Such specialized portals are price comparison portals or portals with product tests. Beyond these two types there are portals that are built up as direc-tories, in which online shops are listed by product categories.At the price comparison portals or portals with product tests, the online shops are in the back-ground. Because the main purpose of these portals is the comparison of prices and product reviews. But precisely these portals offer information about online shops. E.g. which payment options can be used, which delivery options are available, which features a shop has and who the provider of an online shop is.Customers of online shops can often contribute by making ratings of the shops.enB2CE-CommerceE-Shop330 - Wirtschaft005 - Computer Programmierung, Programme und Daten05 - Forschungs- oder Arbeitsbericht
