I have been helping a retailer recently try and get control of their business profile on Google. It was setup for them by another party that has been reluctant to give the local retailer access.
Google has been no help in resolving the situation.
Setting up a Google profile is easy. My advice is do it yourself, control how you want your business represented to the world. The profile is about you, after all, and not how a bland marketer thinks your business looks.
A Google profile is a living thing. If someone else sets it up for you, are they going to maintain it? Probably not, do it yourself, be responsible for our your business is seen by the world outside.
While I appreciate to a non-tech savvy person it may seem an easy decision to let someone else do this for you, it is not because they are not you, they are not your business. It would be like you letting someone else control a key part of your business, a key resource on which you rely.
Doing it yourself is easy. No tech skills are required. Google offers advice. This link from Google takes you to where you can get started: https://www.google.com/intl/en_au/business/
Hootsuite also offers advice on setting up your business profile that I think is worth reading: https://blog.hootsuite.com/google-my-business/
Please, don’t be duped by people who say they are the experts to do it for you. This is absolutely best done by you.
