Writing content for websites, articles or copy is all about the message. A message has to have two things. First, it has to have the voice and the authority of the one who sent it. Second, it has to have a receiver for whom the message is intended.
Good communicative writing takes this in mind. Whether for my niche sector or any other client, the content I write aims to put the sender and receiver together. You the client, connecting with your audience. Writing content is all about respecting the message.
