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.

Insights and Strategy I have had a great experience working with Quartile for my Amazon Advertising needs. My Account Manager is knowledgeable, actively monitors the account and is always on top of things. On our biweekly calls, I receive valuable insights and strategy recommendations that have helped us to grow our core business and launch new products with excellence.

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.

Stayyyy Awayyyy Stayyyy Awayyyy, unfortunately they like many other Roomie companies will tell you it takes at least 2 months for results. So their trick is since they have a 3 month contract they figure by the time your done paying them the monthly fee you can cancel service and they just pocketed your fee and wasted your hard earned money on budget. BEAWARE they Outsource Out of the Country to Brazil and cheap countries so they can pay cheap labour and use people that barely speak English. SCAM SCAM SCAMMMM
