Insights and Strategy I have had a great experience working with Quartile for my Amazon Advertising needs. My Account Manager is knowledgeable, actively monitors the account and is always on top of things. On our biweekly calls, I receive valuable insights and strategy recommendations that have helped us to grow our core business and launch new products with excellence.

Communication is key. Ever since I started working with Everton Konrad at Quartile, I've felt like I can reach out anytime with any question. Everton is quick to respond. I can't say this is always my experience with all companies I work with. He is also consistently analyzing our account and helping us achieve the best results with the least amount of ad spend. I would highly recommend working with Everton Konrad at Quartile.

Amazing As an agency, we’ve tried a bunch of different bid optimization tools, but Quartile is on another level! Their AI actually does what it promises. Our ad game has seriously leveled up since we teamed up with them. Plus, their crew is super cool and always on the ball. For agencies looking to step up their game, Quartile's worth checking out!

Poor performance and Fraudulent… Poor performance and Fraudulent transaction. I tried Quartile for Amazon PPC maintenance. I was offered 50% discount for first three month with no contract and I was told I can cancel anytime. After wasting one month and £500 and lots of sale I decided not to continue however I was surprised when I was charged another £500 for second month without my consent. I was shocked how they got access to my card detail. I only made payment once at the beginning of first month with the link provided by quartile however I didn’t enter my card detail it took money directly from my bank. But again when I was charged at the beginning second month I contacted them to cancel which they did but told me there will be no refund for money as you need to give us 30 days notice. Dear I didn’t use your service I tried you for first month and I do not like your performance so I do not want to continue for second month. How can I give you notice of 30days before even trying you for first 30 days. This company is a fraud as you signup their portal will take two days weeks to import data from your Amazon account and then they will start working on campaigns so they will launch first campaign after 20 days of subscription. The performance is very poor please do not signup with them. You will get 100s of email and phone call when you signing up and then there they will contact you once a week so there is no communication and you can’t get hold of them specially if you are not based in USA. however if you decide to cancel the subscription you will be charge for the whole month in advance and no one will respond your email. God bless you all stay away from gold digger

Stayyyy Awayyyy Stayyyy Awayyyy, unfortunately they like many other Roomie companies will tell you it takes at least 2 months for results. So their trick is since they have a 3 month contract they figure by the time your done paying them the monthly fee you can cancel service and they just pocketed your fee and wasted your hard earned money on budget. BEAWARE they Outsource Out of the Country to Brazil and cheap countries so they can pay cheap labour and use people that barely speak English. SCAM SCAM SCAMMMM
