All the graphics and images are really helpful

The option to add several different types of questions.

I really like the fact that everything is in the same software package. I can design and program my questionnaire in the software, link it to a customer database, host it on a secure server, send out invites and reminders to non-respondents and a summary report with charts is built automatically for me. That's just the basic functionality. Online surveys work across all devices by default - mobile, pc and tablet. In questionnaire design you add sliders and semantic scales, client logos and branding to make your surveys highly engaging. There are also essential survey best practice functions such as randomizing codes and seeding/piping/routing so that respondents are only asked the questions that are relevant to them.
