"Quick responses and insightful reporting"
4/5
What do you like best about Quartile?

Thorough and insightful reporting on regular intervals that gives our team numbers to back important decisions. Review collected by and hosted on G2.com.

What do you dislike about Quartile?

No dislikes come to mind. We've run into some feed and spend issues but when we bring them up they are typically resolved quickly. Maybe a way to get notifications when sudden changes in product feeds or spending occurs to make sure it's taken care of promptly. Review collected by and hosted on G2.com.

"Avoid Quartile: Lame Billing Policies and Poor Performance"
0/5
What do you like best about Quartile?

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. Review collected by and hosted on G2.com.

What do you dislike about Quartile?

Our company started working with Quartile in March 2024, optimistic that their services would help drive growth for our Amazon product sales. We had bi-weekly check-ins with an account manager, expecting results. Unfortunately, our experience with Quartile fell far short of expectations.

Throughout 2024, our Amazon product sales stayed completely flat month-to-month. Compared to 2023, there was literally zero improvement in revenue. Despite the ongoing stagnation, Quartile did not offer any actionable strategies or meaningful insights to move the needle. After months of lackluster results and no return on our investment, we decided to cancel our service.

Here’s where things got even worse:

We canceled a full week before the start of the next billing cycle, assuming this would end our partnership cleanly. Instead, Quartile informed us of their 30-day notice requirement hidden in the fine print of their contract. This policy meant we were charged for an additional month of service—despite the fact that no services were rendered, nor were they needed.

Quartile refused to negotiate or make exceptions, citing "policy" as the reason. This rigid and customer-unfriendly approach adds insult to injury for a service that failed to deliver results in the first place.

To anyone considering Quartile:

* Be prepared to comb through their fine print, as their policies will penalize you even if their services don’t work as promised.

* Don’t expect flexibility or fairness if you decide to cancel.

* In our experience, you could end up paying for absolutely nothing.

I wouldn’t recommend Quartile to anyone serious about improving their business. Proceed with caution, and make sure you understand what you’re signing up for because they certainly won’t prioritize your success—or satisfaction. Review collected by and hosted on G2.com.

Response from Michael Ianniello of Quartile

Brandon, we’re disappointed to see this review, especially since we’ve attempted to reach out and resolve your concerns, but you’ve been unresponsive. We always strive to work toward an amicable solution. Please reach out to us directly—we’d still like the opportunity to work toward a resolution.

"Amazing Growth"

5/5
What do you like best about Quartile?

Our company has been with Quartile for around a year now, and has seen clear results of their knowledge and ease of implementation of their new campaigns. Renan, our account representative, is constantly fine-tuning our campaigns to maximize return. Review collected by and hosted on G2.com.

What do you dislike about Quartile?

Quartile is great, but the fact that Google Ads is so confusing to use on its own and requires experts like Quartile's employees to use is our dislike. Review collected by and hosted on G2.com.
