Absolute 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.

A 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.

Quartile Turned My Business Around In our category on Amazon competition is fierce and we needed to find a way to get an edge. Standard PPC management wasn’t cutting it even when we brought it in house and our ROAS was degrading. Once we onboarded with quartile we started to finally see the light at the end of the tunnel. ROAS gradually increasing every week, and their team of experts manage the service for us freeing up overhead costs we were paying for other solutions that just didnt work. Happy to say we're finally back on track and scaling with quartile.

Total 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.

My company has been using Quartile for… My company has been using Quartile for a long time. But lately, its bidding feature isn't working properly. Spending money on it now might be a waste because it's not delivering results. They made the cancellation process harder as well. I strongly recommend not using Quartile. It will cost you a lot of money.
