Hey guys,

Can anyone give me some clear information on the following questions please?

1. What are the key differences between Author and Publisher with regard to the "rel=" tag?

2. I realize one is intended for individuals and the other for companies but are there any instances where a business would use both? What are the implications?

3. I have a client that wants to hook up her personal G+ account to the business she heads up - is this advisable or should they use the company G+ account?

4. Can Author and/or Publisher tags be used on all pages within a website or should they be reserved for certain parts (for example, should author be reserved for blog posts and publisher be used for all other pages?)

Thanks for any help in advance,
