The .ECOM domain zone is a top-level domain (TLD) that was proposed in 2014 as an alternative to the .COM zone for online stores and other electronic commerce platforms. However, the .ECOM domain zone was not approved and never made it to the operational stage. There are other domain zones that can be used for e-commerce, such as .shop, .store, .market, .online, and others. However, .com remains the most popular and widely used domain zone for commercial websites worldwide, and many businesses choose it for their online stores and other electronic platforms.
