My company has been using Quartile for… My company has been using Quartile for a long time. But lately, its bidding feature isn't working properly. Spending money on it now might be a waste because it's not delivering results. They made the cancellation process harder as well. I strongly recommend not using Quartile. It will cost you a lot of money.

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

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.
