When writing long copy it should always be a dialogue. Copywriting is communicating. Don't write too much about "I" "we" "our company" etc. No-one is interested in your business or mine. Prospects are very interested in what your business can do for them. Focus on the prospect with words like "You" and "your".
I am about to set up a clothing label, is there any website links or info available for people setting up a business for the first time? Also i`ve been told about a type of copywrite where you can post everything you want to be copywritten to yourself through recorded delivery, is this true?
