You can setup rules to encourage social posting after a survey - we see good conversion rates for promoters who then use Twitter, Facebook or TrustPilot to post a good review and so continue to promote you business.
Select the Project/Settings/Promote Social Posting menu option and toggle 'on' the social platforms you would like to display.
Tip 1: it sounds obvious, but we have found Promoters are the best source of social posts, so make sure you display this options to Promoters by selecting this group from the drop-down menu at the top of the settings page.
Tip 2: if you would like to generate a pre-formed tweet for your users when they click on the Twitter icon, use the Twitter scripting code within the field.
