I like that you can track all of your products in one place so its easy to see what is working or not within an account. It also helps with my SEO efforts as well because now when i have some new items coming out they are being tracked right away instead of having to wait until after launch date which would mean no tracking data from prior days/weeks etc. Sometimes there will be lag time if things go down but other than that everything seems great! Just make sure you do enough testing before rolling this into production mode otherwise you wont know how many times something could break during such high traffic periods. Having more information about where customers come from makes managing campaigns easier since we're able to target specific areas rather then just guessing at regions like most tools tend to provide. We were looking around trying to find ways to better optimize our website performance by gathering analytics info without relying solely upon Google's API. Our team has been using amazon insight tool along side google insights.
