Meet Our Satisfied Clients

Michael Ferrari
CMO, Crown Media Tech
Been working with SEO.co for the past couple years and we are thrilled with the output and turnaround. We gained TRUE competitive advantage in the industry. Communication has been excellent. World class at what they do!

DeAnna Andrews
Product Marketing, Chegg Inc.
After working with another company without seeing any results, SEO.co took over our website and search engine optimization and we couldn’t be more pleased! Samuel Edwards is truly a master of his craft. After a full audit we left with tangible results of their work that made what we paid well worth it, one thousand times over. We would never go anywhere else after the experience we had here.

Geoff Lilienfeld
Partner, RPI Consultants
These guys are great to work with. Very high writing quality and very well organized.

Heiko Tröster
Head of Marketing, Datapine
I work with them together several years and I am supper happy with their services. Their method of operating is really effective & professional.

Ken Shenkman
CEO, Bulk Candy Store
I have worked with several PPC & SEO companies in the past and I can unequivocally state that SEO.co is by far the best. While many other firms do not do (or are not capable of doing) what they promise, SEO.co does. They also stick with you - other agencies put you on a "set you and forget you" path, but not these guys. They provide frequent updates and feedback to make sure they are doing the best they can for you. I have used them for paid advertising and link building and have been very satisfied with both. I highly recommend them.

Sophia Paul
Regional Recruiter, Freedom Mortgage
SEO.co is a phenomenal company that cares about its clients. I have worked with them on multiple projects, and to say I am satisfied with their work would be an understatement. SEO.co is a marketing firm that truly understands SEO & PPC and the other facets of marketing. They have helped me optimize my website, receive a higher score on Google, and taught me different ways to target my demographic. I highly recommend them for small businesses and corporations.

Brenton Clive
Director of Marketing and Business Development, Northbay Products
They seem to really care about their clients. They aren't only doing a great job writing articles for blog posts linking to our website, but they are writing great blog posts for our own website. Plus, they have given great insight as to how we can improve the on-site SEO to help us in every aspect of ranking well on Google. Overall, we've been very pleased with the work that we've gotten and have felt the value has exceeded the costs.

VentureX
We have been using SEO.co for nearly two years now and couldn't be more satisfied with the quality work they produce. Their SEO / PPC management has driven quality leads for our business and new clients. We will continue to use SEO.co and recommend them to local businesses like ours.
A Strict Adherence to Client Confidentiality
We highly regard the privacy of our clients, including household brands as well as other online marketing agencies who serve them. With only a few rare exceptions where clients have allowed us to provide direct case studies, we do not directly list or promote past client engagements on our website.
If you are interested in discussing past client engagements and successes or would like direct access to select case studies, please get in touch via the form at right or give us a call.
