Case Study: Biocodex achieves a 38% U.S. Amazon market share increase with Similarweb Shopper Intelligence

How Biocodex increased its Amazon market share by 40% with Similarweb Shopper Intelligence

Biocodex, the maker of Florastor probiotics, saw growing U.S. revenue from eCommerce—mostly on Amazon—but lacked visibility into its Amazon market share and competitor performance. Without a reliable market view they couldn’t tell if sales growth meant share gains, which made budget and growth decisions difficult.

By combining internal sales data with Similarweb Shopper Intelligence and producing monthly reports, the team benchmarked category and competitor performance and presented a case for added customer‑acquisition budget. As a result, increased investment drove a 38% rise in Florastor’s U.S. Amazon market share in seven months (to over 4% of the probiotics category) and gave ongoing visibility into the impact of their spend.
