Im fortunate to have a business where despite there being competition the Max CPC is 1.00 however ive geo targeted my ads to only the zipcodes and cities I service with my business. My logic is - Id rather go a day without a click but when i get that click and someone calls me or emails me and that reverts to a sale it was worth it. Versus having to pay for clicks from Texas when they could never covert to a sale because its out of my service area which is California. I think a lot of adwords users fail to geo target and this results in unwanted clicks and quick wasting away of there budget. Also by geotargeting I can have a small budget say 100 a month that suits me perfectly. With my campaigns im pretty much guaranteed to be in the top position in adwords for the specific keywords ive chosen and I also studied my competition so i know pretty much what keywords they use and I now use them as well. I don't think i could do more.
