Unable to add keywords?
So you've added free keywords to one of your advertisers but they can't add more keywords in their account? This is related to the total number of keywords in that advertiser's package. For example, if the total number of keywords in a package is 10 keywords and the number of free keywords is 20, then the system will only let you add 10 keywords. Simply put, the number of free keywords cannot be higher than the number of total keywords in a package.
Have a great week!
