Hey all, The first question is that I want to know if I can estimate how many time some product was sold without having him in my site. I wonder if it posiblle to check it and figure if I should promote this product or not. I know that I can just crawl inside amazon products and than check it with Google, but need some better way for this. I will appreciate any kind of help! Thanks, Tal.
You should take a look at the salesrank attribute, returned by the API. The lower the number the better. It is relative to the category the product is in so keep that in mind (e.g. a sweeping brush with a salesrank of 10 is probably not selling more than a television with a salesrank of 300). Also take a look at the number of reviews - this is a good indication of the popularity of a product.
