Good copy is readable, maybe even enjoyable, and probably free of spelling errors, grammatical snafus and typos. But it’s not going to win you customers (though it might show Google your website still has a pulse, which isn’t nothing). Great copy is the kind of thing people talk about and share with their friends. Great copy makes the rounds on Twitter and Facebook, garners high page views, and contributes something of genuine value to the world – or it’s just really, really funny.
But I’m not here to talk about good copy, or even great copy. I want to talk about a very specific kind of copy: Conversion copy.
