How does an E-commerce Agency like ZDA work?

As a unique e-commerce agency Z Digital builds e-commerce websites that convert and last. The process typically starts with a strategic planning phase, where the scope and objectives of the e-commerce project are defined. From there, the agency undertakes tasks spanning design. Once validated, starts the web development, and technical tracking set up, as well as e-commerce marketing optimizations to ensure a successful launch and sustained growth. This includes creating a user-friendly design, developing robust functionality, implementing effective SEO strategies, all with CLEAN CODE, and optimized website speed.

What Are the Steps of Building an E-commerce Website?

Building an e-commerce website involves several critical steps:

  1. Planning and Strategy: Defining the target audience, business objectives, and requirements for the online store.
  2. Design: Crafting a visually appealing and intuitive user interface that enhances the shopping experience and reflects the brand.
  3. Development: Constructing the backend systems (easier when working with Prestashop, Shopify or Woocommerce) and integrating e-commerce functionalities such as shopping carts, payment gateways, and product management.
  4. Testing: Rigorously testing the website to ensure all features work correctly across different devices and platforms.
  5. Speed & SEO optimization: getting a 80/100 minimum lighthouse speed rating, and integrating the results of our Digital Demand Analysis (SEO research) into the e-commerce website and internal page rank build.
  6. Launch and Marketing: Going live with the website and initiating marketing efforts like PPC advertising, email marketing, and social media campaigns to attract and retain customers.
  7. Maintenance and Optimization: Ongoing support to resolve issues, update content, and continuously optimize the site for search engines and user experience.

What Are the Critical Elements When Building an E-commerce Website?

When building an e-commerce website, several elements are critical for its success:

  • User Experience (UX): Ensuring the site is easy to navigate and pleasant to use, which helps reduce bounce rates and increases conversions. Z Digital Agency has now 10+ years of experience on most e-commerce CMS.
  • Mobile Optimization: Creating a responsive design that works seamlessly on mobile devices, crucial given the increasing trend of mobile shopping.
  • Security: Implementing robust security measures, including SSL certificates, secure payment gateways, and compliance with data protection regulations to protect customer information (GDPR/nLPD)
  • SEO and Content: Optimizing content for search engines to improve visibility and crafting engaging product descriptions and imagery that drive sales. This requires a Digital Demand Analysis & preproduction SEO audits (one of ZDA specialities)
  • Scalability: Building the website with scalable solutions that can grow with the business, accommodating more products or higher traffic without performance issues. We build a lot with AWS, but are flexible with other hosting provider, and even offer our owned managed hosting.
  • Large inventories: making sure your inventories and complex warehousing processes are coherent, easy to use and compliant.
  • Tracking: e-commerce optimization requires tracking, with Google Tag Manager, GA4, server-side tracking and proper consent management (aka cookies popups)
