They were great, you could take them with you and put them on shelves and they do still exist and will continue to for the foreseeable future but the time of the E-book has arrived.
The marketing E-book is a slightly different animal from just an E-book. Marketing E-books contain text, images, links to web pages and navigation controls. The marketing E-book has become a very important part of marketing on the Internet.
With a marketing E-book you can present your story in an effective way and include links to your web sales pages. Your E-book can become your best salesman.
First, your E-book needs to be interesting and informative. It always has links back to your web site and to your sales page.
Next, be sure that you have a prominent section telling readers that they are free to give your E-book away. Let them know that they can post it on their site as a free download, that they can use it as a bonus, and that they can bundle it with other products. This is the way to create viral marketing for your products or services. Remember those links back to your site contained in the E-book?
Last but certainly not least before you send your E-book out to the world, double check spelling and grammar and be sure that you have tested every link to verify that it goes where it is supposed to go. Obvious errors will reflect badly on you and will not be of much value to you, it could even by damaging.
Post your E-book to some of the E-book directories. Many let you post it for free, or will let you post a link on their site to your E-book.
