The widget for an off-site review is a little tricky. You will need to create your off-site review, using our off-site review template and then insert the url link for your blog review and insert it into the review template. Once you submit the completed on-site portion of your review, the widget is generated for you. You then have to go back to your blog portion of the review and insert the widget.
So, you don't actually see the widget until your review is submitted to Eden. Hopefully that made some sense.
Just let us know if you have any additional questions.
