We've been running a couple of little giveaways over the last few months linking our twitter account and whatever product page we're promoting at the time.
The +1 button is on the product pages now, so this time around we stuck a thing on the bottom of the contest box saying, 'while you're here, +1 us!' and it's been better than expected.
This particular page got 132 pageviews yesterday, and 14 +1's, just because we asked people to click it.
