You can embed a survey URL in a web page. This is easy to do if you have a CMS that supports modal popups. Most CMS platforms like WordPress, Drupal, and Joomla will allow you easily create a modal popup using a plugin. Check your extension library or ask your webmaster for more details on how to do this on your web site.
