What is the difference in data tracking between an ecommerce marketplace and a singular ecommerce website?
An ecommerce marketplace is where many buyers and sellers can both shop and sell goods, so it's usually called a two-sided marketplace. eBay, Amazon, Shopee, Lazada, and Rakuten are all popular ecommerce marketplaces. There are thousands of sellers and millions of competing products in marketplaces. It is harder to track prices from marketplaces because there are protective and regulatory measures to keep crawlers out of the system to standardize both the selling and buying experience. Marketplaces also use bot protection services and have security departments to make sure external marketplace data tracking doesn't happen.
An ecommerce website usually serves buyers/consumers where a particular business or brand is behind the website as the only seller. Custom stores built with e-commerce platforms like Magento, Shopify, Woocommerce, Prestashop, or Bigcommerce are all examples. Custom-coded websites also fall into this category. Because owners of these websites control their own technology or use shared technology passed through ecommerce platforms, the security or crawlability of these pages is much easier than the marketplaces.
