QuartileReviews of quartile.com

Quartile has been, by far, the worst ad management company we’ve ever worked with. In just two months, they spent approximately $12,000 on advertising that generated zero sales. Their pricing is based on ad spend, which creates a troubling incentive to increase spending rather than focus on profitable results. Before working with Quartile, our typical monthly ad spend was around $5,000–$10,000. After they took over, they increased spending to approximately $20,000 per month, despite the lack of results. Even more concerning, after I terminated the relationship and cut off the ATI feed to their website, they continued charging us—even after I explicitly told them they were fired. In our experience, Quartile prioritized increasing ad spend and their own fees over generating actual sales. I would strongly recommend that other businesses carefully evaluate the financial incentives and performance results before hiring them.

Not only were these people costly and ineffective at promoting my products on Amazon but they refused to stop charging me when I terminated them.The absolute worst.

Poor performance. Poor Communication. First they restarted producing Google ads without changing anything. They just put their name in the campaign name. This caused ads to stop producing until they could relearn. Then they farmed it out to some guys in another country who rarely communicated, ignoring emails. They didn't understand my business or target market, didn't make any changes to ads or optimize. Then they said that because we had ads already running this was just some sort of review state setup to just monitor ongoing ads. When I complained about the ad rep not responding or optimizing they told me he has a masters degree. I have no idea what that has to do with not actually managing the account. Then I asked for my money back and they refused. Also the rep changed the setting in a campaign to add $ to the revenue when a new customer came from an ad and then claimed we were getting a high ROI when we were not. I brought up these reporting discrepancies with them many times. The person they had me dealing with was in brazil by the way. Emails went unanswered. They had the opportunity to refund me but never did.

Terrible Account Management — Proceed with Caution ★☆☆☆☆ We used Quartile for DSP management on our Amazon advertising account. While the platform itself showed some promise initially, the account management experience was among the worst I've encountered in over a decade of running an e-commerce business. Over the course of our engagement, our assigned account managers failed to show up to two separately scheduled meetings with no advance notice or explanation. Multiple emails — at least three — went completely unanswered over a period of several weeks. When we finally did get a response, Quartile acknowledged they may not have been receiving our messages, yet no one on their team thought to proactively follow up with us during that silence. To make matters worse, we were billed management fees twice within a two-week span. When we raised the issue and filed a dispute with our bank, Quartile's response was not to investigate or resolve the billing concern — it was to immediately terminate our account. They shut down all services and optimizations while still holding a prepaid DSP balance that had not been spent. No effort was made to retain the relationship or address the root cause of our concerns. Instead, we received a boilerplate apology and were shown the door. If you're a small or mid-sized business considering Quartile, understand that once you sign on, accountability appears to be optional. Meetings are missed, emails go unanswered, and if you question a charge, you risk losing your entire account and the optimization work that was done on your behalf. I would not recommend Quartile to any business that values communication, transparency, or basic professionalism from a service provider.

My Account manager Scott was great. Everything else is terrible. Communication for setup is bad, They will bill you even though they miss initial set up. This is the second time I have tried them and has been a waste of time.

horrible company, dont know what they are doing, costs us 10's of thousands in ads with very minimal return. we hired them to improve our ads but we left out of the experience with worse ad campaigns. when i tried to contact them numerous times for a refund but they essentially ghosted me. horrible customer service and i wouldnt work with them again even if they offered me their service for free. they'll try to reply with excuses or "blame" us for their bad execution and results so they come out of it looking good, so dont trust whatever they reply with

We used Quartile for 6 months, and it has been one of the worst PPC management experiences we’ve ever had. Our experience with Quartile has been one of the worst we’ve had with any PPC management platform or agency. 1. They never delivered what was promised During onboarding we were assured that Quartile would improve our PPC, optimize spending, and deliver better results than manual management. After 6 months, none of this happened — our performance declined significantly. 2. Constant overspending without approval Even after repeatedly setting clear daily budgets, Quartile overspent by thousands of dollars, multiple times. This happened throughout all 6 months. Their system simply ignores budget controls, causing huge unnecessary losses. 3. Lack of real PPC knowledge We spoke to multiple people at Quartile, including the “excellence team,” and it became clear that while they understand their software, they lack real-world PPC knowledge. We provided lists of negative search terms that were never added, causing further wasted spend. 4. Poor internal coordination Every time a new team member joined, we had to explain the same issues again. Instead of coordinating internally, they made us repeat everything, showing how disorganized the team is. 5. “System training” excuses for months For 3 months we were told: “It’s early… let the system train… give it more time.” Even after months of data, things only got worse. 6. Refusal to refund despite clear failure We disconnected Quartile completely — meaning they are providing no service — yet they refused a full refund for the month. They hide behind terms & conditions instead of taking responsibility for their own failures. They offered a very small “goodwill refund” which does not cover even a fraction of the damage. 7. Worst service experience in years After 6 months of mismanagement, wasted budget, wrong decisions, lack of PPC understanding, and terrible communication, Quartile has proven to be the worst PPC service we have ever used. We are writing this to help other sellers avoid losing time, money, and patience the way we did.

I rarely leave 1 star reviews, but this one truly deserves it. I stayed for the trial period paying around £500 a month, they were spam calling me for months prior to joining - I should've seen that as a red flag. My account manager was completely clueless about my products & failed to target the right audiences, therefore tanked my ads and wasted a lot of money in the process. Once I mentioned canceling to my account manager, he completely stopped replying to my emails & failed to show up to our meeting, which is the second time. I'm still waiting for them to cancel my subscription & refund me. I had a better experience with Xmars (now Xnurta) and will probably go back to them.
