I was thinking about the possibility to analyse ISP proxy servers log
files(configured to show extra data) to gather information about
internet usage and to carry out keyword research. I live in a small
country and the only statistics we have is from an agancy that collects
information over the telephone.

What do you think about the idea?
Is it possible(due to the amount of data)?
Are there any solutions that exist/could be helpful?

Thanks for your answers.
