⚡ Quick answer: Marketplaces like Prom.ua and Rozetka give you instant access to built-in traffic and shoppers who are already searching for your product, but they take a cut of your revenue through fees and leave you with little control over your brand or SEO. Your own WooCommerce store requires you to solve the traffic problem yourself, but it’s fully yours — no per-sale commission and no dependence on a platform’s rules. Prom.ua and Rozetka rank among Ukraine’s most-visited e-commerce destinations (according to SimilarWeb), so for most product categories the optimal strategy isn’t choosing one over the other — it’s running both channels at once.
Picture the owner of a small home-goods store who started selling on Prom.ua two years ago. The first orders came within a week — the marketplace brought shoppers in on its own, with no need to build an advertising funnel from zero. But two years later, revenue has plateaued, the commission and catalog-boost fees are eating a growing share of the margin, and to the buyer the brand is just “another seller on Prom,” with no loyalty or recognition attached. Now the owner is wondering whether to launch a dedicated online store, and whether doing so means giving up a sales channel that’s actually working. The right answer is both — and this article explains why.
Prom.ua and Rozetka (through Rozetka Marketplace) are essentially storefronts with built-in traffic, where the seller pays for access to already-formed demand instead of building that demand from scratch.
Prom.ua and Rozetka use different monetization models: Prom.ua traditionally runs on a subscription-plan model plus pay-per-click in some promotion formats, while Rozetka Marketplace charges a commission on every sold item, with the rate varying by category. Either way, a share of every sale goes to the platform, and that share doesn’t shrink as volume grows — in absolute terms, it only grows.
A marketplace’s main advantage is that buyers are already on the platform, searching through internal search or browsing categories. You don’t have to convince someone to visit an unfamiliar website at all — they’re already on a Prom.ua or Rozetka they trust, and ready to compare offers. For a new business without its own brand recognition, this dramatically lowers the barrier to starting online sales.
The flip side of that same built-in traffic is that you’re competing on the same page with dozens of other sellers of the same product, often on price as the primary deciding factor. A marketplace structurally pushes toward price competition, because it’s easier for a buyer to compare several sellers’ prices in one click than to judge service quality or a unique value proposition.
Every rule of the game — the catalog ranking algorithm, return policies, product card formats, how you’re allowed to communicate with buyers — is set by the platform, not you. A change to the product-ranking algorithm or a fee increase can meaningfully shift your sales overnight, and you have zero say in it. In effect, you’re building a business on someone else’s land, under someone else’s rules.
WooCommerce is a WordPress plugin that turns a regular website into a full online store with a catalog, cart, payment, and shipping. Unlike a marketplace, this is your own territory.
On your own site, you control everything: design, category structure, how products are presented, loyalty programs, post-purchase email flows. The buyer interacts with your brand specifically, not with a generic marketplace where next time they’re just as likely to buy from you as from a competitor one card over.
You pay for hosting, domain, and site maintenance — fixed costs that don’t scale proportionally with revenue. On a marketplace, by contrast, the commission or promotion fee scales with your revenue, so the more you sell, the more you pay the platform in absolute terms.
Content and product pages on your own site get indexed by Google under your own domain and keep working for your brand for years — an article or category page that ranks in the top of search results keeps bringing free traffic for months and years afterward. On a marketplace, you can’t influence SEO positioning for your brand as such, since the product page belongs to the platform, not to you. We’ve covered building this kind of store in detail in “Building an online store on WordPress” and “Online store on WooCommerce”.
This is the main downside: your own site is unknown to anyone on launch day. Without ads, SEO, or social media, it simply gets no visitors. You’ve traded “competing for attention inside a marketplace” for “getting people to the site at all” — and that requires a dedicated budget and strategy, for example through SEO promotion and SMM.
