How do I join the Media Expert Marketplace? Two-step verification 

Unlike open platforms, where almost any business can set up an account, Media Expert uses a model selective partner selection. 

Warning from a bTOP expert: „Getting onto the Media Expert platform depends, first and foremost, on whether the platform’s commercial team is willing to accept a particular seller into its ecosystem. The key criterion is to verify whether the product range aligns with the network’s strategy and whether the product categories you sell are even appropriate for this platform.” – explains Marketplace Specialist at bTOP. 

The selection process, step by step: 

1. Submission of the application form: The first step is to complete the official application form for sellers (available via Media Expert Marketplace Seller Form). 

2. Classification by category: Media Expert’s Category Managers analyse the structure of your portfolio. They look for unique brands, stable stock levels and complementary categories (e.g. Home and Garden, Sport and Leisure, Tools, Toys, Baby, Health and Wellbeing, or Household Appliances/Electronics). 

3. Decision and signing of the contract: Only once the proposal and operational indicators have been successfully verified does the company gain access to the dashboard and dedicated integrations. 

 

Strong Google search engine optimisation (SEO) as the main driver of growth 

Why do retailers apply for approval on Media Expert, even if they have their own online shops? The answer is the domain and its strong search engine authority. 

A bTOP specialist highlights the SEO benefits: „One of the biggest advantages of joining the Media Expert Marketplace is the opportunity to capitalise on their immense search engine ranking power on Google. The mediaexpert.pl domain boasts incredibly high Domain Authority scores and enjoys the trust of Google’s algorithms. When you add your product to their catalogue, it stands a chance of appearing on the first page of search results for very difficult, highly competitive keywords much faster than if you were optimising your own shop. For many brands, this is invaluable, free, large-scale product promotion.”. 

Title structure and category selection – Media Expert’s golden rules 

Media Expert’s search algorithms and UX (User Experience) policy impose specific standards on sales staff regarding the presentation of offers. 

  1. Concise and short names for offers

Media Expert focuses on simplicity. The customer should know straight away what kind of product they are dealing with. 

  • The first words in the title are key: The first 2–3 words must, without exception, describe the physical product (e.g. Built-in oven, Electric scooter, Cordless screwdriver). 
  • No keyword „stuffing”: It is prohibited to use advertising slogans such as „Hit of the season”, „Bestseller” or „Special offer”, or to overuse embellishments and capital letters. 
  1. Careful selection of categories

Incorrectly assigning an offer to a category tree in Media Expert will result in the product file being rejected at the validation stage or a drastic drop in visibility. Please note that each category may also have a different commission rate assigned to it. 

 

Costs, charges and commission structure 

The financial model on Media Expert is very transparent, which makes it easier to calculate the margin accurately before joining the platform. 

Summary of costs according to the bTOP expert: „Media Expert’s fee structure is among the most attractive and competitive on the Polish marketplace. A low, fixed monthly fee, combined with a commission-based model calculated only on products actually sold, allows you to scale your business safely without excessive fixed costs.” 

  1. Fixed monthly subscription fee
  • The platform charges a nominal fee of 49 zł gross per month. 
  • The subscription fee is fixed and does not depend on the volume of offers posted or the number of orders processed. 
  1. Sales commission (Success Fee)
  • The commission is calculated based solely on the value of completed transactions. 
  • The commission rate is determined on a case-by-case basis, based on category trees, in which the product in question is located. 
  • Depending on the product range (e.g. consumer electronics, household appliances and audio/video equipment, Home and Garden, Sport, Toys), commission rates usually vary from approximately 5% to 18%. 

How do I start selling and get my shop up and running? 

Passing the verification process is the first step. The second is to integrate stock levels and price lists efficiently. 

1. Official help centre: You’ll find a comprehensive step-by-step guide and technical details in the dedicated section How to start selling on the Media Expert platform. 

2. Integration via API / PIM: To avoid delays in dispatch, it is best to send stock levels and product descriptions via recognised integration providers (e.g. Base, Sellasist) that are synchronised with your ERP system. 

 

Summary 

Media Expert Marketplace is a prestigious sales channel that guarantees excellent reach to millions of Polish consumers and powerful support for product ranking on Google.
