embedding a survey into a pagebuilder page allows you to control the title/intro text and use only one "submit" button vs. having three buttons for "reset", "skip" and "Submit". Embedding the survey onto a pagebuilder page let's you create a small, concise email sign-up  process that can then be I-framed onto a non-convio web page of you website - and people can sign-up for a newsletter without leaving that web page.

However, more and more web pages are now secure pages, and chrome and firefox will not display a non-secure survey on a secure web page. Not a big deal, but there are bugs in convio when you embed a secure survey on a pagebuilder page. In IE, the thank you page will not display properly.
