Heureka.cz Product Search Scraper: Extract Product Listings at Scale

---

What Is Heureka.cz?

Heureka.cz (and its Slovak counterpart Heureka.sk) is one of Central Europe's largest price comparison platforms, aggregating millions of products across hundreds of categories — from electronics and appliances to fashion and sports gear. It consolidates offers from hundreds of e-shops, making it a valuable source for pricing intelligence and market analysis.

Manually collecting this data is impractical at scale. The Heureka.cz Product Search Scraper automates extraction from any category or filtered search page, delivering structured records ready for analysis.

Overview

This scraper targets Heureka product search and category listing pages, extracting rich product-level data including pricing ranges, review metrics, variant counts, and price drop signals. It is built for:

• E-commerce analysts monitoring competitor pricing and assortment
• Price intelligence teams tracking market trends across categories
• Product managers benchmarking their catalog against the market
• Developers building price comparison or deal-detection tools

Input Format

{
  "urls": [
    "https://mobilni-telefony.heureka.cz/?f=2"
  ],
  "offset": 20,
  "ignore_url_failures": true,
  "max_items_per_url": 200
}

Field	Type	Description
urls	array	URLs of Heureka product search or category listing pages to scrape. Add one per line or use bulk edit. Example: https://mobilni-telefony.heureka.cz/?f=2
max_items_per_url	integer	Maximum number of products to collect per URL. Default: 20. Increase for larger datasets.
offset	integer	Number of items to skip before collecting. Useful for paginating through results or resuming a partial run.
ignore_url_failures	boolean	If true, the scraper continues when a URL fails instead of stopping the entire run. Recommended for bulk scraping.

Tip: Heureka supports rich filter parameters in URLs (e.g., ?f=2 for in-stock items). Apply filters directly in the URL before pasting into the input for more targeted results.

How to Use

1. Find your target URL — Navigate to a Heureka category or filtered search page and copy the full URL.
2. Apply filters in the URL — Use Heureka's on-site filters (brand, price range, availability) before copying; the URL will encode your filters.
3. Configure the input — Paste URLs into urls, set max_items_per_url based on category size, and use offset to skip already-collected items.
4. Run and export — Start the scraper and download results as JSON, CSV, or Excel.

Best practices:

• Set ignore_url_failures: true for multi-URL runs to avoid interruptions.
• Use offset to collect in batches if a category has thousands of products.
• Cross-reference Shop Count and Offer Count to gauge product competitiveness.

Use Cases & Business Value

• Price monitoring: Track Min Price and Max Price fluctuations over time for key products
• Deal detection: Use Price Drop fields to surface discounts automatically
• Assortment analysis: Map competitor catalogs by category using Category Name and Variants Total Count
