E-Commerce is a multi billion dollar industry. The retail sector of e-commerce has seen increases in sales of over 18% yearly, since 2005. Rapid growth in e-retail has been the norm and not the exception. Many traditional brick and mortar stores are switching to a brick and click model, but the lion's share of e-retailers are nonstore retailers with online stores only. The trend, then, shows us that e-commerce retailers have become a respected and viable component of the overall retail trade. The level of consumer confidence continues to rise showing that the stigmas that used to plague online retailers is a thing of the past.
Savvy internet shoppers use comparison shopping engines to find the best deals possible. Savvy merchants list their products where shoppers are shopping.
Comparison shopping engines are here to fill the intrinsic need of the online shopper. They gather together multiple merchants and millions of products for the purpose of comparison shopping. These engines provide product information, costs and consumer ratings in a usable format geared towards the consumer. A “click” from one of these shopping engines results in a reader landing on your site. Google Product Search, NexTag, Shopzilla, Shopping.com and PriceGrabber are the top five comparison shopping engines, based on market share.
Marketplace sites serve a different purpose. Sites like eBay and Amazon enable a seller to create a store and sell products from within their interface. Clicking on a product within one of these marketplaces does NOT send you to another website. Comparison of products, price and ratings of products and merchants are available.
