Welcome to the Q&A Forum

Google allows you to choose up to 20 locations as service areas, and you can choose based on cities, counties, or zip codes. I'm trying to determine if zip codes, cities, or counties are better to select for our GMB profiles. We are located in the US. I am thinking it's best to use all 20 areas allowed on a profile as long as they are relevant, generally giving Google all the info they will let you provide is best. I also am leaning toward using zip codes because it also includes the city when you choose by zip code. For example: Entered the zip code 21009 and the service area selection provided was: Abingdon, MD 21009, USA Entering the city/state returns a selection of Abingdon, MD, USA I also think it may have to do with how people search and find your business as well? Does anyone have experience with this? Best practices? My google searching has not turned up any reliable info.
