As the saying goes, ‘you don’t know what you don’t know.’ In other words, marketplaces need to look beyond just their four walls to see what high-demand or best-selling items might be missing from their catalogs. By running an assortment gap analysis to find the right mix of products, marketplaces can then use Cluster data to identify the sellers of those items or categories and upload them quickly to their sites.

When it comes to finding new leads for any business, the challenge always lies within converting those leads. A cold call or email just won’t cut it anymore. By running an assortment gap analysis first, online enterprises can figure out the lowest hanging fruit first – in other words, they can first go back to their current reputable sellers and ask them to onboard new items that may be generating sales successfully on another channel. Essentially, this is a warmer lead since those sellers are already familiar with your platform. Then, by using Cluster data, customers can reach out to those top-sellers with a compelling reason so it’s hard for them to say no to joining your marketplace. With more robust data, the lead-gen process, all the way to onboarding becomes much more streamlined and all in one offering.

By leveraging APIs to find the right mix of products, enterprises can achieve more sustainable and scalable growth. By retrieving the data and being able to perform their own analysis and actions, enterprises have the flexibility to find out what products or categories work best for them (especially if they have a niche marketplace, for example DIY). By knowing what’s going on across the entire eCommerce landscape, enterprises can analyze their competition and make adjustments in real time to keep up.
