I've been using this product for over 4 years now, it's very easy to use with lots of features that can be used in your campaigns as well! The support team are also great people who always respond quickly when you need them most (or at least they try their best!).
It would have helped if there was an option where we could see how many clicks each ad received so far - but apart from some minor issues like having too much ads displayed per page etc., everything has worked fine up until recently which hasn't made me happy :( Hopefully things will improve soon though :) Try out all options available before deciding what works better or worse than others; different formats work differently depending upon whether someone wants more impressions/clicks vs conversions / sales generated by those click-throughs! We're able get our clients' website visitors redirected towards specific landing pages after clicking.
