(a)is there a way to temporarily 'switch off/on' or 'suspend' my campaign say if i'm going on holiday etc - i understand there is delete/undelete - is that the same thing?
(b)for tracking - i understand you can use 'keyword ** cpc ** url' in the ad group keyword list.
using the above format is it possible to append the url with say the 'ad group name' etc or in particular the 'cost of a sale' (that will obviously vary)? - if so can you please supply example string to show required variables?
(c)can anyone report on customer feedback if any, regarding the possible intrusive affect of the required tracking code placed in say the 'thank you' page.
i am worried that some may not return due to this.
much appreciated.
