If you want to increase sales you should get some reviews up there on Amazon. If you have a mailing list you can offer a limited number of free private ebooks to beta readers and encourage recipients to leave an honest review. That's standard practice on Amazon. The only stipulation is the review has to be voluntary and honest. Ideally you'd already have that in place on launch day but it's not too late.
