On the absolute flip side, if you have a brick and mortar that requires customers to come to you, you’ll want to build a distance from location extensions report. (Of course, this requires you to first have a location extension for your campaigns, which simply lists the address where a customer can find you.)
Once you load the report, you can see how far people are willing to travel to visit you. This is helpful if you’re a new business and start out targeting – say, 50 miles or so with your ads. You can see how far away people are converting from and if the money you’re spending to target them is worth it.
If you’re only getting a few customers at 40+ miles away, and your cost is too high for those, you can start to adjust bids or perhaps shrink your targeting radius.
