Highest Recommendations We partnered with Quartile over 2 years ago on our Amazon US account and have since added multiple other channels because of the growth we have seen with the use of their AI technology. The team is so easy to work with always willing to pivot and make adjustments to help us meet our goals. Highest recommendations!

Absolute game-changer for us Partnering with Quartile has been an absolute game-changer for us. These folks are wizards with Amazon ads, wielding their AI and machine learning like nobody's business. What's amazing is how effortless the collaboration feels. They plug into our systems, and voilà - our joint campaigns just take off, smarter and more efficient every day.

A year of great results I’ve been working with Quartile for almost a year now and I couldn’t be happier with the results. I’ve seen consistent improvement with my campaigns. The account team that I work with is prompt and very knowledgeable. Give it a shot, you won’t regret it.

The algorithm is a black box The algorithm is a black box. You don’t know why bids are changing or which campaigns/products were going to be pushed aggressively. Everyday was a surprise to see what products had a disproportionate amount of ad spend for the previous day. I couldn’t effectively manage the algorithm based on my products margins and inventory position. Sometimes the algorithm would stop spending on certain campaigns altogether by reducing bids to 2 cents. I had to relaunch those campaigns. By the end I was spending similar amount of time trying to manage the algorithm as I did on managing my PPC before.

Easy to learn and use, helped us scale fast We started using Quartile in July (5 months ago) and it has worked so well for us. We had previously been managing individual campaigns on Amazon manually in the advertising console. Quartile's software is pretty easy to use and has helped us scale fast and lower our ad costs.
