Key Takeaways

Actowiz monitored 20,000–30,000 product listings across three European marketplaces — Amazon.de, Kaufland.de, and Allegro.pl — with daily updates. For each listing it captured product name, brand, category, product ID, price, discount, availability, delivery information, seller name, rating, review count, and product URL. Beyond a daily snapshot, the pipeline tracked change signals: new products appearing, price and availability changes, and products disappearing from the marketplaces. Delivered as CSV/Excel/Sheets (API-ready later) with a modular per-marketplace design, the client could start with one marketplace and add the others as budget allowed.

What did the client need?

The client needed to monitor product data across three European marketplaces — Amazon.de, Kaufland.de, and Allegro.pl — for an estimated 20,000–30,000 listings, updated once a day.

They needed product names, brands, categories, product IDs, prices, discounts, availability, delivery information, seller names, ratings, review counts, and URLs — plus tracking of new products, price/availability changes, and products that disappear — with a modular design to start on one marketplace and add the others later.

What made this hard?

Three marketplaces. Amazon.de, Kaufland.de, and Allegro.pl differ structurally and had to normalize into one schema.
Change detection. New, changed, and disappeared products had to be detected across daily snapshots.
Volume at daily cadence. 20K–30K listings refreshed daily required a resilient pipeline.
Seller & rating capture. Seller names, ratings, and review counts added marketplace-specific complexity.
Modular scaling. The client wanted to start with one marketplace and add others by budget.

How did Actowiz solve it?

Actowiz built modular per-marketplace pipelines into one normalized schema, with daily change detection.

Approach

Per-marketplace pipelines. Amazon.de, Kaufland.de, Allegro.pl normalized into one schema.
Daily refresh. Full daily update across all monitored listings.
Change detection. New, changed, and disappeared products flagged across snapshots.
Full attribute capture. Price, discount, availability, delivery, seller, rating, reviews, URL.
Modular scaling. Start with one marketplace; add others without rework.

Client Feedback

“We wanted three European marketplaces watched daily — prices, sellers, and what's new or gone — but with the option to start on Amazon.de and add the rest. Actowiz built it modular, exactly that way.”
