Crex Data Scraping - Solving Accuracy and Data Consistency Issues in Cricket Analytics

Introduction

In Germany, many shoppers check idealo before buying. In France, Cdiscount is one of the largest online marketplaces. For brands selling in both countries, these two sites show where their products are priced lowest, by whom, and with what delivery costs.

idealo and Cdiscount price monitoring means collecting, on a schedule, the offers listed for your products on idealo's price-comparison pages and on Cdiscount's marketplace: each retailer or seller, price, shipping cost, availability and delivery time. Brands use it to spot aggressive discounting, check channel consistency and understand how their products are positioned in two of Europe's biggest markets. For the wider German picture beyond idealo, see our Amazon.de and Otto marketplace Germany coverage and our German eCommerce pricing trends from Otto and Zalando analysis.

Why these two sites matter

idealo aggregates offers from many online shops for the same product, so it shows the full spread of retailer prices in one place – and the lowest price shoppers see first.
Cdiscount is a large French marketplace where many third-party sellers compete on the same product, often with frequent price changes.

Together they give a brand a clear picture of retailer and reseller pricing in Germany and France, beyond Amazon.

What to track

Field	idealo	Cdiscount
Product match	Product page or EAN	Product page or EAN
Offers	All listed shops and prices	All sellers and prices
Lowest price	Lowest offer and shop	Featured offer and seller
Shipping	Shipping cost shown per shop	Delivery cost and time
Availability	In stock / delivery time	In stock / delivery time
Seller type	Retailer name	Cdiscount or marketplace seller
Ratings	Shop / product ratings where shown	Seller and product ratings

Also capture total price (price + shipping), because the cheapest product price is not always the cheapest total.

How to set up monitoring

Step 1 – Match products

Use EAN / GTIN where available, then model numbers and titles. Keep a master list of your SKUs and their idealo and Cdiscount pages.

Step 2 – Collect offers

Collect all offers per product daily for key SKUs and weekly for the long tail. Increase frequency around Black Friday and seasonal sales.

Step 3 – Calculate metrics

Lowest total price, number of offers, price spread, and gap to your recommended retail price.

Step 4 – Alert and report

Alert on new lowest prices far below your RRP, new sellers, and stock-outs at key retailers. The downstream enforcement workflow for authorised-seller and price-policy cases is covered in our MAP monitoring services.

Metrics brands use

Pricing law basics in the EU

In the EU, brands can set recommended resale prices, but fixing minimum resale prices is generally restricted under competition law (see the vertical block exemption, Regulation (EU) 2022/720, and its guidelines). Price monitoring is a normal market-intelligence activity, but how a brand uses the data with retailers must follow competition law. Take legal advice for your situation. Our EU MAP vs resale price maintenance guide sets out how recommended and advertised-price policies differ from prohibited price-fixing.

Legal and compliance basics for data collection

Collect only public offer information, respect each site's terms and rate limits, do not log in, and do not collect personal data.

Build vs buy

Matching products, handling many offers per page and two languages takes effort. A managed provider delivers clean offer tables for both sites in one format.
