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.

Quality Service with excellent Service Manager We have been working with Quartile for 11 months. Flavia, our Service Manager takes time each week to discuss with our Team any questions or concerns along with charts, graphs on how our product is performing.

Scaling up profitably! Quartile helped me completely turn around my business. I was able to take a 1 ROAS account spending 40k/mo to 1.25 in just a few months and we're still consistently getting better and better return on ad spend every week. Can't wait to see what heights I can scale to with this team of professionals and and their programmatic ads management solution.

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 is a game changer! Quartile is a game changer! As an enterprise partner, we deploy their tech across many client accounts in numerous countries. Without a robust technology, we could not run so many campaigns effectively. Being a brand builder first, and having been in the industry for over 20 years, we’ve seen it all. We’ve used competitors to Quartile and frankly, their AI bid optimization is the real deal – not just hype like most others. We've seen tangible results and improved efficiency in our campaigns, many exponential. Negative reviews and skepticism usually comes from those expecting to set and forget. AI still requires human intelligence to fully capitalise, and when you combine the two you see real results. Their team is amazing, and the technology is top-notch. If you want genuine results, go with Quartile!
