I have been targeting the stat of TX in Adwords with sub targeting of individual cities. I do this so I can adjust bids for each city.
I did some other things that increased my CTR which in turn rose my cost by almost twice as much. I need to get my budget back down. From my DB I found that Dallas, Houston, & Austin is where almost all of my conversions come from. I changed my targeting to only show in those 3 cities and surrounding areas to be safe. This should reduce my spend by exactly what I want.
I understand how location targeting works for the most part the only thing I don't understand is how Google knows where somebody is on a cell phone when they are not logged into a Google service and are not using a Google phone.
How often does my IP change when I am driving around? Do cell phone towers in a certain area use the same IP's or does each one have its own IP range.
