1SEO has just started helping me build my brand to grow my singing and music lesson business and so far I am very happy. The staff is amazing and communicative about the entire process. Kathy has been especially helpful and always responds super quickly and helps me communicate what changes and updates needs to be done to the team working on my seo and social media campaign. I’ve started receiving an increase in leads and the leads are getting to be very good quality. It’s only been 3 months and I’m looking forward to the future with 1SEO helping to expand my business!

It has been a great experience to be working with 1SEO.We have been in business for over 20 years and we realized that word of mouth is not enough to grow our business. Therefore, we were looking for alternative ways to boost our sales. Then, our friend Greg from Made To Last Visual referred 1SEO to us.We are completely satisfied with 1SEO's expertise and professionalism. From Josh to Sam and Christopher our experience has been excellent. Additionally, Kathy is great, she is very helpful and always provides answers to all our questions. We are glad we came across 1SEO and look forward to bringing more sales and doing more business with 1SEO.

Well, I have to be honest. I was VERY hesitant to sign on with another seo company after I had a poor experience with company from CA. After, talking with 1SEO and them being a local business, I decided to give them a try. I liked that they were month to month, with no contract.I did my due diligence and they also told me, that seo doesn’t happen immediately. It will take a few months until I start seeing “my investment” starting to work. The first couple of months, involved setting up, strategizing, filling out the questionnaires and so forth. Once I approved it all, the new site went live.We didn’t see much activity at first, which is always disappointing even though you expect it. But as the months went on, you could see an improvement in website visits, calls, visits, activity and increased sales.Literally everyone I have dealt with has been on top of their game. From initial intro call to the monthly follow-ups. It’s been great to be able to see the progress online.As is good business, I was initially asked to write a review early on. I like to wait so I can write a thorough review. As a small business owner, I want to make sure my money is being invested in marketing that works. If I was to write a review in the first month, it wouldn’t have been fair as I knew it wasn’t going to have an immediate impact, so what would I have written?!? So, instead, I waited several months to see the progress, so another small business considering doing business with 1SEO can get a fuller picture.For anyone considering seo, ppc, etc, I would contact 1SEO. They are a small business, local and know their stuff.

We have more qualified leads come through and our phones have had a large increase coming in. The most important aspect of all of this is they really treat me like we are family. I have developed a true partnership with them and I am looking forward to continuing to grow and work with them. If anyone is looking for a top notch marketing company that is NOT just an agency then 1SEO is the one for you. They have helped me grow, let them help you as well!

1SEO is by far one of the most thorough and professional groups of people I have ever had the pleasure of working with. Shauna C specifically has been of incredible help and is one of the most dedicated professionals I have ever worked with. She goes above and beyond what you would expect and continuously follows up until the job is completed to your standards. She is an absolute BEAST!! I wouldn't trust ANYONE or ANY OTHER company to handle our needs for our company.

My experience with 1SEO for the past 4 months has been positive on many levels. I have contracted several different vendors and consultants over the years with everything from SEO to Google Ads, Facebook marketing etc. Its just not easy to develop skills across the board in these arenas, so I am glad to be working with an operation that has resource's at different levels that can provide expert level consultation and execution to make all of this come together. Looking forward to continuing our work with them as long term.

We started working with 1SEO around a year and a half ago with the goal of improving traffic to our website and online enrollment into our service. 1SEO’s team hit the ground running, taking a deep dive into our business and competitive landscape. I was immediately impressed with the level of information and sophistication of the insights they provided which were extremely valuable and have helped us noticeably increase our organic traffic as well as the user experience on our site. After the initial setup phase, we rolled out our first digital campaign, and so far, we are thrilled with the results! We intend to expand our campaign to other areas of our business. I can’t say enough about the 1SEO team. All of their staff have been knowledgeable and just overall great to work with!
