"As the dust settles on Google’s launch of Google+ Pages for brands and businesses yesterday, we’ve dug a little deeper into the terms of service that each brand must adhere to on the network and found something very interesting.
One policy of Google+ Pages states that brands and businesses “may not run contests, sweepstakes, offers, coupons or other such promotions” directly on their pages. Instead, brands must link to contests on external websites or alternative social networks. Many brands, including ourselves, run competitions directly on networks like Facebook and Twitter so this may come as a surprise."
