Sellers on marketplaces typically want several key things to maximize their success and profitability. These include:

1. Increased Sales: Sellers want to generate more sales to grow their business and increase their revenue. They seek marketplaces that have a large customer base and high traffic to ensure maximum exposure for their products. For example, Amazon is a popular marketplace that attracts millions of customers daily, providing sellers with a vast potential customer base.

2. Competitive Pricing: Sellers aim to offer competitive prices to attract customers and stand out among their competitors. They want to ensure their pricing strategy allows them to make a profit while remaining attractive to customers. Marketplaces often provide tools and data to help sellers analyze market trends and set optimal prices. eBay, for instance, offers a feature called "Terapeak" that provides sellers with insights on pricing and demand trends.

3. Efficient Order Management: Sellers want streamlined and efficient order management processes to ensure smooth operations. They seek marketplaces that offer user-friendly interfaces, automated order processing, and integration with their existing systems (e.g., inventory management software, shipping providers). Etsy, a popular marketplace for handmade and vintage products, offers integrated shipping labels and order management tools to simplify the process for sellers.

4. Marketing and Promotion Opportunities: Sellers desire marketing and promotion opportunities to increase their product visibility and reach a wider audience. They look for marketplaces that offer advertising options, sponsored product placements, and targeted marketing campaigns. For instance, Walmart Marketplace provides sellers with advertising options like Sponsored Products and Display Ads to boost their product visibility.

5. Seller Support and Resources: Sellers appreciate marketplaces that offer dedicated support and resources to help them succeed. They seek platforms with responsive customer service, educational resources, and seller forums or communities where they can seek advice and share experiences. Amazon provides various resources like Seller University, Seller Support, and Seller Forums to assist sellers in navigating their platform effectively.

6. Trust and Security: Sellers want to operate on marketplaces that prioritize trust and security. They seek platforms that have robust fraud prevention measures, secure payment gateways, and policies to protect against counterfeit products or buyer scams. eBay, for example, offers seller protection programs and a feedback system that helps build trust between buyers and sellers.

7. Data and Analytics: Sellers value access to data and analytics that provide insights into their performance, customer behavior, and market trends. They want marketplaces that offer comprehensive analytics tools, sales reports, and performance metrics to help them make informed business decisions. Google Shopping, for instance, provides sellers with detailed performance reports and insights through its Merchant Center.

Overall, sellers on marketplaces want a combination of increased sales, competitive pricing, efficient operations, marketing opportunities, support, trust, and access to data and analytics. These factors collectively contribute to their success and profitability on the platform.
