I am looking at buying a zipcode DB to use for my PPC campaigns. I was wondering if using all the states/cities that my client is doing business will help with my PPC campaigns? Is this a better solution than using a "broad" keyword along with "negative" keywords (states not doing business in)?
I have created a keyword list using Google, Overture and Word Tracker tool sets but I only have 200 or so keywords.
Any input would be much appreciated
