It's very easy to use, have great customer service (quick responses) - I've never had an issue during my time with them! They are always ready for any questions or concerns you may need support about your account/campaigns etc., they helped me out whenever i needed it as well :) The only thing which was kind of hard at first but once u get used too its not much different from other systems like google adwords if thats what ur looking into doing ppl can easily do this using software instead og manually going through each keyword individually.
