"Transparent, Data-Driven Results—Quartile Made Our Ads Transition Seamless"

5/5

What do you like best about Quartile?

What I like best about Quartile is how quickly they delivered real results while keeping the process transparent and easy to understand. Coming from a business that grew 100% organically, we were cautious about ads but their team made the transition seamless. Their strategy, execution, and data-driven approach gave us confidence right away. Review collected by and hosted on G2.com.

What do you dislike about Quartile?

The onboarding phase could benefit from increased speed and efficiency. However, post-onboarding performance, communication, and results have been strong and consistent. Review collected by and hosted on G2.com.

What problems is Quartile solving and how is that benefiting you?

Quartile is helping us maintain our ranking and market position while expanding our reach. One of our biggest concerns was not losing the organic traction we built over the years, and they’ve done a great job protecting that. At the same time, they are helping us re-engage past customers while attracting new ones, allowing us to grow without compromising our existing foundation. Review collected by and hosted on G2.com.

"Effective Tool for Managing and Scaling Advertising"

5/5

What do you like best about Quartile?

The ease of launch and setup is excellent. Getting up and running is very straightforward, making it almost a no brainer to go live quickly without heavy upfront effort. Review collected by and hosted on G2.com.

What do you dislike about Quartile?

The platform is very advanced, which can come with a learning curve. In some cases, it feels more dependent on account support compared to other tools where I can more easily make adjustments on my own immediately after launch. Review collected by and hosted on G2.com.

What problems is Quartile solving and how is that benefiting you?

Quartile helps us efficiently manage and optimize existing campaigns, launch new campaigns quickly, and scale advertising efforts at levels that would be very difficult to achieve manually. The platform automates complex decision making and optimization that would otherwise require significant time and hands on effort. Even as overall Amazon advertising costs have increased, Quartile has helped drive incremental sales while improving efficiency and lowering ACOS, which has had a meaningful positive impact on performance and profitability.

"Great Company!"

5/5

What do you like best about Quartile?

Everyone we have worked with at Quartile has been great! Our account manager Diego is fantastic to work with. They always keep me informed about what is going on with Bi-weekly meetings, and when I want to make a change, even a major one like we just made today they are willing to go above and beyond to make sure that we are getting exactly what we want. Fantastic team, I highly recommend them to anyone who is considering trying their product! Review collected by and hosted on G2.com.

What do you dislike about Quartile?

Quartile provides a pretty cool dashboard with lots of good information about your ads, but I do wish it was a little more user friendly. Review collected by and hosted on G2.com.

"Top-Tier Amazon Ad Optimization with Quartile"

4.5/5

What do you like best about Quartile?

I love that Quartile completely handles all of my ads, really optimizing a shaky ads portfolio. I can trust that they will get it right. They seem to have the best technology to optimize listings and revive dead ones. They revived products I thought I would have to discontinue and optimized products that were on the fence. The initial setup was insanely easy. Review collected by and hosted on G2.com.

5/5

What do you like best about Quartile?

I like that Quartile consistently helps us achieve our goals through our partnership. I appreciate that Cesar, our account manager, responds promptly to all of our urgent messages, which is incredibly helpful. The initial setup of Quartile was easy, not difficult at all. Additionally, the difference in performance and expertise compared to the previous agency we worked with is very noticeable. Review collected by and hosted on G2.com.

"Streamlined Ad Management with Excellent Support"

4/5

What do you like best about Quartile?

I appreciate Quartile for its straightforward setup process, backed by a solid onboarding team, which made transitioning easy and efficient. Nick B. stood out with his impressive performance, being readily available for meetings and demonstrating significant expertise in the field. I've found Quartile to be very useful in freeing up my team's time, allowing us to shift our focus from managing ads in-house to other essential projects, making ad management a biweekly task rather than a continuous responsibility. This has saved us time and enhanced our efficiency. I’m also impressed with Quartile’s responsiveness and industry knowledge, as they regularly meet with us and are attentive to our needs and requests. Their support has been crucial in maintaining our advertising goals without overspending. Additionally, the integration with our Amazon account was seamless, taking just a few minutes, which added to our overall positive experience. Quartile seemingly keeps us on the right track towards our goals, with the added benefit of a feature-rich dashboard that, despite my limited exploration time, appears to offer valuable insights. David and Parker have also been very appreciated as we transition into long-term account management Review collected by and hosted on G2.com.

What do you dislike about Quartile?

I wish there was a more seamless transition between our initial representative, Nick, and our long-term representative, David. The handoff seemed planned, but due to out-of-office instances and interruptions, it felt a bit choppy. It's not a major issue but worth noting. Review collected by and hosted on G2.com.

Thank you, Nick, for your thoughtful and detailed review! We’re so glad to hear that your onboarding experience was smooth and that our team—especially Nick, David, and Parker—has made ad management more efficient for you. Your feedback about the handoff process is greatly appreciated, and we’ll use it to make future transitions even smoother. It’s great to know Quartile has helped free up your team’s time while keeping your campaigns performing strong—we look forward to continuing to build on that success together!

"Quartile reduced our ACoS by 33% and account manager is top notch. Highly recommend."

5/5

What do you like best about Quartile?

We've been working with Quartile since late April 2025 and they've been a great partner. We were facing significant increases in ACoS over the past 2 years, so our objective was to rein in ACoS while maintaining TACoS. Over 6 months Quartile was able to help us reduce our ACoS from about 60% to about 40%. We're hoping to get this down even more.

From the get-go integration was very seamless. The onboarding team was top-notch.

Just as important, our account manager Guilherme F has been awesome. He knows our business really well, has smart and on-point insights each week we meet, and generally he feels like a true extension of our team.

We look forward to continuing the partnership. I, for one, am really happy that I can offload a lot of the stress and angst of running an in-house PPC program to a partner like Quartile. Review collected by and hosted on G2.com.

What do you dislike about Quartile?

We were using a self-service automation platform prior to engaging with Quartile, and Quartile is of course much more expensive compared to what we were using before (SellerApp). That being said, Quartile is 100% worth the money, since we weren't reaching our goals under the previous platform.

The Quartile dashboard is good, but could use some UI improvements. For example I wish I could bookmark some oft used dashboard reports. Review collected by and hosted on G2.com.

Thank you for the outstanding review, Tony! We’re thrilled to hear about your impressive results and that Guilherme has been such a strong partner in helping achieve your goals. It’s great to know our platform and team have made a meaningful difference. We truly value your partnership and look forward to driving even greater success together!
