Marketplace Management
Be visible on the marketplace and grow sales.
Marketplace store management is the service that runs your store on Trendyol, Hepsiburada, Amazon and similar platforms end to end across listing, ads, campaigns and pricing, and grows sales with a controlled ad spend. Rebel Co. Group is not an agency that opens the store and leaves, it is a digital marketing business partner that sees the real profit of every product and runs ads to an ACOS target. Working with 300+ brands across 15 sectors in 7 years, we look at profit, not at the sales screen.
Short answer: Marketplace store management is the service that professionally runs the listing, ads, campaigns and pricing of your store on platforms such as Trendyol, Hepsiburada and Amazon. The aim is to raise visibility and sales profitably by controlling ad spend with an ACOS target.
Why professional management?
Opening a store is easy, selling at a profit takes management.
Marketplace competition heats up every year. Trendyol alone holds around 45 percent of the value share of retail e-commerce in Turkey, and more than 250,000 sellers on the platform fight for a place in the rankings. In this crowd, opening a store and leaving it, keeping ads on until the budget ends and listing with weak visuals means spending money and not selling. Professional management is about getting more profitable sales out of the same budget.
- In heavy competition your products do not make the first page of search results.
- Ads stay on, ACOS grows out of control and the profit goes to ad spend.
- The listing title, visual and content are weak, so it gets clicked but does not sell.
- You miss the campaign calendar and the competitor uses discounts and points better.
Service scope
We run every layer of the store in one place.
Marketplace management is not one job, it is a setup in which six jobs feed each other. If one is missing, the return of the others leaks away. We run all of them with the same team on a single roadmap.
Store Setup and Catalogue
We set up your store with the right category, brand approval and payment setup, and organise your catalogue with variants, barcodes and attribute fields complete. A clean catalogue is the ground for every piece of work that follows.
Listing and Product SEO
We optimise the product title, attributes and description to the platform's search algorithm and to customer language. The right keyword, the right category and filled attribute fields carry you to the top of the search results.
Advertising and ACOS Management
We set up sponsored product and bid campaigns to a target ACOS and optimise them day by day. We move budget to the winning keyword and cut the searches that waste it. The aim is not to finish the budget but to grow profitable sales.
Campaign and Pricing Strategy
We plan the platform's campaign calendar in advance and shape discount, coupon and points mechanics to protect profit. For every product we calculate real profit including commission, ads and shipping, and weed out sales at a loss.
Content and Visuals
We produce product photography, infographics and showcase visuals that work for sales. The right visual raises click through rate and clear copy raises conversion. A weak visual throws away the money of a good ad.
Reporting and Analysis
Every month we put your revenue, profit, ACOS, conversion and store score on one dashboard. We show clearly which product wins and which eats budget, and base next month's plan on numbers.
How we work
It starts with an audit and returns as growth.
-
01
Store Audit
We review your current listings, your ad account, your ACOS, your pricing setup and your store score, and work out the sales you lose and the spend that goes to waste. The first audit is free.
-
02
Optimisation
We fix the catalogue, titles, attribute fields and visuals and set up product SEO. We make sure the ground is ready for sales before opening ads.
-
03
Ad Management
We set up campaigns to a target ACOS and optimise them daily. We move budget to the winning search, cut the losing one and use the campaign calendar while protecting profit.
-
04
Growth and Reporting
We report profit, ACOS and conversion every month, multiply the winning product and pattern, and scale to a new marketplace or category.
What we deliver
Not management, measurable output.
When you give us your store, you take over a system, not a screen. The return of every piece of work is visible in the report and every decision rests on a number. The outputs below are with you from the first month of the contract.
- An ad structure built to a target ACOS
- SEO friendly listings with filled attributes
- Real profit calculation by product
- A planned campaign and pricing calendar
- Product visuals and content that work for sales
- A monthly report focused on profit and ACOS
Where the difference is
Self management and agency management.
Anyone can open a marketplace panel. The difference is the method behind the panel. The table below shows how the two approaches separate with the same budget.
| Topic | Self management | Agency management |
|---|---|---|
| Advertising | Open until the budget ends, ACOS not tracked | Optimised daily to the target ACOS |
| Listing | Title and attributes filled in incompletely | Product SEO and filled attribute fields |
| Pricing | Set by guesswork, looking at competitors | Profit calculation including commission, ads and shipping |
| Campaigns | The calendar is missed, discounts are given defenceless | Planned in advance, shaped to protect profit |
| Measurement | Looks at the sales screen, profit unclear | Profit and ACOS report by product |
| Time | Buried in operations, no time for strategy | You focus on the product, we focus on growth |
Should you run the marketplace together with your own site, and which should you start with? To settle the decision, see our marketplace or own website comparison and our article on the benefits of opening your own online store.
Frequently asked questions
about marketplace management.
Which marketplaces do you manage?
In Turkey we manage Trendyol, Hepsiburada, N11, Çiçeksepeti and PttAVM, and for sales abroad we manage Amazon stores. For most brands we focus not on a single marketplace but on the two or three most profitable channels. Your product category and target audience decide which marketplace comes first, and we settle this together in the first audit.
What is ACOS and what should it be?
ACOS (Advertising Cost of Sale) shows what percentage of the sales coming from ads you spend on advertising. It is calculated as ad spend divided by ad revenue. The sector average is around 30 percent, and 10 to 25 percent is targeted for established campaigns. The right ACOS depends on your product margin: if your margin is 35 percent, break-even ACOS is 35 percent, below it you profit and above it you lose. We set a target ACOS per channel based on the balance between growth and profitability.
What costs are there besides marketplace commission?
Besides commission there is the ad budget, shipping and return costs, campaign discounts, service fees and product packaging expenses. If you build pricing without seeing these, you sell but you do not earn. For every product we build a pricing model that calculates real profit including commission, ads and shipping, and we weed out products sold at a loss. To lower returns we also apply the methods in our guide on reducing the e-commerce return rate.
Why do I need marketplace management when I already have my own e-commerce site?
The two are not rivals, they are two channels that feed each other. A marketplace brings fast sales and brand awareness with its ready traffic, and your own site brings higher margin and customer data. A healthy setup usually runs both together. If you want to see which one comes first for you, read our marketplace or own website comparison, and we combine the two channels in one strategy.
How soon will I see results?
The effect of listing and ad fixes starts to show in the first weeks, and healthy, sustainable growth usually settles in within 2 to 4 months. Your product margin, the intensity of competition, your store score and your stock position affect the time. Be cautious with agencies that promise exact figures and dates. Every month we put measured results in front of you and multiply the winning pattern.
Do you also look after stock and orders in store management?
The management scope covers the marketing and sales side: listing, ads, campaigns, pricing and content. The stock, shipping and customer service operation is usually run by you or your integration software. We work in line with that operation and reflect stock and price signals in campaign decisions. We draw the scope together in the first meeting.
How much does marketplace store management cost?
The price varies with the number of marketplaces managed, the product and variant volume, the ad budget and the intensity of competition, so we work on a quote basis. In the free store audit we map your current position, the sales you lose and the ad spend that goes to waste, and settle the scope and the quote on that basis.
Growing on a marketplace takes completeness
Marketplace sales means good ads, good listings, the right price, the right visual and steady measurement all working at once. If one is missing, the return of the others leaks: a strong ad pays for a weak visual, and a good visual sells at a loss at the wrong price. That is why we run your store not in pieces but in one place on a single roadmap. If you want to grow the same discipline on your own site, see our web and e-commerce agency service, and to raise conversion see our article on e-commerce conversion rate optimisation.
