The box that wins the main 'Add to Cart' button on a product listing on marketplaces like Trendyol and Amazon.

The vast majority of sales come from the Buy Box winner.
View details →A paid ad format on Trendyol that lets sellers show their products at the top of search results or on product pages for a bid. It runs on a cost-per-click (CPC) or task-based model. Together with conversion rate and seller score, it directly determines ad efficiency; high-converting listings achieve a lower ad share (ACOS) for the same budget.
View details →The percentage of visitors who view a product listing and add it to cart. Add-to-cart rate = add-to-carts / product-page views × 100. It measures how convincing the main image, price and title are. A high add-to-cart rate but low checkout completion means the issue is in the checkout; a low add-to-cart rate means the issue is listing quality.
View details →The percentage a marketplace charges from each sale as a service fee. On Trendyol the commission rate is set by category and calculated on the VAT-inclusive sale price. Net payout = sale price − commission − service/shipping fee. Commission directly affects net profit; break-even pricing must account for it.
View details →The system that aggregates and displays ratings customers give for purchased products and sellers. On Trendyol, product ratings and seller service scores are tracked separately. A high rating directly boosts search rankings, Buy Box probability and conversion rate. Negative reviews and low scores quickly reduce visibility; customer experience and returns management are key to maintaining ratings.
View details →A composite score marketplaces like Trendyol give to a seller's overall performance. It consists of metrics like on-time delivery, customer satisfaction, return rate and response speed. The seller score directly affects search ranking, visibility and eligibility to participate in campaigns. A low score can lead to listing restrictions or sales suspension.
View details →The suite of paid advertising solutions Trendyol offers to sellers. Main formats: Sponsored Product (visibility in search/category ranking) and Sponsored Store. Ad budgets are managed via ad share (ACOS); conversion rate and seller score determine efficiency. Unlike Google and Meta ads, the impact is limited to within the marketplace.
View details →The process covering participation in discount and pricing campaigns organized by marketplaces like Trendyol at certain periods, price adjustments and performance tracking. Good campaign management lifts revenue but can also cause margin loss through underpricing; knowing your break-even price is critical during campaign periods. Campaign ACOS (ad share) and net margin must both be tracked.
View details →The optimization of titles, tags, product attributes and descriptions so listings rank at the top of Etsy search results. Etsy's algorithm matches the buyer query with these fields, then ranks by signals like conversion rate, seller score and freshness. Filling all 13 tags with long-tail phrases aligned to buyer intent is the foundation of Etsy SEO.
View details →The section of Amazon reserved only for genuinely handmade products. Sellers go through an application and approval process and must prove products are made by hand. This selectivity limits competition. Amazon Handmade connects to Amazon's massive traffic, Prime reach and FBA logistics, giving artisans global scale; in return, the referral fee is higher than niche platforms like Etsy.
View details →Amazon's self-service publishing platform; it lets you sell books worldwide both digitally (Kindle e-books) and in print (print-on-demand). The author/publisher earns royalties on sales; for print the rate applies after print cost is deducted, while for digital it can reach ~70% depending on the price range. Low-content books are a common way to build a scalable portfolio on KDP.
View details →A book type where most of the content consists of blank or repeating pages: notebooks, planners, journals, puzzle books and sketchbooks. It is popular on Amazon KDP because an interior template designed once can be turned into dozens of titles with different niches and covers. It's one of the fastest ways to build a scalable portfolio and passive income with little production effort.
View details →A sales model where products are printed and shipped only as orders come in, requiring no stock. The seller uploads a design; a provider like Printify or Printful handles printing and shipping. It's common for products like t-shirts, mugs, posters and phone cases. The advantage is zero stock and low startup cost; the downside is the net margin squeezed after print and shipping, and quality variability that depends on the supplier.
View details →A product that requires no physical stock and is delivered electronically: templates, e-books, online courses, digital art, software and downloadable files. It's produced once and sold unlimited times; since production and delivery cost is near zero, profit margin is very high (~85%). The downside is that creating demand and trust requires content, SEO and funnel work.
