First of all – love what you have going here. I blundered onto the site last summer, and have had a great time making & posting music for sale. My sales aren’t through the roof yet, but I’ve gotten enough to encourage me to keep working.
I’ve been doing a lot of keyword research on Google lately while trying to get a webpage to rank higher, and the thought occurred to me that it would be really handy to have the same thing here. If artists could see the sort of keywords buyers were doing searches on, it could bump us on to the right track to meet their needs and increase sales. Everybody wins.
I would think that Google analytics could make this a pretty easy addition to the next update, and increase sales all-around for everybody. Just something to think about.
