Spike Your Initial Ranking

In advance of the release of your book compile a list of people you can "gift" a copy to.

Your net costs to gift a 99 cent book is about 65 cents since you get 35% commission. However, it only cost 89 cents to gift a $2.99 Kindle. At a 70% commission rate you'll get back $2.10 for every $2.99 book you gift.

Find 100 - 200 people and over the first 3 days of release sent them a "gift". This will likely get you in to the top 10 of niche where others will notice you. Not a bad investment for under $200.
