Andrew Girdwood is "digital marketing, search, gaming geek". Aren't you? Why not?
He works for a successful search engine optimisation and digital marketing agency and they have nothing at all to do with his blogging. Everything here is personal opinion.
Andrew has lots of opinions. Even when people don't want Andrew to have opinions - he still has opinions. Andrew doesn't expect everyone to agree with him and therefore welcomes constructive criticisms in his blog comments as much as he appreciates valuable insights and observations.
