Thanks so much, Greg! We're glad to hear the onboarding team made a strong impression with their responsiveness and hands-on support. We are looking forward to continuing the partnership!
Quartile’s automation has streamlined our bid management and keyword harvesting. Since onboarding, we’ve seen consistent improvements in ROAS, ACOS, and overall campaign efficiency, and we’re already on track to reach our sales goals. Our CSMs are friendly, responsive, and highly professional—they keep us informed with detailed weekly updates.

Two Quartile ad experts took my account and surprisingly and so quickly transformed it into a winning marking strategy.

We're excited to see your improved sales—and even more excited to keep building on that momentum with you!
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.

Thank you for sharing your feedback. We’re very sorry to hear there was a communication breakdown during your trial period. That’s not the level of service we strive to provide, and we understand how frustrating that must have been. Our discounted trial period is specifically designed to give new clients an opportunity to evaluate the platform and begin optimizing campaigns. However, due to the nature of data-driven advertising, it can sometimes take more than a few weeks to see consistent, scalable results. We wish we had the full opportunity to complete the trial and make the necessary adjustments to move toward your goals. We’re escalating this case to a director, who will be reaching out shortly to gather more information and work toward resolving the issue.
We've appreciated the support and insights provided by the Quartile team. Mariana, in particular, has been an outstanding point of contact — she's responsive, knowledgeable, and genuinely invested in our success. The platform’s automation has helped streamline our Amazon PPC efforts, and the regular check-ins keep us aligned. We’d love to see even more proactive insights based on performance trends and clearer attribution of how specific optimizations impact our results. Overall, it’s been a strong partnership, and we’re excited to keep building on it.
