The business of conducting transactions and sales online is referred to as ecommerce. Generating traffic, visitors and consumers to an ecommerce site is referred to as ecommerce marketing. Ecommerce marketing may take many different approaches to generate traffic and interest in a site, business, product or services, but the most common (and arguably most effective) is search engine optimization.
A landing site for ecommerce activity should appear organically for a consumer. If a link or advertisement is obtrusive to internet activity, a consumer may be less interested in visiting or following the link. Professional search engine marketing often times can assist a site or business with high visibility for their link as well as an organic approach to present a consumer with an option to continue their search via a search engine.
