I knww Google +1 is getting popular now, just wonder can we put this icon into our Adsense Contents site? Not too sure whether will this violate the T&C of Adsense? Any idea? Please share your comments. Thanks
Yes, you can put Google +1 icon. There is no risk with using it. I am using it since last two months. If you remembered google also was showing message in Google adsense account to use Google +1 service.
Yes, they wish it to be everywhere, so do them a favor Also I recommend you use addthis.com widget so that your visitors can share your pages via any social media of their choosing.
