What I'm dealing with is the invisibility factor right now. Despite having taken out ads on Facebook and Linked In, I just don't think anyone knows the book is out there. Facebook indicates I got 70 clicks for my money (it was a free ad) but no sales? This doesn't seem possible. When it first came out, in 1983, it sold several thousand copies. Anyway, giveaways for reviews is a good idea. How do I go about it?
Let me put this into perspective for you: how long have you been actively looking for readers?
Me? 4 years. I've been writing fiction for 4 years. I've been publishing for the last 2, nearly all being short fiction, a novella, some non-fiction, some freelance. My first novel was released with a publisher last week and there's been a scramble of folks trying to get an autographed copy of it for Christmas, even though shipping from Canada means that it's nearly doubling the cost of the book if they just ordered it off a website.
4 years ago, no one knew my name. Hell, my mother struggled to remember it. Now, mostly no one knows my name. That's an improvement.

This isn't a race. Take some time to get to know other authors and some readers. Do a handful of guest blogs. Go comment on blogs. Leave off the blog comment signature (it's just tacky anyway, I find) - the email and website gets listed whenever you comment on most blogs through your name. Go and get to know people. Write some more books. Sell some short fiction to magazines. Attend a local convention.
Take some time.
ETA: Corrected the signature thing to make it clearer
