You can have more than that, but only '100 active' at one time. I have a few accounts with 120/130 campaigns. At that sort of size, its best to start up a new account...
is it possible to delete the campaign ? i've tried delete a campaign, adwords mark it as deleted but i'm not feel comfort if it's not totally dissapear, any suggestion ? Thanks
I've got 90 right now. You can have as many as you want directed to the same url, but they won't show your ad more then once per keyword.
Deleted or paused. If you have 100 active campaigns and want to switch on another, you will have to pause or delete another first.
