I intend for this to be a more detailed guide later on. But to give you the basics now,
You absolutely should control the following three things about your website (and internet marketing):
- domain name (account)
- Web hosting (account)
- Google my business listing (account)
When I say you should control these, I mean you should be the one who setup the account with the service (domain service, hosting service, Google my business).
You should have the password and username. It should be your info (business address, phone number) on all of the accounts.
What if it wasn’t done this way?
I plan to make a guide about that.
For now, contact me and I can give you advice.
