All your website are about the same theme? If so I'll create just one profile for them all in facebook and twitter.
The other problem you're facing is that be social is not so simple. You'll have to be not only unique and relevant (like you do with big G) but also interesting.
The best example of how to be social and sell is the "Will it blend" series. Obviously few people are capable of that, so better don't sell and focus on how to entertain user with things that may interest and engage them. Have you got commentaries enabled on your site (or an echo at least)?
In my experience videos, polls, controversial articles are the best choices iin this way but there are plenty of them.
