Just make sure that the e-book builds on your blog output—don’t simply rehash what they have already seen! After all, these people are now paying customers and will get upset with old information. Later on, as you become more established and your archived material becomes more extensive, you can poll your readers to learn what topics they’d be interested in learning more about and interested in purchasing.
