Amazon A9 fuels the website product search box which displays product results for searching customers. This algorithm decides which products to display and how high those products will rank based on a host of criteria Relevance to search words Previous customer behavior and preferences Quantity of past purchases of a specific product This Amazon bot s can boost your products rank by bringing unlimited traffic to your product page. The traffic looks so natural because this smart bot is able to simulate real human behavior like scrolling clicking some page elements and even adding your products into the shopping cart. On the other hand although closely related to my previous point we have another study the Bloomreach study on the state of Amazon. Among other interesting things it tells us that when a buyer is looking for a product he starts off by searching it through Amazon before any other search engine. It is important to note that 28% of total searches are done using Google Bing and Altavista search engines. We are talking about transactional searches that is searches that are 1% sales oriented not searches to get information or to consider whether they need that product or not.
