The ability to create multiple landing pages with different content depending upon visitors actions is great! It also allows you to see what your audience clicked through so that if there was something they didn't like or wanted more information about then it can be easily fixed before going live. I would say their support team could use some training but once you have set up everything correctly this shouldn’t become an issue at all. Creating several versions of our website using various landing page features has helped us get better results in terms of conversion rates which helps improve revenue as well as marketing ROI.
