A few short years ago, Amazon.com decided to offer a CPC (cost per click) advertising model to help sellers create artificial relevance for an ASIN, and it has since exploded into one of the fastest growing ad platforms on the internet. The purpose is to provide an additional way to drive traffic and promote awareness about your detail pages. The program first began as an exclusive to 1P vendors only (Vendor Central) but has since become widely used by 3P vendors on the Seller Central platform as well. Within the Amazon advertisement family, you have control over all advertising and your Brand Store (formally Brand Page) for your brand(s) sold on Amazon.com.
