A new campaign.
I took the first six days of May as my benchmark sales run rate, and started a new campaign with a new set of ads. This campaign is a bit different:
There are three ads, each with it's own landing page.
Ad number one uses "Thriller" key words, and lands on a specially designed page on my website.
Ad number two uses "Suspense" keywords, and lands on Smashwords with a 40% off coupon.
Ad number three uses "Mystery" keywords, and lands on the Amazon Deliverables page. There is a "free" offer for the book for Amazon Prime members.
I also priced the ads at $0.30 max price. That will be much more economical than the last campaign.
I'll post an update later when the campaign has made more progress.
