I do apologize for being the contrarian voice in this debate... and let me premise my comments with the fact that I love this forum, I love the information shared and the ability to interact with like minded people who share an interest in local search... I'm very thankful and consider it an honor that I even found this forum in the first place and that I'm able to take part here (so thank you for that)...
But (and now the contrarian part... but respectfully) I'm confident that adding service area zip codes, surrounding cities, counties, etc... CAN in fact increase your presence, rankings, and productivity from those surrounding markets.
I have two clients that prove this theory is real.
I would sit here and write out the whole story, but unfortunately I have podcasts that I need to get recorded, and my house is finally quiet at the moment.
Perhaps I'll come back here and do a more in-depth write up... but I can tell you definitively that adding surrounding geographic areas as your targeted service areas does generate production (phone calls, website visits, views in search, views in maps) for your business.
For now you can reference this post here:
Service Areas Clarification Needed - Local Search Forum
In that post I went a little bit deeper into this topic and shared screenshots of the zip code targeting strategy we implemented.
And you can see from our reporting that we basically doubled this client's "Actions" productivity across the board.
I can tell you though... the reason people believe this is not possible is because the client base being referenced (i.e. GMB's where this doesn't work) is probably due to a lack of location authority.
If you do not have enough location authority, it doesn't matter what you do to optimize your GMB, website, etc...
In other words, with zero location authority, you pretty much have to be standing in your office to see your GMB show up in the 3 pack.
However, with substantial location authority, you can generate productivity from local search / maps from surrounding zip codes and geographic areas.
In my view (again, I apologize for the contrarian position here) it is 100% possible... if and only if you have enough location authority to power your rankings at wider radiuses from your location.
