What is Walmart Marketplace, and What Key Metrics Do I Need to Track?

Understanding and leveraging eCommerce platforms like Walmart Marketplace has become crucial for brands across various sectors. As online shopping rates continue to grow, so does the data available to marketers who use them.

Retail marketplace APIs provide brands with a powerful opportunity to understand customers' shopping behavior directly through eCommerce channels. 

The Walmart Marketplace API, provided by the retail giant Walmart, has emerged as a game-changer, offering marketers a direct channel to assess their sales performance with Walmart's vast online marketplace.

In this blog we’ll take a look at how marketers can get the most out of their Walmart Marketplace data, and which metrics they need to track in order to measure the success of their marketing efforts.

What is Walmart Marketplace?

Walmart Marketplace is Walmart's eCommerce platform, offering third-party brands direct access to millions of online shoppers through seamless product listing, order management, and inventory synchronization. 

Marketplace sellers are given the opportunity to use as a venue to sell and promote their products on alongside Walmart’s own products.


What’s the difference between being a seller on Walmart Marketplace Vs. being a Walmart vendor?

As there’s no intermediary buyer for brands selling on Walmart Marketplace, sellers can list any items they want, provided they’re not prohibited - and they can determine their own prices.

The Marketplace boasts numerous integrations with third-party platforms, simplifying the shipping and order handling processes, which is a notable advantage over the logistics required by Walmart suppliers. The Fulfill By Walmart (FBW) program closely mirrors Amazon's FBA initiative, and the platform’s Seller Center is continuously improving.

How can I get sales data from Walmart Marketplace API integration?

By using a Walmart Marketplace API integration, brands can stream their operation performance, enhance visibility, and reach Walmart's extensive customer base more effectively.

Brands can collect insights tailored to their goals, such as product catalog management, inventory updates, order processing, and shipping integration. 

The platform not only facilitates efficient eCommerce operations but also unlocks insights into customer behavior, which can be cross-referenced to other marketing efforts. Therefore, brands are able to optimize their product offerings, pricing strategies, and overall customer experience within Walmart's vast online marketplace.


Why should Walmart Marketplace metrics matter to marketers?

Tracking key metrics on Walmart Marketplace is essential for marketers selling on the platform as it provides insights into sales performance driven by campaigns, influencing customer behavior, and overall return on investment (ROI). 

By closely monitoring these metrics, brands can make data-driven decisions, optimize their advertising strategies, and maximize their impact on Walmart's highly engaged customer base.



What Walmart Marketplace metrics should I track?
