I have found myself a nice keyword for building an Amazon site. It has 3600 monthly searches and very low competition (9 in Keyword Revealer). I am however in doubt about this keyword, because it has no buyer or commercial intent. It is just a product keyword, without 'best', 'buy', 'review', ... For example: my keyword can be compared to 'tennis shoes' and not 'best tennis shoes'. My other pages could be things like 'Dunlop tennis shoes', 'Nike tennis shoes' and not 'best Dunlop...'. Summarizing my question: Is it worthwhile to build an Amazon affiliate site around a product keyword without buyer intent?
