I was asked to set up a company Facebook page some time ago according the following format, with an underscore connecting the 2 parts of the business name: 'Companyname_aus' The company HQ is in Germany, their business name is 'COMPANYNAME AG', their Facebook name is also 'COMPANYNAME AG', with a space, no underscore.
I just googled 'COMPANYNAME Australia facebook' and noticed that that the majority of results are of the HQ Facebook page, 'COMPANYNAME AG', including the first result.
Considering that the Companyname_aus has been live more than a year and posts more frequently that the HQ one, I feel it should be dominating the SERP.
Question is, if the page was name 'Companyname Australia', would it perform better?
Is using the underscore in a way that changes the business name a mistake (companyname_aus)?
Note: the 'COMPANY AG' page has a lot more followers, and would have also have some followers in Australia
