I recently experimented with using google authorship and a google+ page for my site. It boosted the ranking a bit and thats nice. I have a lot of other sites and think it would be a bad idea to make google+ sites and authorship all under the same google account. What would you do? Create multiple google accounts to do this? I mean if i do this all under one account, google for sure knows all my sites belong to this account. btw i have all my sites added to the same webmastertools/GA account. dont they already know all my sites?
