eBay is an online auction website that connects buyers and sellers within B2C and C2C sectors. It means that the marketplace provides entrepreneurs and sellers with an opportunity to place their goods and buyers to purchase them online.

The platform has two possible pricing models: fixed price and auction. The first one is widespread and works as on any online store.

When the auction is over, vendors sell the product to the highest bidder.

What are the pros and cons of auction websites like eBay?

Before building a website like eBay, you need to know the strengths and weaknesses of similar multi-vendor marketplace development platforms. This knowledge will help you stand out from other marketplace rivals and get customers interested, especially sellers. It’s them who evaluate your platform rules and guidelines and decide whether to join your platform or not.

So, let’s take a look at the advantages and disadvantages of websites like eBay for users.

Pros of eBay for users

  • Target a huge audience

The core benefit of selling on eBay is its high traffic. For the past 10 years, the number of active users has increased dramatically. In the second quarter of 2019, the amount was equal to 182 million active users.

This fact makes starting an online marketplace a beneficial solution for both sellers and platform owners. It works the following way: vendors can provide tons of products and target a huge audience of potential customers. When buyers start purchasing goods, sellers pay different commissions and fees that go to marketplace owners. This way, it becomes a beneficial mechanism for both website vendors and entrepreneurs.

  • Get support as a new seller

To launch a store, a new seller can read the valuable guidelines for starting a successful eBay business. eBay offers different community features like discussion boards and question and answer (Q&A) forums. This way, they can get important knowledge from the vendors who have already succeeded on the marketplace.

  • Get loyal customers

If sellers are interested in growing their profit on the marketplace, they will definitely try to offer a perfect buying experience for customers to get loyal clients. This can be reached by providing high-quality goods, fast delivery and shipping, and giving repeated customers certain bonuses. Put it simply, once made a sale, sellers have good prospects to get repeat buyers by providing an excellent service or high product quality.

This way, it becomes a win-win strategy for both parties: sellers want to stand out from the crowd and provide high-quality products due to high competition that generates more profit for the marketplace.

  • Sell Anything

One of the advantageous features of auction websites like eBay is the all-in-one approach: is the all-in-one approach: vendors can sell and buy everything. Regardless of the niche, sellers can definitely find any specific audience.

It is beneficial for both a marketplace owner and users: buyers can find any product and purchase it, thus allowing the platform to get more transaction fees. This way, everybody wins.

Cons of eBay for users

  • Pricing policy

When sellers create an online store on an auction website like eBay, the shop both generates new sales and charges fees. Most frequently, a fee is some amount of each sale in percentage terms. For example, vendors sell a book for $15 and they will pay from $0.5 to $1.5 seller fee to the platform.

Below you can see the table of basic fees for most categories on eBay.

  • Limited layout opportunities

The platform offers sellers to create a personal online store layout with an ability to manage the position of different elements. However, there are still many restrictions in manipulating the layout structure and elements’ positioning. This is explained by the fact that most websites like eBay are interested in promoting the products, not the sellers. For this reason, pretty much the features are preliminary determined and restricted in managing by the website.

  • Shipping speed affects store visibility

The platform rewards those sellers who are able to ship the item on the same day or the following one. In case vendors face certain challenges with shipping, their online store visibility will be decreased.

  • High competition

eBay has millions of users willing to sell their products so vendors will definitely face a huge competition. To overcome this issue, they need to offer a unique product, cut down prices, or avoid listing some categories at all. Anyway, sellers should find out a strategy to stand out from the crowd.

To conclude, websites like eBay have both benefits and drawbacks. You need to consider all of them and come up with the optimal balance to satisfy all the platform parties.

What should be your first steps?

Now let’s see what questions you need to consider before starting to build a website like eBay.

1. Find your specific niche to overcome huge competition

The rivalry in the marketplace domain is pretty high. It may become rather complicated to succeed in developing an all-in-one platform with a wide range of products and services nowadays. The matter is that such e-commerce juggernauts as eBay, Amazon, Etsy, AliExpress, and others have already occupied many market segments and try to leave behind any competitors.

There is a more efficient way to start your business. Choose a specific niche initially to narrow your focus and stand out from the competitors in the market. For example, pick an untouched sphere and try to make your platform unique. This way, you will have more prospects after the platform launch.

2. Choose the optimal business model

Come up with the way you will earn money on the platform. Depending on the type (vertical/horizontal), participants (C2C, B2C, C2B, B2B), and niche (goods, services, information, investment/fundraising), you can choose a particular monetization model.

Now let’s take a look at the main revenue sources you need to take into account.

  • Commission

When a buyer pays to a seller, the platform receives a percentage or a fixed amount of the total sum amount.

  • Membership fee

This revenue option is quite good when you provide high value to the customers. For example, you can offer customers a wider range of vendors to have more product options.

  • Listing fee

This monetization tool allows you to charge sellers for each listing.

  • Lead fee

It is a seller-oriented revenue model with the following flow: buyers place requests and vendors pay a fee to bid on these consumers.

  • Featured listings and ads

It is one of the most popular models for service providers. This way, they get more visibility for their classifieds thus generating more profit. General listing is completely free, but in case sellers want to get featured, you can offer different types of posting: the top ad of a category or posted on the marketplace homepage, etc.

3. Come up with an idea of solving the chicken and egg problem

Who to acquire first: consumers or providers? Is it reasonable to target the sides one after another or is it more beneficial to invite them simultaneously? There are multiple solutions and all of them deserve your attention. Let’s take a look at the most efficient techniques briefly:

  1. Acquire the hardest side first
  2. Fix attention on a particular market
  3. Stimulate the most essential platform party
  4. Arrange astounding live action
  5. Tie up a deal with a celebrity
  6. Take up a producer’s position
  7. Set a time or demand constraint.

Make it as simple as possible. Try to avoid multiple dropdowns and nested lists when you are building a website like eBay. The easier it is to find a “Buy Now” button, the more purchases are made. Users tend to evade complex logic and too many clicks. Build a comprehensive user journey to make clients happy while browsing your auction website.

Trust and security

Credibility is the key to success. Create trust-based relations with users and you will have more chances to get loyal customers in the long run.

User involvement
