I am newly (month and a half) into the google adwords campaign stuff. Tell me if I am being silly. Whenever my keywords are "on hold" or "in trial" I usually delete them so all my keywords will be displayed as "normal". At one time in an ad group out of 42 keywords 29 were on hold. I had to delete them. Is there a formula or percentage or ratio as to the amount of words that can be "on hold" or "on trial" in a google adwords campaign. Tell me cause I want ot know!
