How price comparison websites work
Price comparison websites extract essential details such as product prices, reviews, features, and descriptions from multiple sites. These details are then compiled on the price comparison website and tailored accordingly for easy access. So, when a buyer searches for a product on the website, the site quickly compares and lists similar products from a number of retailers. This process simplifies the buying decision of the buyer since they can compare factors such as price deals, shipping costs, and other features.
However, the algorithms involved depend on massive data. As expected, data extraction in real-time is not only daunting but time-consuming. As if that wasn’t enough, the dynamic pricing system employed by e-commerce websites makes it difficult to keep track of price changes. Amazon, for instance, is approximately 417 hours faster than its competitors in adapting price changes.
