The team at result calls was very responsive, helpful in explaining what they were doing for me (and why) as well as providing great advice when I had questions about my account or results of different changes we made over time! They also have an incredible support network with multiple people who are always willing/able to jump right into helping you out if need be - no matter how early / late it may happen during business hours!! Nothing really but all around awesome service from start to finish. If your looking for someone not only knowledgeable within GBM's specific area, but extremely personable & professional then look here first! There aren't many companies where everyone involved has such high levels of expertise across so much industries which makes working together seamless.