| Criterion | Prom.ua / Rozetka | Your own WooCommerce store |
|---|---|---|
| Fees and listing costs | Subscription plan and/or per-sale commission depending on category — scales up with revenue | Fixed costs for hosting, domain, and maintenance, no per-sale commission |
| Traffic and visibility | Built-in traffic of shoppers already searching for the product — instant start | You have to drive traffic yourself via SEO, ads, and social media — slower start |
| Brand control | Minimal — the buyer sees the platform first, your brand second | Full — design, UX, communication, and loyalty are entirely yours |
| SEO value | Accumulates in favor of the platform’s domain, not your brand | Accumulates on your own domain and keeps working for years |
| Competition for attention | High — the buyer compares you against dozens of sellers on the same page | Low within your own site — but you must bring the buyer to you first |
| Scalability | Limited by the platform’s rules and algorithms | Unlimited — depends only on your strategy and resources |
| Setup and maintenance cost | Low barrier to entry, fast start without development | Higher upfront investment in development and ongoing SEO/ads |
Framing it as “either the marketplace or your own site” is the wrong question. In practice, the most resilient strategy for Ukrainian e-commerce is running both channels in parallel, because they solve different problems.
A marketplace gives you a fast, predictable order flow and acts as a kind of testing ground: you see which products sell best, at what price, in which season — before committing serious budget to building your own brand. At the same time, your own site builds long-term value: it accumulates SEO traffic, lets you build a customer database for email and retargeting, and crucially, it protects the business from a scenario where your only sales channel is a platform whose rules you don’t control.
There’s a financial logic to it too: high-margin products with recognizable branding are more profitable to push through your own site, where there’s no per-sale commission, while low-margin “loss-leader” products with heavy competition are often more efficient to sell through a marketplace, where built-in traffic compensates for lower margin per unit.
The main operational challenge of running both channels is avoiding accidental duplicate listings or selling something that’s already out of stock. A few approaches help:
When a business owner runs the numbers on which option is more profitable, they usually compare only the obvious figures — marketplace commission versus website development cost. But there are costs that aren’t immediately visible on either side.
Beyond the base commission or subscription fee, active sellers on Prom.ua and Rozetka often pay extra to boost their catalog ranking, highlight a product card, or join platform promotions — without which a listing gets buried among hundreds of competitors even with decent base visibility. The real “cost per sale” on a marketplace in competitive categories often ends up higher than the nominal rate if a seller wants a steady order flow rather than occasional sales.
A self-owned store needs ongoing technical upkeep: updating WooCommerce and plugins, backups, security monitoring, speed optimization as the catalog grows. That’s a recurring budget line, not a one-time development cost. On top of that, the site will almost certainly run in the red on traffic for the first several months: SEO usually takes 4-6 months of consistent work to show real results, not an instant payoff after launch. Owners expecting an immediate flow of orders like they got on a marketplace often get discouraged in the first few weeks, even though that’s a normal growth curve for any new domain.
On a marketplace, part of the buyer’s trust is effectively “borrowed” from the platform itself — Prom.ua and Rozetka already have reputations as reliable services with buyer protection. On your own site, you have to build that trust yourself: reviews, certifications, transparent shipping and return policies, clear company contact information. That’s extra work worth planning into your own store launch from day one, not leaving for “later.”
If you’re just launching a new product and want to quickly validate demand without a large development investment, starting with a marketplace makes more sense — the barrier to entry is lower, and you get your first sales and demand data within weeks. If you already have a recognizable brand, a loyal audience, or high-margin products where brand trust matters (cosmetics, niche accessories, handmade goods), investing in your own online store pays off long-term — you stop sharing margin with a platform and build an asset that’s entirely your own.
If the budget is tight and you need to quickly validate demand, it’s better to start with a marketplace — it’s cheaper and faster. Launch your own store once demand is confirmed and you have the resources to drive traffic separately.
Yes, and that’s common practice. The key is setting up inventory sync between channels to avoid a product being sold on one platform while still showing as available on the others.
Usually a marketplace, since built-in traffic compensates for a low margin through sales volume without significant customer-acquisition spend. Your own site requires separate traffic investment, which may not pay off as quickly on low-margin products.
There’s no direct negative effect, but visibility you build on a marketplace doesn’t transfer to your own domain either — they’re two separate SEO value systems, and ranking well on Prom.ua or Rozetka doesn’t add any authority to your site in Google’s eyes.
WooCommerce maintenance is mostly fixed costs for hosting and technical upkeep that don’t scale directly with revenue. Marketplace costs, by contrast, scale with sales through commission or catalog-promotion fees.
Growing marketplace sales is a strong signal that demand for the product is confirmed, and that’s exactly the right moment to launch a parallel site of your own — so you can start capturing part of that confirmed demand without the platform’s commission, while building brand value that compounds over time.
