CCAs & Engagement – An Uncommon Way to Engage & Convert Prospects in Your SaaS Free Trial. A few years ago I came up with a set of metrics that I called Common Conversion Activities – or CCA – that I defined as “The things that all or most paying customers do during their trial.” In July 2012 I gave a 54-minute presentation where I introduced the next version of this ever-evolving set of metrics for measuring Free Trial success, the CCA, and I want to share that with you now.
