Critics say the logic behind the labels isn't always transparent to consumers or brands and fear Amazon could use them to prop up its growing range of private labels.
In a blog post on Friday, Marketplace Pulse Chief Executive Officer Juozas Kaziukenas said that the top brand label could act much like the account verification badges used by Instagram or Twitter, which are designed to connote legitimacy. The label, if implemented, could have "substantial impact on how shoppers decide which products to buy," or how brands compete against cheaper private-label products, Kaziukenas said.
Amazon accounts for about 40 per cent of online sales in the US, according to researcher EMarketer Inc. and fueled the growth of e-commerce.
But the free-for-all of its digital shelves dented the cachet some consumers assign to big brand names. Research by Marketplace Pulse earlier this year showed that roughly 1 in 5 product searches on Amazon included a brand name; more often, customers were content to thumb through Amazon's catalog.
Consumer goods makers have long complained that Amazon's Marketplace, which lets independent sellers list their products on Amazon, opened the door to widespread counterfeiting. Amazon has responded with programs designed to give brand owners more control over how their products appear on the site, including the ability to delete some suspect listings or report them to the company.
