Cold audiences: new to you in every way.
Warm audiences: aware of you, possibly interested in your product.
Hot audiences: they've already pre-ordered, but need love and attention. *see also, fandoms
You're not. You're me, in fact! Hey, buddy, I've been there.
LOL. I wish. (To my readers: I LOVE YOU. I love you just as much if you've only bought one of my books, and aren't sure about the others.)
That's normal, too.
* sends a newsletter
* books a promo blast
* discounts a title (or their publisher does it, maybe taking them by surprise)
What they don't say is, know who you're targeting. And how. And why.
FB ads are an art. I am not that artist. That's normal!
Know what your goal is, and work back from there.
Or pick something else that achieves the same goal.
The math doesn't work on a 99 cent book. There is almost no way to make a 99 cent product that you earn maybe 35 cents on (or less if you're with a publisher) profitable using a cost-per-click ad model.
The people who do it are making the money elsewhere.
So if you're starting something new: a new name, a new series--that's not the time to be betting the farm on a cold audience appeal.
I know, don't shout at me, but:
1. write more books.
I'm going to drink a cocktail in five minutes, I don't care if that's not what you wanted to hear. ;)
And start a new series. Start over, but don't drift far. Write YOUR THING, again.
I know. Fifty fans do not pay the bills. But don't abandon them, and their numbers will grow.
That's step 1. That's not all.
Like what?
a. Write a short story or a novella each, and bundle them together for a limited time anthology that would appeal to all of your readers.
b. Offer each others' first books to your core readers.
MAKE. THE. FIRST. ONE. FREE.
If you are making nothing on a series right now, if you have one and it's dead--make the first book free. What's the worst that could happen?
