How to Create a Website Like eBay?

Here are the key steps you need to follow to create a website like eBay:

1. Conducting Market Research

To build a strong foundation for your e-commerce business like eBay, conducting market research proves to be very promising. Without market research, you might not have enough insights on how to start a business like Bay.

As per numerous sources such as Forbes and Huff Post, 90% of e-commerce businesses fail within their first 120 days of operation. 

Therefore, market research is curial to find the right niche and products to sell.

After all, you indeed don’t want to waste your efforts on creating an e-commerce platform to discover no one is interested in what you’re selling.

When it comes to conducting market research for building a website like eBay, you need to focus on the following key aspects:

  • e-Commerce Industry Overview: The current and future state of the e-commerce marketplace industry to gauge its profitability before entering into it.
  • Identify & Understand Your Target Audience: Gain a solid understanding of the audience you want to target and their needs. This will help you know does your target audience needs and/or wants what you’re planning to sell. If not, then you can then scrutinize your business plan once again.
