Great for Optimization

For testing scenarios, including conversion rate optimization, Kibo Personalization (we've used it as Monetate) does very well. The interface is fairly intuitive, and it is a very powerful tool, allowing us to make CSS changes easily without needing to do a whole code deployment with our development team. Product Recommendations was a long and painful project. We were promised it would work well with Magento and could display parent/configurable products instead of children/specific variant products. In my experience, they could never get it to work properly, and after many months of struggles with their team, they came back and told us it wasn't recommended that we use it for parent/configs—complete fail.
