Sharing your quiz to your Facebook business page is as easy as copying/pasting a link. However, first, you need to decide if you want the Facebook share to link to your quiz on the Opinion Stage site or to your own site. Following are instructions for doing both.
To share with a link that sends to your quiz on OpinionStage.com
From the Opinion Stage item dashboard, go to the item you'd like to share and click the Share tab.
Open the Share Link tab and copy it or select the Facebook icon to share the quiz directly to your feed.
Paste the link in your Facebook Business page if you copied the link.
Note: You can remove the link as soon as the quiz loads on Facebook and add your own caption.
To share with a link that sends to the quiz embed on your site
From the Opinion Stage item dashboard, go to the item you'd like to share and enable the Social sharing bar:
Publish the item & click the Share tab.
Choose the correct CMS tab and copy the quiz embed code for your website (read more here).
Paste the copied code into a page on your site.
Run the Quiz until you reach the result screen.
Click on the Facebook button and follow the Facebook sharing dialog instructions to share it on your business page.
