      Digitalhound have been our go-to agency for a number of years now. After having done a thorough evaluation for a suitable digital marketing agency in London, we were pleasantly surprised by how quickly their team got to grips with our brand aims, technical project requirements and demanding timescales.Proactive in their approach, they are a dedicated team of exerts who constantly strive to advise and deliver above expectations with clear communication lines and timely report breakdowns. Suffice to say, we are absolutely delighted with the results they produce for us time and time again and we see this is a long term partnership for the foreseeable future.

      To our surprise the team at Digitalhound.co.uk have already hit many no.1 spots on Google for some of our primary keywords in such a short period of just 5 months. These top search rankings has brought us more site visitors and sales and I am really excited about what they will achieve for us in the near future.I would strongly recommend Digitalhound.co.uk to anyone who is looking to build and grow their brand presence online.

      Zack Elias's Review Sourced from Google

      Relevance is amazing! Once our non-compete ended with our previous company, we jumped right over to Relevance and the difference was noticeable day 1! Our account reps, Kari, Janine, and Chanelle, are caring, thorough, creative, and fun. They are also very well connected and tend to get us terrific media exposure. They always go beyond the call of duty to ensure that our needs are met and that we are happy.I would highly recommend Relevance to anyone in need of professional PR.

      The Social Golfer's Review Sourced from Google

      I keep getting demanding emails from this company regards their client page on our website but they don't seem to respond to my emails responses. Instead they just keep spamming my inbox. Their website does not have a contact no. (??) and the no. given on this page doesn't work either(?) And the person emailing me doesn't give a contact no. e.g. Jeanna? So not very professional. I've reported this to their client HQ too, as I am getting fed up with the daily emails and no one gets back to me, so I am now resorting to leaving a bad review here. In the hope someone at this agency bothers to to pick it up. Ian - Editor - The Social Golfer
