The Facebook Send Button
How It Works
The Send button is a social plugin that websites can use to let people send a link to a friend through Facebook Messages, post it to a Group, or email it to an individual. For example, if you see a Mother’s Day gift idea on 1-800-Flowers.com, you can now send a message or email to your family members to discuss. Or say you’re training for a marathon and you come across a great article about running shoes on The Huffington Post. Now you can share it with your entire running group in just one click.
The Send button drives traffic by letting users send a link and a short message to the people that would be most interested. They don’t need to leave the web page theyâ€™re on or fill out a long, annoying form. Compared to the alternatives, the Send button has fewer required steps, and it removes the need to look up email addresses by auto-suggesting friends and Groups.
How to Add the Send Button
The Send button can be easily added to existing Like buttons or as a standalone feature. Developers currently using the XFBML Like button can include the send=”true” attribute in their Like button code to generate a combined button, and those using an iFrame version of the Like button will need to upgrade to XFBML to display a Send button. The following code will generate a combined Like and Send button:
<fb:like href="example.com" show_faces="true" width="450" send="true">
Developers can add a standalone Send button with the following code:
