E-commerce Guides

E-commerce (electronic commerce) is the buying and selling of products and services over the internet. Sales can happen on a brand's own website, on marketplaces such as Amazon or Trendyol, or through social media channels. There are different models depending on who sells to whom: business to consumer (B2C), business to business (B2B) and consumer to consumer (C2C). Payment, delivery and customer communication are also part of the process.

To build an e-commerce website, you first decide what you will sell and through which channels, then choose a platform that fits those needs. Next come the domain, a payment provider and shipping agreements; products are added with photos and descriptions, and the legal pages are prepared. Before launch, the order, payment and return flows should be tested end to end and analytics should be set up.

An e-commerce platform is the software that runs an online store: the product catalog, cart, checkout, order and stock management and the admin panel are all part of it. There are three main options: hosted (SaaS) platforms paid for monthly, open source solutions you run on your own server, and custom software built for the business. The right choice depends on catalog size, integration needs and growth plans.

Marketplace integration is the automatic syncing of product, stock, price and order data between your own system and marketplaces such as Amazon, eBay or Trendyol. When a product sells on one channel, its stock drops on the others too, and orders are managed from a single panel. The integration is built on the marketplace APIs, either with off-the-shelf integration software or through custom development.

E-commerce SEO is the technical and content work that helps category and product pages rank well in search results. The core steps are writing a unique description for each product, keeping duplicate URLs created by filters and sorting under control, adding product structured data, improving page speed and building meaningful internal links between categories. How to handle pages for out-of-stock products should also be planned from the start.

E-commerce security is the set of measures that protect customer data, payment details and the store itself against attacks. The core measures are using HTTPS across the whole site, leaving card data to a PCI DSS compliant payment provider instead of storing it on your own servers, enabling 3D Secure, adding two-factor authentication to the admin panel and keeping the software up to date. Obligations under data protection laws such as the GDPR or Turkey's KVKK are part of it too.
