The Visits and back link data is a really nifty feature, but the data fetching take very long time if you got a larger list of keywords. It would be great if the update tasks also could be scheduled

Actually, since the update with bounce-rate data the request create a CAPCHA situation all the time. Even with anticapcha it is impossible to updated the data for larger (+50 keyword) sets.

Please make it possible to enter a Google API-key, as it is now - the feature is unusable

Please keep in mind you have the ability to enter your Google Analytics login in Preferences -> Google Account settings in order to get the visits number for your keywords.

Of course, without the login it would not be possible to fetch the Analytics data at all

As it is now, after ~50 keywords, Google start to block the traffic and displays CAPTCHAs – really strange since the calls is authed:

(On this screenshot I got 10 concurrent calls, but I get the same result with the default 5)

Since it's not possible to schedule the updates it's even a bigger hassle - Ranktracker is blocked for further use and costly ANTI-CAPTCHAS is used. The pausing when Google is blocking the calls make the updates really long: up to a whole work day just to get traffic data for a set of keywords
