Great support team! I work with them daily to make sure our site is producing results for us as well as we expect it too (and more!). The tool itself has been very easy to use so far - not much learning curve at all if that's what they mean by "smooth". They have some great tutorials out there online which can be helpful when looking into things like tracking conversions etc. You are paying monthly fees but this seems fair considering how many other tools charge per click or something similar where smoothconverion helps in setting up campaigns/triggers instead of being charged after each visitor hits an ad / link through their platform. It really does take care off most issues related to conversion rate optimization without having to go down routes such as PPC ads or pay-per clicks.
