I'm on a few author forums on fb.
Ads don't seem to be great, of all of them a well-produced instagram ad seems to yield the highest return. I've heard of a lot of people loosing money on ads.
There are like book lists where you can do a promo which seems to work sometimes. Just reading people on here, getting reviewed somewhere got Teb an uptick, and doing an AMA on reddit r/fantasy seemed to do wonders for Eli, but I haven't finished my book. I've tried light promoting of some anthologies that I'm in, but tbh I have NO idea what I'm talking about and have had very little success on this end so I probably shouldn't have posted
