I'm branching out my advertising process for my paranormal thriller novel Night Walk. Today I posted an ad on GoodKindles.net. It was really easy to do. The entire process was automated and my ad was live in a few hours. The prices are very affordable as well. You have to pay with Paypal, but hopefully you already have an account.
I also did a link share (which required a separate email), so I have an entry on the GoodKindles AUTHOR WEBSITE LIST
Now I get to wait and see how many sales come pouring in. Hopefully millions.
