On Friday, Danny Sullivan reported at Search Engine Land that Google is planning to give webmasters a year worth of top search query data within webmaster tools.
Currently, Google only provides 90 days worth of this data. They do so because they stripped away the referrer data years ago, with some reporting 70%+ in [not provided] results due to this change.
So Google is finally giving in and giving webmasters at least a year worth of keyword data. Thing is, it is not perfect, it is only the top search queries, but it is better than nothing.
There is no ETA for when this will launch, but it currently is not.
