"On a related point, it is a wise practice to delete disabled keywords as a matter of routine, regardless of whether you intend to re-use them or not."
JonBoy asks why this is so. Here are some headlines:
* A disabled keyword is not showing your ad, but can work against you because the performance monitor sees it as still 'active' - and this can effect your overall statistics. If you delete it, this is not so.
* A disabled keyword is also still 'budgeted for' by the system that calculates your suggested daily budget. This can reduce the number of times that your remaining keywords will show your ad, if your daily budget is too low to show your ad every time. If you delete the disabled keyword, this will not be the case.
* If you don’t delete a disabled keyword, then delete the campaign it is in, you can't get to the keyword later to delete it. This will prevent you from being able to re-use the keyword at a later date. Gnashing of teeth will ensue.
* And finally, you don't have to look at that red asterisk any more. ;)
