A keywords blacklist is essentially a list of keywords you don’t want to use for advertising from the account. However, the ban on generating ads with particular keywords concerns only their precise wording – the ban doesn’t apply to matching words. That’s why you have to enter the precise form of the keyword you don’t want to use for advertising.
ATTENTION! The keyword must be perfectly identical to the one you wish to exclude, including the type size and punctuation.
For example, if you enter “Reviews” into the blacklist, ads for “reviews” will still be displayed.
