Where can I get the link for the created survey?

If you want to distribute your survey with help of a link, you need first to open it in Edit mode and click the button "Activate" in the top on the left. Then in the pop-up window choose "Public web survey". You will be presented with web and mobile links to your survey, QR-code and Java-script code, which can be embedded into your website page with help of an iFrame.
