I like how it's easy for me as admin of my site because you can set up all kinds of rules which helps with different aspects such as traffic source/target or user behavior etc.. It also has great reporting features so we have everything at our fingertips! There really isn't anything bad about this product but if there was something i would suggest adding better customer support (i know they do offer phone calls). We use retargeting mainly from sales funnel optimization purposes where most people don’t even realize what kind of data analytics software their using unless someone points them out specifically.
