if I am doing a campaign focused on a single city and I'm trying to promote a bail bond service. Would I really only need one keyword, bail bond using broad match. I really don't care what else they type as long as it has they are searching for some type of bail bond. Right now I have stuff like houston bail bond, houston bail bonds, but wouldn't just bail bond as broad match cover those including "bail bond" and "bail bonds" or should I break out every phrase that I would expect them to type.
