Write a Profitable Copy
First of all, your copy is not the place to be bragging about yourself. You have to turn your attention to the people who will be buying your product, your customers. No matter what virtues you may possess, this is much less interesting to your prospects than how your product can help them. They are only interested in what your offer means to them. People have a short attention span when it comes to hearing about someone else's greatness, so going on about this will only cause your readers to leave your page. Remember, when writing copy, "you" is a much more powerful word to use than "I." Copywriters who talk about themselves too much end up driving their prospects to the web pages of their competitors. Don't wait too long to show them what you've got for them. Your reader should have center stage all through your copy.
You don' t have to create copy that sounds like you teach English for a living. You are merely attempting to tell your prospects that your products are necessary. Instead of making them impressed with your language skills, just speak to them clearly. Just communicate like you would with someone you knew. The more ease you put into your writing, the more confidence you'll convey. You want your prospects to form relationships with you. If you can create an understanding about your products, your prospects will receive your copy better. Think of your sales copy as your own sales person. Sales copy that sounds too sales-like will turn your readers off and they won't want to buy what you're selling.
Another copywriting principle is that you should be as specific as possible. You should use this in all of your copy, from the headline to the sub headlines to the entire body. Generalities don't tell people what they want to know about a product. The trick to influencing people is to supply specific information that to into depth about a subject. It makes your copy more believable and increases the trust factor. Unless there's a good reason to do otherwise, you should avoid vagueness and provide specifics about your subject. So you have to keep a number of factors in mind if you want to write good sales copy. Getting them all right would take a great deal of time and understanding. Be patient and keep working on it and your copywriting will improve over time.
