A well-prepared listing on Trendyol is not a matter of „dropping a product in”, but of organising your catalogue so that the platform and buyers in Romania immediately understand what you are selling. Below we show how to add products on Trendyol step by step – from catalogue structure, through images and descriptions, to categories and attributes – so you avoid the most common listing rejections.

Before you start adding products, it is worth having the whole context of selling on the Romanian market in place – if you are just starting out, take a look at our guide to selling on Trendyol. Listing itself is one stage of the broader selling on Trendyol in Romania that we run operationally for clients.
Catalogue structure on Trendyol
The Trendyol catalogue is built on separating two concepts: the product (the product page with description, images and attributes) and the offer (your price, stock level and delivery terms for that product). This distinction is crucial, because it determines whether you are adding a brand-new page or attaching to an existing one.
In practice you have two paths for adding:
- Attaching to an existing page – if the product (a known brand with a barcode, for example) is already in the Trendyol catalogue, you attach your offer to the ready-made page. Faster, but you share the description and images with other sellers.
- Creating a new page – for your own products or ones not in the catalogue. You have full control over the content, but the page goes through verification before publication.
Every product is identified by a code. Most often this is a barcode (EAN / GTIN), and products with variants (size, colour) are tied together by a shared model identifier. Well-planned numbering is the foundation – if you get the codes wrong at catalogue level, untangling variants later is hard.
The methods of adding differ in scale:
| Method | When to use it | Notes |
|---|---|---|
| Panel (manual) | Single products, tests, corrections | Full control, but slow with a large catalogue |
| Excel template / bulk file | Dozens of items or more at once | Requires correct mapping of columns to attributes |
| Integration / API | Large catalogues, frequent updates | Stock and price synchronisation automatically from your system |
If you sell in several places at once, listing on Trendyol is worth treating from the outset as part of automation and synchronisation across markets, rather than as an isolated manual task.
Requirements for images and descriptions
The image is the first filter in a purchase decision and, on Trendyol, also the first filter for accepting your listing. The platform rejects photographs that do not meet its presentation standards, so it pays to stick to a few fixed rules.
Good practices for product images:
- A white / neutral background on the main image – the product clearly separated, with no unnecessary props.
- High resolution – when preparing product graphics for Trendyol RO, keep the platform’s strict guidelines in mind – ideal images have vertical 2:3 proportions at a resolution of 1200 × 1800 px and 96 DPI.
- Several shots – the main image plus additional ones (details, scale, use). The limit is 8 images per page.
- No logos, watermarks or promotional text on the image – a frequent reason for a page being rejected.
A product description has two jobs: to convince the buyer and to give the platform signals for its search engine. So write concretely – material, dimensions, use, contents of the set – rather than in generalities.
A good description on Trendyol has a repeatable structure that is easy to scale across the whole catalogue:
- A first sentence with something concrete – what it is and who it is for, with no marketing warm-up.
- Technical parameters – dimensions, material, power, capacity – preferably in the same units the category uses.
- Contents of the set and use – what the buyer gets in the parcel and what they will use it for.
- Answers to typical questions – the things that would otherwise arrive as messages to the seller or as returns.
The language of the description matters
Trendyol, in the version we handle, takes your offer to buyers in Romania. A description in Romanian (not only in English) has a real effect on visibility and conversion. A machine „word for word” translation usually is not enough – what counts is natural industry terminology and the wording a local customer searches for. It is the same mechanism we describe in selling in Romanian e-commerce.
Categories and product attributes
Choosing the category is one of the most important decisions when adding a product – it determines which attributes you will have to fill in, which filters your offer appears in and (indirectly) what commission applies to the sale. A badly chosen category can hide a good product from buyers.
Attributes fall into two groups:
- Mandatory – without them the page will not pass publication. The set depends on the category (in clothing, for example: size, colour, material, gender).
- Optional – the more of them you fill in, the better the product lands in filters and long-tail searches. Empty optional fields are lost visibility.
The practical order of work on a product page looks like this:
- Category first – match it as precisely as you can, not by rough guess.
- Then the mandatory attributes – the complete set, correctly formatted (units, values from the platform’s dictionary, not your own wording).
- Variants last – if the product comes in sizes or colours, tie them to a shared model so the buyer picks a variant on a single page.
Variants are a frequent flashpoint. If you add every size as a separate, unlinked product, you scatter reviews and visibility across several weak pages instead of one strong one. The exact set of required attributes differs by category.
The most common mistakes when adding listings
Most rejections and weak sales results do not come from a „difficult platform” but from repeatable mistakes at the listing stage. These are the ones we see most often among sellers entering the Romanian market:
- An image that does not meet the standard – a coloured background, a watermark or too low a resolution. The page goes into review and does not get published.
- The wrong category – assigning an item to an unsuitable subcategory, which makes it impossible to fill in key technical attributes and leaves the product invisible in customers’ filters.
- Gaps in mandatory attributes – the listing stays suspended until they are completed.
- Variants as separate pages – scattered reviews and a weaker position than a single page with variants.
- A description copied from another market – lifted straight from Allegro or eMAG, without Romanian terminology or local units.
- Duplicate codes / barcodes – the same identifier on different products blocks publication.
The good news is that all of these mistakes are predictable and can be caught with a checklist before the listing is even submitted. If you add products in bulk, the checklist should be built into the import template rather than checked by hand on every page.
It is also worth remembering that listing does not end on publication day. Prices, stock levels and attributes have to be maintained over time – and with a larger catalogue that is done by synchronising from your system, not by hand. That is why, for clients with a broad assortment, we set the process up from the start so that a single price or stock change reaches Trendyol automatically, with no risk of a product selling at an outdated price or going negative in the warehouse.
Frequently asked questions
How long does verification of a new product page on Trendyol take?
New pages go through a check before publication – usually counted in hours up to a few working days. The exact time depends on the category and how complete the data is. Attaching an offer to an existing page is normally faster than creating a new one.
Do I need a barcode (EAN) to add a product?
A product identifier is required, because it is what links the offer to the page and to its variants.
What language should product descriptions on Trendyol be written in?
For an offer aimed at the Romanian market, write in Romanian – it translates directly into search visibility and buyer trust. Treat English as a supplement, not as the page’s main language.
Can I add the whole catalogue at once instead of product by product?
Yes. With a larger number of items you use a bulk template (a file) or an API integration, which additionally synchronises stock and prices. Leave manual adding for single products and corrections.
How does adding products on Trendyol differ from eMAG?
The „product page plus offer” logic is similar, but the category dictionaries, required attributes and image standards are different. Starting from zero, close off Trendyol seller registration first and only then the catalogue.
