But technically having more that one FB or G+1 account is against their TOS.
That is no longer true, you can have a page for every site you own and that is best practices.
Not sure what the exact rules on Google+ are but I am pretty sure that you are only allowed to use your real name so I doubt you will be able to have a separate one for each niche.
You can now create pages for websites.
