I never used Export option till today - huge overlook on my account. Now I can see how benefitial that could be to have daily cron job and export results on to my pc. Well, since I wasn't doing it already I don't have any data on my previous rankings, but there is some data appearing on the graphs for each keyword - would it be possible to have "export all" option for all that data which is available and not only for the last checked date?
Allright, I'll start saving it daily then. Would it be something useful to add? Or its a big overload on your servers? The data could be limited to so many months or days... I'm just wandering.
