Another social network is here, Google+, making it even harder to keep all your profiles--Facebook, Google+, and Twitter--updated. Sometimes we get so engrossed by one (Google+), we end up neglecting another (Facebook).
To make things easier, there's a simple way to post directly from Google+ to Facebook without any extra extensions, or third-party apps.

Method:
Go to Facebook.com/mobile and copy the e-mail address provided under "Upload via Email".
Head to Google+ and create a new circle called Facebook (or Post to Facebook). Then, add a new person and paste the e-mail address you copied in the first step.
Whenever you want to mirror a Google+ post on Facebook, share it with your Facebook circle, and check "Also email 1 person now yet using Google+".
