1. Build up anticipation for your ebook release on all your social networking platforms. You can even host a virtual book launch where you can offer potential buyers a discount for attending and "bringing" a friend. Don't forget to remind your buyers to leave you a review. Reviews are an excellent source of valuable, free marketing.
2. If you've created an entire website for your ebook, make sure that the URL or domain name incorporates keywords, vs the actual name of the book. For potential buyers who don't know about you or your publication, keep in mind that they will search for keywords that are relevant to your publication, as opposed to the actual ebook title.
3. Amazon Kindle is a great way to push your publication and to drive traffic to your book's listing. This one is a little more complicated but still, pretty easy to accomplish. Digital Marketer has done an excellent job of explaining how it's done here...so why should we gild the lily?
4. As an addendum to the first point, utilize free tubes like YouTube and Vimeo. Get yourself interviewed by a PR authority in your field, have the interview recorded, edit it accordingly and throw it up on either of those sites. This will give you a chance to visually and vividly share why your ebook should be purchased.
These tips have worked for us and we're pretty sure they will work for you. An ebook is an excellent opportunity to create a source of income for yourself or your company, so invest some time into planning and give it a shot!
