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!

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.

Total Disappointment I used Quartile before Covid and they were very effective. I have run my own Amazon PPC for a while and had ACOS running at around 40%. I went back to quartile in order to try and bring down my ACOS and increase sales. They were confident that they could bring my ACOS down into the 20% range but said that they expected it to take a month or two before their algorithm really kicked in. I used them for a total of 5 months and, during that time, my ACOS hovered around the 70-80% mark. We had weekly meetings at which I begged them to bring down the ACOS as I was simply losing money on every sale. They constantly promised to do so but month 5 had ACOS running at 75%. I gave notice and stopped using them. They ignored the notice I'd given them and continued to charge me after termination of contract. I am so disappointed with the results I got from them and cannot believe the way that they treated me after termination. This was a company who's AI algorithm might have worked in the past but obviously cannot cope with the way Amazon currently runs its advertising. Losing me thousands of $ was bad enough but then the way I was treated afterwards was appalling. I certainly would never recommend them again and would strongly suggest that potential customers look elsewhere.

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

Great experience, results, and communication I've been very happy with Quartile so far. Using them for about 6 months now. We began utilizing Quartile for the Amazon side of my business and were impressed by the results. Not only did we see a lift in sales, but it actually helped us become more profitable at the same time. After seeing those results, we just finished up a 3 month test period utilizing their Google Ads service and we are just as pleased. I have always had bad experiences with third party services, but I will say Quartile has impressed me. Its taken a lot of work off of my plate, and improved our performance. Communication with my account reps is quick and easy. Overall very happy with my decision to try out Quartile and would recommend their services to other businesses looking to elevate their PPC strategies.
