I’m surprised that nobody on “openclue”:http://www.openclue.org/ut has talked about “google trends”:http://www.google.com/trends yet.
For my part, I think it’s a great concept. If I was doing any kind of marketing research, having that searchable interface to google’s stats would be a very powerful tool. To me it seems natural that there will be a ‘paid’ form of access to this data with extra features later just for advertising. Maybe it’d be just a part of your advertising cost?
The features that I see lacking currently, are some form of data export (csv, etc) or service to query this data. And second, the one I would like the most is the ability to localize more parameters, specifically limiting what search types were performed, eg images, blogs, groups. Narrowing those fields could give even more powerful data.
