Last updated: May 26, 2026
The paid advertising system on eMAG that allows sellers to promote their products in search results and category pages, for a fee. It works on a CPC (cost-per-click) model — you only pay when a user clicks on your ad.
A badge automatically awarded by eMAG to products with the highest sales in a category over a recent period. The "Bestseller" badge increases visibility and buyer trust, positively influencing conversion rate.
The main "Add to Cart" button on the product page that determines which seller receives the order when multiple sellers offer the same product. Winning the Buy Box depends on price, seller rating, stock and delivery time.
The process of adjusting algorithmic estimates based on real market data to increase the accuracy of scores and indicators. In Zeff Scout, calibration is performed continuously based on aggregated marketplace data.
The hierarchical classification structure for products on eMAG, organized across multiple levels (from main categories to subcategories). Choosing the correct category directly influences product visibility and the applicable commission.
The percentage retained by eMAG from the selling price of each product sold through the marketplace, varying by category. Typical commissions range between 5% and 25%, and sellers must factor them into their profit margin calculations.
The percentage of visitors who complete a purchase out of the total who viewed a product or page. A good conversion rate on eMAG varies by category, but generally above 3-5% is considered strong performance.
The percentage of users who click on a product from the results list, relative to the total number of impressions. A high CTR indicates an attractive title, price and image relative to the competition.
The unique tax code of a company, issued by ANAF upon registration, required for registering as a seller on eMAG marketplace. Each seller must have a valid CUI associated with their seller account.
The international barcode that uniquely identifies a product globally, consisting of 13 digits. On eMAG, the EAN code is essential for matching products between sellers and for correct listing on the shared product page.
The eMAG subscription program offering free and fast delivery to buyers, similar to Amazon Prime. Genius-eligible products have a distinctive badge and benefit from increased visibility in search results.
The eMAG platform where third-party sellers list and sell products to buyers, alongside eMAG's own offers. The marketplace allows any company with a valid CUI in Romania to become a seller and access the eMAG customer base.
The service through which eMAG stores, packages and delivers the seller's products from its own warehouses, for an additional fee. FBE products benefit from faster delivery, Genius eligibility and favored Buy Box placement.
The complete process of storing, packaging and delivering products to the end buyer, from order receipt to doorstep delivery. Sellers can handle fulfillment themselves (FBS — Fulfilled by Seller) or use FBE.
The search term used by buyers on eMAG to find relevant products. Optimizing the product title and description with relevant keywords is essential for organic visibility.
A product page published on eMAG, including title, description, images, price and technical specifications. An optimized listing with complete information and quality images significantly increases conversion chances.
The difference between the selling price and the total cost of the product, including purchase price, eMAG commissions, shipping and VAT. Accurate margin calculation is critical for marketplace profitability — Zeff Scout offers a dedicated Profit Calculator.
An online market where multiple sellers list and sell products on the same platform, benefiting from the host platform's traffic and infrastructure. The most well-known marketplaces in Romania are eMAG, Altex and OLX.
Abbreviation for Marketplace, frequently used in internal communications among sellers and in eMAG documentation. For example, "MKP seller" means a third-party marketplace seller.
The National Trade Register Office, the institution where all companies in Romania are registered. ONRC data is verified by eMAG when approving seller accounts.
The position a product holds in unpaid search results on eMAG, determined algorithmically. Organic position depends on title relevance, recent sales, rating, competitive pricing and listing completeness.
A unique product identifier on eMAG, used internally by the platform to differentiate each listing. The PNK appears in the product URL and is used by Zeff Scout for tracking and analysis.
The price suggested by the manufacturer (MSRP) as a reference for retail sale of a product. On eMAG, displaying the recommended price alongside the current price can highlight a discount and increase offer attractiveness.
The process of researching and analyzing products to identify profitable sales opportunities on the marketplace. Zeff Scout offers a dedicated Product Research module with advanced filters, sales estimates and opportunity scores.
The product ranking within an eMAG category, determined by the platform's algorithm based on multiple factors such as sales, rating, price and relevance. A higher ranking means greater visibility and, consequently, more sales.
The average score given by buyers to a product or seller, on a scale from 1 to 5 stars. A high rating (above 4.5) positively influences Buy Box placement, organic position and potential buyer trust.
Written feedback left by a buyer after purchasing and using a product from eMAG. Authentic reviews are an important factor in the buying decision and influence eMAG's ranking algorithm.
Return on Investment, calculated as the ratio between profit earned and the amount invested, expressed as a percentage. For example, if you invest 1000 RON in stock and earn 1500 RON from sales (minus costs), the ROI is 50%.
A natural or legal person who sells products on eMAG marketplace, with an active seller account. Each seller has a public profile (seller storefront) and is evaluated through ratings and reviews from buyers.
The seller's unique internal code for identifying and managing each product in stock. The SKU differs from the PNK (eMAG code) and EAN (international code) — it is the seller's own code.
