The ability to create campaigns with different ad groups in one dashboard made it easy for me as an advertiser/marketer newbie who knew nothing about marketing or advertising! I can easily see what keywords are driving traffic from my website which helps make decisions regarding future content creation efforts; likewise seeing where people drop off before they convert helped us optimize our sales funnel (to be more specific).
Nothing much that was really bad - but if you're looking at this product because of its ease then there isn't anything else worth mentioning here other than just use them! They have done everything we've asked so far without any issues along those lines!! We were able to set up all three types of ads within minutes using their drag & click tools compared to having 3 separate accounts each costing over $100 per month.
