I figure I'd put it here instead of a new thread, but I tried Written Words Reader Reach ads for Facebook, because I've never advertised on Facebook for a variety of reasons. I went into this with the expectation that I would not recoup my investment on the book advertised, and I was right. However, my goal was getting my name into the Facebook ecosystem as a scifi author where it never had been beyond the readers who already follow me. It's been a month, and I can't see any increase in sales that might be attributable to the Reader Reach ads. Now, granted, this method is in its infancy so I won't be too harsh, and the cost is a business expense which my publishing company can afford. I'm tempted to try their Amazon Reader Reach ads simply as an experiment with no expectations just because. As for BookBub, I've received nothing but rejections for the last 27 months and over a 100 submissions, after a dozen successful campaigns over the space of three years, so I'm pretty much done with them.
