When I came back to quartile, I had been running my own Amazon PPC at an average of 40% ACOS. I was wanting to bring this down and, obviously, Quartile claimed that the could do this and it would only take a month or so for their algorithm to achieve this. Each month they came up with excuses as to why my ACOS was hovering around 70-80% This went on for 5 months. I lost a small fortune during this time! In January I emailed them to give notice and stated that, if they couldn't get my ACOS below 50% during the next month they should take this as my notice. The ACOS remained high and so I terminated my contract with them. They then billed me for a further month, ignoring the fact that I had already given notice. Their supposed AI algorithm simply doesn't work with the new complexity of Amazon advertising. I would not consider using them again and would highly recommend that you give them a wide berth. They promise the world and completely fail to deliver.

Quartile has always been very helpful. The reps are willing to woke with us on anything we need or don't understand and so on.
