I've had an outstanding experience working with Quartile, particularly with our account representative Everton, who has been instrumental in optimizing our Amazon store's marketing performance. The results have been remarkable - we've seen a significant reduction in our Advertising Cost of Sale (ACOS) while simultaneously achieving higher sales volumes. What sets Everton apart is his ability to make our marketing strategy more efficient and cost-effective. He has demonstrated a deep understanding of Amazon's marketplace dynamics and has consistently implemented data-driven optimizations that have improved our campaign performance. The impact on our business has been substantial. Through Quartile's platform and Everton's expertise, we've been able to: Optimize our advertising spend more effectively Increase our overall sales volume Improve our marketing efficiency across campaigns Better understand our performance metrics and opportunities for growth I particularly appreciate how Everton has taken the time to understand our business goals and tailor solutions specifically to our needs. His proactive approach and attention to detail have made him a valuable partner in our e-commerce success. If you're looking to improve your Amazon store's performance and work with a team that delivers results, I highly recommend Quartile and specifically working with Everton. They've proven to be an invaluable asset to our business growth strategy.

They are great at answering any of my questions while also providing educated insights on our ads. When I ask for solutions they provide me with multiple options instead of a single answer which is great. Getting started with them was easy and every time I reach out to my account rep Cris, he get's back to me very quickly.

We worked with Quartile for about 10 months and liked the quick onboarding and bi-weekly status updates. Unfortunately we didn't see any improvement in results in our Amazon business.
