GeoIP is pretty accurate at the state/country level for most users, but you will run into precision issues at the city level.

A bigger problem seems to be that many forget to continuously sync their IP DB with their provider. Your targeting is only as good as your IP -> Geo map.

My team built a tool for testing GeoIP implementations here: https://www.geoscreenshot.com to get around the issue of testing if it works.
