Concept
A comparison shopping website, sometimes called a price comparison website, price analysis tool, comparison shopping agent, shopbot, aggregator or comparison shopping engine, is a vertical search engine that shoppers use to filter and compare products based on price, features, reviews and other criteria. Most comparison shopping sites aggregate product listings from many different retailers but do not directly sell products themselves, instead earning money from affiliate marketing agreements. In the United Kingdom, these services made between £780m and £950m in revenue in 2005. Hence, E-commerce accounted for an 18.2 percent share of total business turnover in the United Kingdom in 2012. Online sales already account for 13% of the total UK economy, and its expected to increase to 15% by 2017. There is a huge contribution of comparison shopping websites in the expansion of the current E-commerce industry. The first widely recognized comparison-shopping agent was BargainFinder, developed by Andersen Consulting (now Accenture). The team, led by researcher Bruce Krulwich, created BargainFinder in 1995 as an experiment and published it on-line without advance warning to the e-commerce sites being compared. The first commercial shopping agent, called Jango, was produced by Netbot, a Seattle startup company founded by University of Washington professors Oren Etzioni and Daniel S. Weld; Netbot was acquired by the Excite portal in late 1997. Junglee, a Bay-area startup, also pioneered comparison shopping technology and was soon acquired by Amazon.com. Other early comparison shopping agents included pricewatch.com and killerapp.com. NexTag another entry into comparison shopping was named Times magazine world top 50 website in 2008, only to eventually close in 2018. In 2005, PriceGrabber was acquired by Experian for $485 million, negotiated by then-CEO and founder of the company, Kamran Pourzanjani, along with Tamim Mourad, in 1999. Around 2010, the price comparison websites found their way to emerging markets.
