Credibility and Persuasive Web Design

Convince people to stay on your site, believe it, and take desirable actions

Users judge websites in a fraction of a second and their decision-making is largely controlled by unconscious thought, not logic. Much of what influences users to take desirable actions is not as clear-cut as we would like to think.

Focusing on branding, design, and usability is only the starting point. Understanding the psychology behind motivation and action and how to incorporate that into web experiences and your design process can take your site to the next level.

"This was a very helpful course. As a designer for an ecommerce site, this will definitely help me make changes to increase conversion."

Attendee Feedback

"This is just what we were looking for. Test driven and statistical background on whatever we are going to design. Great choice."
"Great practical guide on how to use behavioral theory to optimize."
"The info Jen presented was extremely pertinent to challenges I'm currently facing as a UX designer, so this class was very valuable to me. The real world examples were clearly related to the subjects and I feel like I'm much better educated about persuasion and credibility in web design. The wireframing exercise was great, like a workout for my brain."
