We originally discovered 1SEO when we were searching for a local company to service our truck fleet. The 'local' company was 45 minutes away but at the top of the search engines! We were SO impressed, that we just HAD to ask that company who was managing their advertising and they RAVED about 1SEO. Since we had already seen the performance results through our own experience, we connected with 1SEO immediately.Our small, privately owned company has been in business for 20 years. We've seen every sales pitch, and met with hundreds of people claiming they would increase our business and perform miracles. We are happy to save you the time, headaches and money by telling you that 1SEO TRULY delivers! You have full access to the performance results on a DAILY basis! No smoke & mirrors. Everything is shared with you in easy to understand reports. They provide you full control on managing your advertising campaigns but at the same time, they will take the wheel if you don't have the time. Most importantly, they have a huge team and every member of their team is creative, intelligent and as excited about your company as you are! In addition to handling our SEO business, they created a new website for us and continually design new content to keep our company and fresh AND profitable! 1SEO literally provides you an entire marketing and advertising division of your company without the payroll cost!

This review is way overdue - hiring 1SEO to bring our 50+ year old, family owned, small business into the 21 century was the BEST decision we've ever made. Google advertising and website design is made 100x easier when you have a team of experts on your side. These ladies and gentlemen are phenomenally helpful and the best at what they do. Andrew Foligno is super helpful, responsive and insightful. Honestly, I can't believe how well 1SEO brings in new leeds and much higher ranking within Google's search results. Any small\medium sized business will 100% benefit from their services.10 stars!

1SEO is great! We're not a large business, but that doesn't matter. Big or small 1SEO helps us all with the same level of attention. Lance has managed to create a wonderful team of professionals, from the sales, to implementation, and ongoing support. The world of marketing has changed so much from the days when you would place a newspaper or radio ad and cross your fingers. The world is digital- it's in everything that we do. At 55 yrs old I need help with this stuff! The way to reach clients is digital, and these guys know what they are doing to make the most of my advertising dollars. Not to mention the fun they create! They walked us through the entire process and were always available to us.

1SEO has optimized and streamlined our website to deliver a cleaner, far more user friendly experience. The new chat feature that was implemented has made the process of capturing leads much more efficient allowing a more prompt response. There are even more changes in the works so I am excited to see what else the team has in store. From the initial contact with Bernie to everyone on the onboarding team, everyone at 1SEO has been exceptional. Especially the Director, Kathy Donohue, she is the absolute best. She is always so attentive and just a pleasure to work with. She has gone above and beyond countless times to ensure that I was getting everything I needed and that we were being very well taken care of. If your business is in need of expert digital marketing services I highly recommend 1SEO.Rod Allen, OwnerINFINITE MOVING

1SEO's service has been largely very good and we are pleased with the results our company has been seeing. Specifically, I have had a great experience working with Michael Doane as our company's account manager. I appreciate Michael's attention to detail and the regular check-in's he offers to go over relevant metrics. For someone like myself who knows nothing about SEO, this is incredibly valuable and reassuring!
