I strongly suggest that you stick with writing Self-interest headlines. They are the most effective, so use them. News and curiosity headlines are good but should only be attempted by experienced copywriters and carefully tested. A curiosity headline can be a winner but the down side is that it doesn't actually offer a benefit. Very good body copy needs to accompany a curiosity headline.
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?
