I recently ran a couple of webinars for a client on very short notice. I ran out of time to write a white paper (since I was developing the content and the promotional copy at the same time), so I worked with the hosting company to include a few brief survey questions in the registration form and during the event.
The result? Enough data (10 questions, 150+ respondents) to publish a "survey" (not statistically significant) of what executives in the industry were thinking. Created in Power Point, saved to a .PDF, the charts and graphs provided enough eye candy (and benchmarking data) to make the call-to-action even more compelling than the white paper we originally envisioned.
