Many aspects of an account manager’s job can (and should) be automated in order to free up time to develop what the machine cannot do.
However, many tasks are inevitably carried out by hand; and, just because these actions are manual does not mean that they cannot be optimised.
Find out below the most useful shortcuts for SEA managers and users of the main Google online tools.
The examples are on Windows. Mac users should replace ALT/CTRL with CMD (with some exceptions).
