We have been using voluum for about 4 months now, so far it has worked well with our website that receives most of its traffic via Google Ads (PPC). The reporting dashboard helps us see if we need to adjust some parameters or not! There isn't any specific dislike here. I think what they could improve more would be their support department. But overall everything seems fine. If you're looking for a PPC tool which will help you monitor and analyze your ad spend as well as show you how successful were your ads, this is definitely something worth considering! We started out by monitoring only our AdWords campaigns but then realized there was no way of knowing how many impressions our websites got. This helped us understand better whether our site's content and design were up to scratch or not. It also allowed us to know who exactly visited each page on our website.
