Pause or Enable Campaigns, Keywords or Ads on a Specific Date

UPDATE 2013-12-13: Added the ability to work on Ads as well.

I've seen some questions posted around the forums asking about enabling or pausing keywords on a given day. It is pretty simple to do using labels and scripts. The following script will run through your account and look for keywords labeled with "Pause on " or "Enable on " and perform that action. If you would like to just use dates, you can set the two prefix values to be empty strings (""). The format of the date is YYYY-MM-DD (2013-05-01).

Thanks,
Russ
