I'd really like to start looking beyond 'last click' keyword data for organic and paid search; the search terms that lead up to a conversion across multiple visits.
However, it seems that the vast majority of analytics solutions just report last click. I've read that Yahoo Full Analytics reported on this metric, but presumably this is now dead since Yahoo picked up IndexTools.
I currently use Yahoo Analytics Enterprise, so leveraging this would be ideal. If not, is there any other package I should be looking at before rolling my own solution?
