Save your ebook as a PDF and then put it in a zip file. You will have to be familiar with an FTP program to upload it to GoDaddy’s server (although you may be able to do it through their cPanel). Once you have the zip file on the server, just create a link using an a tag like you would any other link.
It would look like this,
<a href=”http://www.example.com/the_path_to_your_zip_file.zip” >Your Download Link</a>
Hope that helps,
