“It depends”.
Ask most copywriters how much copy you need to sell your shizzle and that is what you’ll hear.
It’s correct, but it’s also like being a UFC fighter with good penmanship – it’s no use whatsoever.
Truth is, there IS a “right” amount of copy.
Doesn’t matter if you’re selling a product, service, or your (or anyone else’s) body.
Here’s a good way to think about it:
In order to click the “buy” button, your customers need to know and believe some stuff.
The amount, and type of “stuff” will vary from business to business, but all customers need to know stuff before they click “buy”.
You’re mission, should you choose to accept it (and if you wanna sell shizzle, you probably should) is to create copy that serves up everything they need to know.
So, don’t worry about how long yours is.
Worry about your customers – think about what they need to know and believe to get from where they are to “Hell yes! I’m in”!
THAT’S how much copy you need.
