I recently met with a client (a UK-focused homewares company sold by the likes of Next etc) who were meeting with Amazon the next day . Amazon has told them that people search for their name every 6 mins on Amazon. This according to my calculation is c. 7200 searches a month. There are 8,100 searches monthly globally on Google for their brand name according to Google Keyword Planner - suggesting that Amazon is close to becoming the major search destination for shopping (if it isn't already!) in the UK.
