Used properly, the tag team of a Google+ Profile and Page can be a powerful asset. Combined with a correct Website setup, it's a great way to build up your Business and Brand.
First Step - Setup
Before you do anything on Google+, you need to ensure that everything is set up properly. Build a strong foundation by connecting your Website, Google+ Page and Profile (or Profiles, if you have a Team).
Do this properly by following the instructions straight from Google:
If you follow everything correctly you will have built a strong network of links between your Website, Google+ Page and Profile. This is your foundation and an essential starting point for Google+.
Second Step - Roles
Next, you need to decide on Roles. I suggest keeping things simple by assigning Broadcasting to the Page and Networking to the Profile(s).
What does this mean in practice? It means letting your Personal Profiles do the work of Commenting, Following and +1'ng.
Let the Page stay on the Page. I recommend restricting Page actions to Posting and replying to comments on it's own Posts. (and to be honest I'm starting to lean towards thinking that maybe Profiles should be doing even that task.)
But don't take my word for it. Experiment! See what works for you and then stick to it.
Third Step - Awareness
The third step is making your followers (and potential followers) aware of these roles. If you choose to have a Personal Profile represent your Page around Google+ then you need to tell people.
- Make announcements on your personal Profile and on your Page letting everyone know.
"John is our Community Manager, so Circle him as well to stay connected!"
or "I'm the Community Manager for this Page"
- Put up pictures. (the Photo strip at the top of Pages is great for this)
- Put a logo on your Team's Profile pictures (Consistency)
- Announce Hangouts "with the team".
Fourth Step - Engage
No secret to this one. Get out there and do your stuff. Use the networking potential of Profiles to find out what people want and give it to them.
Google has provided an awesome engine for you. Use it.
