Online merchants are competing for customer attention and loyalty in an Internet landscape where people create their autobiographies across social networks and businesses have to discover a reason to be relevant in that narrative.
Blogging, which some suggest is a waning art for individuals, can be a publishing platform for savvy online stores that create content to better engage potential shoppers and build a relationship with them.
Ecommerce-related blogs can focus on product information, how-to demonstrations, or even social topics. Examples of good ecommerce blogs include REI and Toms.
