"I decided to give Quartile a try after multiple failed attempts with other Ad agencies. We have been with them for over a year and a half and we have been extremely impressed with their use of their AI technology as well as their customer service. The team is so easy to work with always willing to pivot and make adjustments to help us meet our goals. We started with amazon to test it out but added google a few months later due to our growth. Highest recommendations!"

"I decided to try Quartile for managing my Amazon PPC campaigns, but my experience has been incredibly disappointing. Despite all the promises of AI-driven optimization and data-backed decisions, the results were underwhelming at best. I was managing my own PPC and had the account stabilized at 34% ACOS, Quartile using their AI approach not only took the ACOS to well over 45% but also dipped the sales so much that in my 9 years of selling on Amazon for the first time I was selling at a loss. The platform seems to lack the flexibility needed to address the unique aspects of my campaigns. It felt like a "set it and forget it" tool, but unfortunately, it forgot to generate any meaningful results. My ad spend increased significantly, but my sales slowed down. There was no improvement in ACoS, and it was frustrating to watch irrelevant keywords being targeted, resulting in wasted budget week over week. In the end, Quartile didn’t deliver the level of optimization or insights I had hoped for, and I ended up having to manage much of the process manually. I wouldn’t recommend this platform if you’re looking for a true, data-driven PPC solution that you can trust to actually improve your campaigns. In my opinion, for a small to medium seller Quartile is a bust even if they offered it for free."

"I've been working with Quartile for 9 months for my Amazon Advertising. So far, we've had great communications and have seen better results than our PPC manager before. The tech has been a gamechanger for my growth and to focus on other aspects of my business."
