keywords by state? Other?

does adding states or cities help?

[donny2times]

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

Google and Overture sometimes have problems when your ppc keywords are too similar and it would be not the easiest campaign to manage. Unless there is big money at stake, I would go with one general keyword.
