Google Plus
More viral social power to your deals - we have integrated Google Plus!
Yeah, another robust way to spread the word about your daily-deal site. Visitors can +1 your deals using their Google accounts exactly the same way like they re-Tweet or Send them to Facebook. No settings from your part just toggle it on the Google block of Settings page of Admin section and that's it. A new button will appear in "Share this deal" box on top of each deal active or recent.
If you haven't already set up a Google Plus page, you should really go for it. This social network has a specific audience a little different from Facebook or Twitter. You can easily segregate your audience by locations and categories (creating a separate circle for each one) and have better targeting in your promotional communication. So don't hesitate to link Google+to your daily deal site and grow your audience a little more.
Trick: spy on who "+1"ed a deal and add them to your circles.
