“From the moment we met, to the moment we ran our first campaign, to the moment we quadrupled our sales with their help and expertise, Sum Digital has been exceptional to work with and an intricate part of our marketing strategy.”

“In the constantly changing paid advertising space, Sum Digital stays ahead of the curve to consistently generate return. They’ve helped our leads grow exponentially, get direct-to-customer advertising, are incredibly refreshing to work with, and I can’t recommend them highly enough.”

“It’s so incredibly refreshing working with an agency that gets direct-to-consumer advertising yet is so humble. We’ve worked with “gurus” and some of the big names in e-commerce advertising and it was just so complicated and unproductive. Working with Terry and Joey and the Sum Digital team is a breath of fresh air and the results are 2X what we were getting from our prior agency.”

“Sum Digital and Terry and Deirdre specifically care about their clients - when you come on with them they take the time to understand your business, learn your customer base and work with you 24/7 to find ways to improve ROAS while staying true to your brand for the long haul. You have a question, it is 9pm, no worries - they are working. They have allowed us to get to a new level of our business that we didn’t know was possible. ”

“In the constantly changing paid advertising space, Sum Digital has done exceptionally well to stay ahead of the curve and consistently generate return for my company. They’ve helped my business grow exponentially and I can’t recommend them highly enough.”

“Terry and team audited our FB Ads account and their subsequent specific insights helped us achieve significant, sustained gains in our program – without any formal engagement.”

“Sum Digital has been a great asset to our company for several years now. We’re very happy with all of the work they do managing our paid search campaigns and the results have been consistently excellent and still improving. They are a pleasure to work with and lend their insight... to all parts of the business.”

“Terry is a valued contributor to our team, and his work has substantially improved our performance in paid search. He is a proactive problem-solver who achieves quick and remarkable results. I am impressed with both his skill and the breadth of his knowledge. Plus, his enthusiasm for Internet marketing makes for a fun and productive working relationship.”

“Terry Whalen is among the most knowledgeable PPC experts I have ever met. His iterative approach to campaign management including testing and expansion has delivered tremendous and lasting value to clients over time.”

“I have launched and grown multiple companies with Sum Digital. They’re willingness to listen, to execute and to provide strategic insights is an invaluable asset for any marketing team.”

“Terry took over an SEM program that was spending a lot of money but not getting a lot of results. He brought structure and visibility into our SEM activities, as well as his expertise in conversion funnels, landing pages, ad text and keyword development. Our company was undergoing a lot of changes with respect to the lending market, and Terry was quick to act on these changes. I came to think of Sum Digital as more than just our SEM agency – they really acted as part of our internal marketing team.”

“We hired Sum Digital shortly after running an unsuccessful trial with a leading PPC bid optimization provider. Once we said “Go” they were able to quickly hit the ground running and achieved fantastic results in a very short period of time. In the first month they took over they were able to blow away our growth estimates... I would highly recommend Sum Digital to anyone who is looking for a paid search agency or anyone who may be questioning if they are getting all they can out of their current paid search efforts.”

“Terry and Joey at Sum Digital are great to work with and they continue to help take our PPC campaigns to the next level. They are always on the lookout for areas of improvement and other Paid Search opportunities to allow our company to succeed. These guys are top notch and continue to teach me how to better manage the accounts. I definitely recommend Sum Digital to anyone looking to increase their online marketing efforts.
”

“Sum Digital is my go to group for SEM campaigns. Having worked with them for the past 3 years, I can, without a doubt, say that they are the best. Not only does Terry and his team do a great job at managing the overall process, but they take the time to educate and inform myself and my team. I have, and will continue to recommend Sum Digital to anyone.”

“Joey and Terry are phenomenal to work with. I have now worked with them at three companies and have been impressed every step of the way. Not only do they deliver great results - we had drastic increases in conversion while decreasing costs per conversion - they take the time to share their knowledge. Thanks Joey & Terry!
”

“Terry is fantastic. Our SEM has improved exponentially from Day 1. Terry takes the time to understand the behaviors that you’re trying to drive and why they’re important to you. Hes able to bat around ideas, build on previous campaigns, and discuss your overall strategy as though hes sitting with you in the office each day. And hes just as reachable too. I can think of a couple of times when I’ve sent him a 7am e-mail, only to hear my phone ring 30 seconds later. That’s fantastic service.”
