The social media share buttons lets you share a page with your friends and contacts using your social media channels.
The ‘Tweet’ button allows you to share a web page across Twitter as a ‘Tweet’. Each tweet can be up to 140 characters in length.
The Facebook Like button lets you share content with your friends on Facebook. When you click the ‘Like’ button, a story will appear in your friends' News Feed with a link back to the website.
The Facebook Send Button allows you to send a web address as a message to your Facebook friends, to your Facebook group, or as an email to any email address. While the ‘Like’ button allows you to share content with all of your friends, the Send Button allows you to send a private message to just a few friends.
The Google +1 button allows you to give a stamp of approval to a page you like and add it as a useful site in your Google profile’s +1’s tab. By clicking the +1 box, a story will also appear in your Google+ profile page for your friends and contacts to see.
Don’t use Twitter, Facebook or Google+? ‘Add This’ lists over 300 other social media channels. Simply click the Add this button to find your channel and share.
