Get an instant quality score for your MALL.cz product listing. Our checker validates your title, description, images, and pricing against MALL.cz-specific rules used by the Czech marketplace.
MALL.cz is one of the largest e-commerce marketplaces in the Czech Republic, now part of the Allegro Group. With millions of Czech shoppers browsing daily, your listing quality directly determines whether your products appear in search results and whether shoppers click "add to cart." MALL.cz uses a proprietary ranking algorithm that weighs listing completeness, keyword relevance, and seller performance metrics.
Unlike Western European marketplaces, MALL.cz has strict requirements around the Czech language. Product titles and descriptions must avoid promotional superlatives like "nejlevnejsi" (cheapest) or "nejlepsi" (best), which are flagged by automated content filters. Listings that violate these rules may be demoted in search results or rejected entirely during the review process. Our checker validates your content against these Czech-specific rules before you publish.
The optimal title length on MALL.cz is between 45 and 100 characters. This range balances keyword richness with mobile display constraints. Titles shorter than 45 characters typically lack product specifics that Czech buyers search for (brand, model, color, capacity). Titles longer than 100 characters get truncated on mobile devices, which account for over 60% of MALL.cz traffic. Structure your titles as: Brand + Product Type + Key Specification + Differentiator (e.g., "Samsung Galaxy S24 Ultra 256GB Titanium cerny").
MALL.cz requires product images with a minimum resolution of 800x800 pixels on a clean white background for the main image. Additional images should showcase the product from multiple angles, demonstrate key features, and include lifestyle shots showing the product in use. Sellers with 5 or more images per listing report 30-40% higher conversion rates compared to listings with only 1-2 images. MALL.cz also supports 360-degree product views and video content for enhanced listings.
MALL.cz uses EAN/GTIN codes to match products across sellers and build unified product pages. Without a valid EAN code, your product may not be eligible for the Buy Box (the default purchase option shown to buyers). If you sell branded products, the EAN is printed on the packaging or available from the manufacturer. For private-label products, register with GS1 Czech Republic (gs1cz.org) to obtain official barcodes. Listings with valid EAN codes also benefit from automatic category assignment and improved search indexing.
When setting prices on MALL.cz, remember that Czech shoppers are highly price-sensitive and frequently compare prices across Heureka.cz, Zbozi.cz, and other comparison engines. MALL.cz displays prices in Czech Koruna (CZK), and your pricing should account for MALL.cz commission fees (typically 5-15% depending on category), shipping costs, and any DPH (VAT) obligations. Use the MALL.cz Fee Calculator to model your margins before listing.
