Copying a Bestseller Is Not a Product Strategy

By Arnold Ji, Co-Founder of SKDK SPORT

By the time every seller is copying a bestseller, its advantage is already shrinking.

Same product. Similar listings. Similar keywords.

Competition eventually moves to price, advertising spend, and review count.

Following a bestseller can help validate demand. But it does not build product development capability.

What Successful Products Actually Share

Successful products are rarely random, although there is no guaranteed formula. They usually align several factors:

• A clear customer problem
• A specific use case
• Meaningful product differentiation
• A workable retail price and landed cost
• A product that is easy to understand online
• Consistent quality and repeatable supply

For e-commerce sellers, real control begins when they can understand why a product sells, identify what customers still dislike, and develop a better solution.

That creates more control over positioning, margin, and the future product roadmap.

Moving Beyond Picking an Existing SKU

At SKDK SPORT, we help customers move beyond simply selecting an existing SKU. Depending on the project, we can work together to:

• Define the target user and use case
• Review recurring customer feedback
• Improve structure, material, fit, or functionality
• Develop and test samples
• Plan branding, packaging, and bulk production

This approach applies across knee supports, ankle braces, wrist wraps, and other sports protection products where small improvements in material or fit can create real differentiation.

Why a Repeatable Process Beats Copying

Not every new product will become a bestseller.

But a repeatable product-development process gives sellers a stronger foundation than copying after the market is already crowded.

For Your Next Launch

Would you rather follow proven demand, or improve a problem existing products have not solved?
