We spent week’s looking for an SEO agency but they all looked the same. HarperSEO was referred to us via a very senior digital publishing contact and they have been perfect. They work directly with our web developers, use their own initiative to get things done and they don’t waste time telling us stuff we don’t need to know (unless we ask them!)

I have worked with HarperSEO on a number of SEO projects and they've demonstrated a high level of technical competency and are able to work independently and to tight deadlines. I wouldn't hesitate to recommend them as consultants for SEO related work.
