is there any way of finding out the basic demographic of who would be searching for a given keyword? or is it simply guesswork?
By demographic, i assume you mean age group, and/or salary, race, etc. I'm not sure there would be any relaible data on that. You can't tell how old i am by my ip address. But major shopping sites would have data on their customers. But thats private info.
more just age really i guess. but yeah i didn't expect there to be a resource, was just wondering really. would be great info to have though
