Do you handle your clients Google+ account and if you do, how do you add pictures to their account? I've googled around and adding pictures to your own account is not a problem but as far as adding them to your client's account, can't find any information.
Would you need to have their Google email account information to be able to access it or how exactly do you go about it? Once the pictures are added, how fast do you see an increase in ranking?
Thanks in advance,
