Major B2B marketplaces do have traffic, but they also have clear structural limitations: intense price competition, homogeneous information, making it hard for buyers to differentiate you from competitors, and most importantly—transaction data remains outside your control. According to yStats.com's global trend report, as many as 50% of global buyers prefer purchasing on "manufacturer-owned proprietary platforms," because they get first-hand, most accurate information and build direct trust with the original manufacturer. A more practical strategy is: use major marketplaces for traffic generation, but simultaneously build your own proprietary digital portal where formal trading workflows, customized quotations, and order history remain in your system. This allows you to accumulate first-hand customer data that belongs to you, rather than remaining forever dependent on platforms.
