How powerful is Amazon’s private label?

In the online battery business, as noted above, 94% of batteries sold online are sold through Amazon, already a staggering metric, but Amazon’s own brand accounts for almost 1/3 of all battery sales online and has grown 93% over the 8/15 – 8/16 year. While price is certainly a factor, especially in the battery category, where brand loyalty is extremely low, Amazon has created a speaker product, the Echo, that has significant appeal to consumers, and while it doesn’t have the highest conversion rate[i], it does have the highest proportion of product views.
All in, Amazon has taken it incredible retail might and begun to use that strength to hawk its own products, and while competing with its customer base, is likely going to expand the number of categories in which it sells its own brands, despite the conflict. While it is hard to imagine that this will not cause some consternation with its B2B customer base, Amazon’s reach is so great that in the long run, BTB customers will have to accept that Amazon itself could dominate their product category, potentially thinning the competition to those able to produce more competitively priced (batteries) or more innovative product (speakers).
