My team at Quartile is world class at their craft, they spent serious time going over my unique and intense advertising with over 8,000 Ads. Currently they have cut my ACOS by almost 50% and continue to fine tune Ad sales while also increasing organic sales and keyword positioning. A+ service.

Ever since I began using Quartile for my amazon ads strategies, I have found nothing but success and skill from this team of experts. My campaigns have pulled 180* from where we were prior, and I can say I will never be going back.

Quartile has made my life so much easier! I am an artist and selling my handmade goods has never been my forte. I love to paint and craft. Not spend hours on my computer analyzing data and making SEO-based decisions. That's where Quartile has come in. After a referral from a fellow artist, I decided to check Quartile out. As someone else who is in the art business and not the data analysis business, this person told me how much easier it is to boost your e-commerce sales while also spending more time behind the paint brush and less in front of the laptop. Sure, I sell items on Etsy, but there's so many other marketplaces that I am now able to take advantage of. I never thought I would have the know-how to take advantage of Amazon Seller Central, Google Shopping, Instacart, and Shopify. Now I do! I highly recommend that anyone who is seeking to sell but doesn't want to become an IT specialist in the meantime try this product!

Kimberly, thank you for the review - we're happy that Quartile allows you to focus on creating art! Our data scientists would probably find a lot of common ground with you; they are very passionate about their analysis, algorithms, and insights, but instead of paint and brushes, they use data and code.

Quartile has helped immensely with my retail efforts. The integrations with Amazon Seller, Google Shopping, and Shopify are convenient and easy-to-use, which has visibly brought down our ad costs and improved overall campaign management. Results were seen less than a couple of months into use, so we're curious to see how much more Quartile will help out with our PPC efforts. If you're skeptical or have had a bad experience with Quartile in the past, I'd suggest giving it a bit more time. Ad campaigns don't explode overnight, often taking weeks if not months to make a significant impact. Some products or services simply take more time for noticeable results to ensue. I'll continue to use Quartile as long as the progression is as positive as it's proven to be thus far!

Quartile provided horrible customer serivce. Their rep was totally incompetent and had no idea what he was doing. When I kept asking for a refund, he wouldn't even attempt to speak to his boss. I asked for a new rep and he wouldn't forward me to a new one. I told him to cancel my account and they have been charging me for the last three months.
