Overflow and Jeff have been our friends for 12 very successful years. During those years, we have gone from nowhere to everywhere online. Our keyword rankings and traffic have been exponentially improving in a very competitive part. We kicked it off with a meeting where they got to know the nature of our business and our expectations. We started a comprehensive plan which we have followed since, plus some fine-tuning for all the algorithm updates. They have always treated us like a valued client. I find them to be very knowledgeable, welcoming, and patient, and they are always open to discuss new ideas. They are always guiding me through the complexities but most importantly they deliver great results!
