Most Sellers Active on Six Marketplaces

A growing number of online sellers are distributing their products across multiple marketplaces, with new research showing that the average seller is now active on six different e-commerce platforms. This trend reflects how digital commerce is evolving, with sellers seeking to reach customers wherever they shop. The findings come from ChannelEngine’s Marketplace Seller Trends 2025 report, as summarized by EcommerceNews in October 2025.

The report surveyed 470 sellers across the United Kingdom, France, Germany, the Netherlands, and the United States to provide a comprehensive picture of current marketplace strategies. It reveals that a significant majority 67 percent of sellers operate on four or more marketplaces, highlighting a shift from traditional single-channel sales to more diversified approaches.

This shift is driven by changing consumer habits. Shoppers increasingly browse several platforms before making a purchase, encouraging sellers to maintain a presence across multiple marketplaces to capture their attention. As the report indicates, having a multi-marketplace presence is no longer a luxury but a necessity for growth and survival in the highly competitive online retail space.

However, managing sales on six platforms is far from easy. The study reveals that while 62 percent of sellers use marketplace integrators or software tools to help automate listing and inventory management, more than half of respondents still rely on spreadsheets or internal tools to handle day-to-day operations. This hybrid approach points to a transitional phase where many sellers have yet to fully embrace or implement automation solutions.

Manual tasks still dominate sellers’ weekly routines. The report shows that sellers spend an average of 36 percent of their working hours updating product listings, correcting errors, adjusting prices, and synchronizing stock levels. This significant time investment can hinder sellers’ ability to focus on strategic growth initiatives, customer engagement, or marketing efforts.

When asked about their business priorities, sellers highlighted improving sales performance on existing marketplaces as their top focus, with 32 percent aiming to increase revenues within current channels. Another 31 percent are working on boosting product visibility to stand out in crowded marketplaces, while 27 percent are focused on improving profitability. These figures, derived from ChannelEngine’s report, suggest that sellers are currently prioritizing optimization over rapid expansion.

Nevertheless, expansion remains a goal for many. The report states that 39 percent of sellers plan to add more marketplaces to their sales mix in the near future. However, economic uncertainty and technical complexity act as major obstacles, with 28 percent citing financial risks and 26 percent mentioning integration challenges as reasons to hesitate. These barriers are particularly pronounced for smaller businesses lacking specialized staff or advanced software infrastructure.

Keeping pace with evolving platform requirements also poses a significant challenge. Approximately 27 percent of sellers report difficulties adapting to frequent changes in marketplace rules, policies, and compliance standards. This issue is especially critical for sellers who continue to rely heavily on manual processes; among this group, 40 percent identify changing platform demands as their greatest operational hurdle.

Competition intensifies these challenges. Nearly 30 percent of sellers named maintaining competitive pricing and visibility as their primary struggle. As EcommerceNews reports, this reflects the crowded nature of major marketplaces such as Amazon, bol.com, and eBay, where thousands of sellers offer similar products. Success requires not only listing products but also excelling in areas like advertising, logistics, customer service, and user experience.

Despite these complexities, sellers remain committed to the multi-marketplace model. Marketplaces have become the dominant channels for consumer shopping, especially in Western markets. The report suggests that not being present on these platforms risks missing out on substantial sales opportunities.

To succeed, sellers must invest in operational efficiency. The ChannelEngine report emphasizes that businesses adopting advanced automation tools such as inventory synchronization, dynamic pricing, and error detection software—are better positioned to scale and maintain accuracy across marketplaces. EcommerceNews reinforces this view, noting that sellers who treat backend operations with strategic importance tend to outperform their peers.

Moreover, sellers call on marketplaces to improve their support systems. Many express a need for simpler onboarding processes, clearer documentation, and more intuitive interfaces, particularly when expanding internationally. These improvements could lower barriers for smaller sellers and reduce the complexity of managing multiple sales channels.

Perhaps the most profound insight from the report is a shift in mindset. Marketplaces are no longer secondary sales channels but have become primary business platforms for many sellers. This evolution changes how sellers allocate resources, approach branding, and design customer experiences.

Looking ahead, as sellers increase their presence across multiple marketplaces, competition will only intensify. EcommerceNews predicts that operational speed, logistics efficiency, and customer satisfaction will become key differentiators in an increasingly crowded market.

In summary, the Marketplace Seller Trends 2025 report and related industry coverage highlight a maturing e-commerce environment where multi-marketplace selling is the norm. Sellers who can effectively manage complexity through automation and strategic focus are best positioned for sustainable growth in a fast-changing retail landscape.
