Why would you want to lose your reader's attention by sending them to another page? That kills how much you sell with that ad. The prospect may choose to learn more about your ad, but you don't want to lose their attention like that. Getting a half-sold prospect out of your page is just losing a customer. Just look at an informercial for example, the copy can easily take over an hour of narration. Also, widespread testing of ads has been done for a very long time, it's not like research in marketing has never been done before. Long-copy always sells more than short copy. The trick is to write long copy well, which is not something that everyone can do.
