      Digital Marketing Review from George de La Portilla

      I am really happy with the Digicorns team, I recently relaunched my website and gave them absolutely no notice of what is a critical and potentially disastrous SEO change. To their credit they just stepped in and made it happen with no fuss - making sure every box that needed to be ticked happened in just a couple of days to make sure I didn't fall off the face of Google. Since then things have continued to impress with my rankings for keywords (ones I actually value, not some rubbish no one uses) climbing month on month - some even in position 1 or 2. Congratulations to Digicorns for the wonderful team!!

      Web Design Review from Kevin WADE

      Do not use these folks!!! We paid them the fees for multiple years to keep our Website Domain current. They did not pay the Webhosting Company HostGator after the 1st year. Now they are refusing to refund our money and stopped answering emails and calls because we would not give them any more funds. RUN AWAY FROM THESE SCAMMERS!!!
