I sell books on amazon. I would like to increase the sales of the books, so require someone to see if the books have been set up optimally. For example I am not sure what the best setting for example “Adjustment bid by placement” settings (e.g. top of search, rest of search and product page) and whether the books have been effectively optimised (e.g SEO) on Amazon etc? Anthing that i as a general user have not considered.
