Not asking for keywords here. No trade secrets that you don’t want to share.
But as far as marketing goes, what do you do? What’s that look like? How much of your income does it end up being? Are you a one trick pony? What hasn’t worked for you? What do you wish you’d done differently? Where would you point a new writer/indie pubber to go find that information?
I’ll start. One trick pony here.
Paid newsletter services. Bookbub, Freebooksy, Robin Reads, Book Sends. Rarely: Read Cheaply and Book Gorilla.
No calendar regularity. I just take note that income dips and drop an ad, or four. I do keep an .xls with results and dates so I don't double up.
No AMS, FB, or BB per-click ads. Might one day. Maybe. When I feel the need to learn because I don’t want to pour money into a drain.
Ads average to roughly 7% of monthly gross.
Done differently: Wish I’d not promoted until I had four books out, one set to free.
You're up, Kip.
