They work VERY hard in optimizing our campaigns, and they have gone above and beyond tracking micro-conversions, which leads to better quality traffic. Any change we've wanted in our campaign has been completed in a matter of days - not weeks. The results have been amazing. We have 4x our monthly traffic, we have improved the quality of traffic, and, most importantly, we are now receiving quality leads and continue to do so. Our traffic is hyper-targeted to our audiences, and I feel we will improve as time goes on.
