GBAbsolute game-changer for us Partnering with Quartile has been an absolute game-changer for us. These folks are wizards with Amazon ads, wielding their AI and machine learning like nobody's business. What's amazing is how effortless the collaboration feels. They plug into our systems, and voilà - our joint campaigns just take off, smarter and more efficient every day.

GBA year of great results I’ve been working with Quartile for almost a year now and I couldn’t be happier with the results. I’ve seen consistent improvement with my campaigns. The account team that I work with is prompt and very knowledgeable. Give it a shot, you won’t regret it.

GBTotal Disappointment I used Quartile before Covid and they were very effective. I have run my own Amazon PPC for a while and had ACOS running at around 40%. I went back to quartile in order to try and bring down my ACOS and increase sales. They were confident that they could bring my ACOS down into the 20% range but said that they expected it to take a month or two before their algorithm really kicked in. I used them for a total of 5 months and, during that time, my ACOS hovered around the 70-80% mark. We had weekly meetings at which I begged them to bring down the ACOS as I was simply losing money on every sale. They constantly promised to do so but month 5 had ACOS running at 75%. I gave notice and stopped using them. They ignored the notice I'd given them and continued to charge me after termination of contract. I am so disappointed with the results I got from them and cannot believe the way that they treated me after termination. This was a company who's AI algorithm might have worked in the past but obviously cannot cope with the way Amazon currently runs its advertising. Losing me thousands of $ was bad enough but then the way I was treated afterwards was appalling. I certainly would never recommend them again and would strongly suggest that potential customers look elsewhere.

GBHighest Recommendations We partnered with Quartile over 2 years ago on our Amazon US account and have since added multiple other channels because of the growth we have seen with the use of their AI technology. The team is so easy to work with always willing to pivot and make adjustments to help us meet our goals. Highest recommendations!
