Dynamic Keyword Insertion
I'm using DKI in one of my campaigns. Even when the keyword should fit in the ad space, the default text is being used. I can't get the ads to work properly. There's nothing inappropriate about the keyword insertion. Is there any other reason -- especially one that can be fixed without modifying the ads -- that could be causing this to happen?
Re: Dynamic Keyword Insertion
There are a number of reasons why DKI might not trigger. Two come to mind at the moment.
The actual search query may not precisely match your keyword. DKI triggers only when your keyword precisely matches the searcher's query.
The keyword quality score may not be high enough--keywords with quality scores of 5 or less may not trigger DKI at all.
